G FCC Emission Designators: How to Find Them An FCC emission designator is a seven-character string that represents the bandwidth, modula-

tion, and other characteristics of a transmitted radio signal. This information is required when ap-

plying for an FCC license. The designator assigned to your equipment depends on the particular sub-model of the product line you are licensing. In some cases, multiple designators are used to cover product variants such as base stations, remotes, indoor/outdoor units, frequency band, etc. An updated and official list of emission designators is maintained on the FCCs website at the following link: https://apps.fcc.gov/oetcf/eas/reports/GenericSearch.cfm Once the site has been reached, proceed as follows to determine your designator:

1. At the top of form in the box labeled Grantee Code: enter E5M. This is the code for GE MDS products. 2. At the bottom of the form in the box labeled Show x Records at a Time, enter a sufficiently large number (i.e., 300) to display all GE MDS records on file. Press Enter. 3. Once the list appears, it can be searched to locate the particular model you are seeking information on. To the left of each entry, there is a document icon. Click the icon to display the equipment authorization report. 4. Scroll down to the section labeled Equipment Specifications to locate the appropriate emission designator. If additional assistance is required, contact GE MDS using the information given at the end of this manual. 2.2 Front Panel All access to Master Station modules is made from the front of the unit after removing the pro-

tective cover. To remove the cover, simply grasp the sides and pull out with a slight rocking mo-

tion. Tether strips on the ends of the cover are available to keep it linked to the chassis when it has been removed from its installed position. The tethers allow the cover to rest just below the front panel during service work. Figure 2-3. MDS Master Station, Front Panel Connections & Indicators

(Representative arrangement; Module types vary based on product configuration) Master Station modules are factory installed and cabled. All modules are installed on slide-in as-

semblies and secured to the chassis with knurled fasteners. The illustration above shows the modules installed in a redundant configuration. For a non-redundant configuration, blank plates are used in place of the redundant power supply and radio modules, and a non-redundant version of the Alarm/Relay module will be installed. The table that follows lists the module types availa-

(Other configurations possible for external items such as duplexer or cavity filter) MDS Master Station MDS 05-6399A01, Rev. G 16 INSTALLATION PLANNING 3.0 This section covers pre-installation factors that should be considered when installing the Master Station. Careful planning will help achieve optimal performance from the radio. After reviewing this section, refer to the step-by-step installation procedures beginning on Page 23. The specific details at an installation site may vary, but there are three main requirements for in-

stalling the unit in all cases:

Adequate and stable primary power An efficient and properly installed antenna system Correct interface connections between the Master Station and any connected equipment. Figure 3-1 shows a common arrangement of the MPRS Master Station as used in a multiple ad-

dress radio network. The system shows both SD and legacy x710 remote transceivers in use. De-

pending on order options, the Master Station can communicate with remotes employing Ethernet signaling, serial signaling, or a mix of both. Figure 3-1 Application Example MDS 05-6399A01, Rev. G MDS Master Station 17 3.1 Applications The Master Station is designed for point-to-multipoint data transmission in utility SCADA com-

munications, transactional systems, and telecommunications systems. The wireless network pro-

vides communications between a central host computer and remote terminal units (RTUs) or other data collection devices. In such an arrangement, the operation of the radio system is trans-

parent to the computer equipment. Repeater and Polling Remote Operation (MPRS Only) In a system using FCC Part 90 repeater and polling remote, the polling remote radio operates in half-duplex mode and the repeater operates in half-duplex or full-duplex mode. The SD Master Station can be used as a polling remote, or as a repeater. Refer to Page 43 for details on configur-

ing the radio for repeater operation. Simplex and Switched Carrier Operation System-wide simplex operation is achieved by switching the Master Station carrier on to trans-

mit, and then off to receive. The same frequency is used for both transmit and receive. In MPRS Master Stations, switched carrier, half-duplex mode works in the same way, except dif-

ferent frequencies are used for transmit and receive. Refer to Page 57 for details on configuring the radio for simplex operation for SD radios. 3.2 Network Management MPRS Network-Wide Diagnostics When operating with SD radio interfaces (MPRS), the Master Station offers network-wide diag-

nostics capability, sometimes referred to as DLINK Diagnostics. Network-wide diagnostics com-

munications is a packetized diagnostic capability that provides the following advantages:

You can gather diagnostic data over a large radio network without disrupting the system communications flow. When required, you can increase diagnostics communications speed by actively collecting diagnostic data. You can access diagnostic data for each radio in the network from any radio diagnostics port in the network. You can broadcast certain messages to all radios in the system simultaneously. You can use the Master Station to poll remote radios in its radio system for diagnostic data. For more information on the implementation of network-wide diagnostics, refer to the GE MDS Net-

work-wide Diagnostics Handbook (P/N 05-3467A01). MPRS Network Management Using PulseNET PulseNET uses the SNMP, Netconf, and DLINK protocol to monitor the SD Master Station

(MPRS) and downstream devices. The Master Station can be connected locally using either COM1 or COM2 serial or through Ethernet using TCP. Refer to the section Dlink on Page 48 for more information about configuring DLINK on the Master Station. PulseNET remotely discovers and monitors Master Stations and other SD or x710 radios on the network using DLINK and other Orbit radios with SNMP and Netconf. The locally connected 18 MDS Master Station MDS 05-6399A01, Rev. G radio may be a Master, Repeater, Polling Remote, or Remote. This locally connected radio must be configured as the DLINK root radio to be discovered with DLINK. Downstream radios should be configured as node. PulseNET uses passive polling to discover the root radio and all of the node radios downstream. Passive polling allows monitoring without interrupting pay-

load data transmission. In order for PulseNET to discover SD Master Stations in the network, DLINK must be enabled and properly configured. Refer to the section Dlink on Page 48 for information on how to con-

figure DLINK. 3.3 Redundant versus Non-redundant Operation A redundant configuration means that the Master Station has two complete transceiver boards and power supplies installed in the enclosure. In the event of a failure in the primary equipment, the controlling logic switches to the stand-by unit. The stand-by transceiver board is constantly operating and its operational readiness is monitored. However, the power amplifier in the stand-

by board is not operating when it is in stand-by mode. In a non-redundant configuration, there is only one transceiver board installed in the enclosure, and back-up transceiver board operation is not possible. Transceiver boards may be moved from one Master Station to another; however an additional transceiver board cannot be added to a non-redundant Master Station. Redundant or non-redun-

dant operation is automatically detected by the platform manager, and the active transceiver is automatically selected. Installing or replacing a transceiver board causes the board to communi-

cate briefly with the Platform Manager to establish which transceiver board will operate as the active board and which operates as the stand-by. For more information, refer to section 8.4 Re-

placing Modules on Page 124. When redundant power supplies are present, both supplies are actively operating; meaning there is no concept of an active vs stand-by power supply. If the system detects a loss of power on one of the power supplies, an alarm will be generated until power is restored. 3.4 Antennas and Feedlines Antennas The Master Station may be used with a number of different antennas. The exact style and gain factor depend on the physical size and layout of your system. Antennas of this type are available from several manufacturers, including GE MDS. Contact your factory representative for details. Connection is made to the station via N coaxial connectors at the rear panel. Feedlines The selection of an antenna feedline is very important. Poor quality cable should be avoided, as it will result in power losses that may reduce the range and reliability of the radio system. The tables that follow show the approximate losses that will occur when using various lengths and types of coaxial cable in the 400 and 900 MHz bands, respectively. Regardless of the type used, the cable should be kept as short as possible to minimize signal loss. MDS 05-6399A01, Rev. G MDS Master Station 19 Table 3-1.

nected data equipment to a single-point ground, keeping all ground leads as short as possible. The Master Station should be grounded using the #6-32 screw and star washer provided for this purpose on the rear panel. The use of a lightning protector is also recommended where the antenna cable enters the equip-

ment building; bond the protector to the tower/mast ground, if applicable. All grounds and ca-

bling must comply with applicable codes and regulations. Figure 3-2. Rear Panel Grounding Screw MDS Master Station MDS 05-6399A01, Rev. G 20 3.6 Data Interface Connections Ethernet Data Interface (RJ-45) The Ethernet interface supports both radio management and payload data transport functions. For radio management, connecting via a web browser provides enhanced functionality and ease-

of-use over serial/USB methods. Web-based management is the preferred and primary means of accessing the transceiver through the built-in Device Manager. SSH may also be used on this connector, and provides the same CLI based user interface availa-

ble via the serial/USB interfaces. See section Ethernet Interfaces on Page 102 for electrical information and connector pinout. Serial Data Interfaces COM1 and COM2 provided on the front of the Platform Manager module serve as the serial inter-

face ports for payload data, radio management, or diagnostics. Management is also available through the mini USB port. The default factory configuration for these serial ports depend on the type of radio modules that are installed. Table 3-3. Default Serial Port Assignment COM2 Product variant COM1 Serial Payload Data System Console MPRS MPRL System Console System Console These ports are user-configurable for specific applications. The procedures for changing their de-

fault operation are provided later in this guide. Not all PCs have a serial port. If one is not available, a USB-to-Serial adapter and appropriate driver software may be used to provide serial connectivity. These adapters are available from several manufacturers, including GE MDS. MPRS Serial Data Connection When used as a data port for an SD Radio Module in Transparent or x710 modes, some pins on COM1 and COM2 have special behavior determined by configuration. DCD (Data Carrier De-

tect) is asserted when the radio received an on-frequency signal. RTS (Request-to-Send) can be configured to key the transmitter when asserted. CTS (Clear-to-Send) can be configured to go high after the programmed CTS delay time has elapsed (DCE), or can be configured to key an-

other connected radio when RF data arrives (CTS KEY) The included Com Port Adapter Cable 73-2434A25 can be used to convert the units RJ-45 serial jack to a DB-9F type connector. MDS 05-6399A01, Rev.

Mini USB The Mini USB port can be used to management the radio through a scriptable command line in-

terface (CLI) using the proper USB drivers available at www.gemds.com. Connect to the man-

agement PC using the included Mini USB Cable. Once the PC registers the device driver, the port will auto baud. The USB port provides CLI management only and cannot be used for net-

work diagnostics or for payload data. Alarm Output and 4-Wire Audio Alarm and audio signals are provided on the Alarm or Alarm/Relay module. Refer to Table 6-22 for details on pinout and signal descriptions. Audio signaling and alarm outputs are software configurable. Refer to Section 5.0 Device Management for more information. 22 MDS Master Station MDS 05-6399A01, Rev. G INSTALLATION PROCEDURES 4.0 This section presents the steps necessary for installing the radio and connecting it to associated equipment. After completing these steps, the radio is ready for in-service operation. 4.1 Unpacking and Inspection Check the contents against the packing list secured to the outside of the shipping box. Accesso-

ries and spare parts kits, if any, are wrapped separately. Inspect all items for signs of damage. Save all packing materials in case you need to ship the radio in the future. 4.2 Installation Steps The radio should be installed in a relatively clean, dust-free environment that allows easy access to the connectors and indicators. Air must pass freely over the rear heat sink and around the unit for proper cooling. Follow the steps below to install the unit and prepare it for initial startup. The rear heat-sink will get hot under continuous or high duty-cycle transmission. Use caution handling the unit while in operation. 1. Mount the Unit. The unit may be rack-mounted (2U high) in a 19-inch rack cabinet, or may be placed on any sturdy tabletop or other flat surface. The installation site should be free of excessive dust, and should have adequate ventilation. The chassis should be posi-

tioned so that all interface cabling will reach the required connectors. a. When rack mounting, the rack ears can be installed in one of three positions to al-

low flexibility in the mounted depth of the chassis. The unit should be mounted so as to maximize airflow around the rear heat sink. 2. Ground the Chassis. Use the ground screw provided at the rear panel to connect the ra-

dio to a safety ground (NEC Class 2 compliant), which bonds the Master Station, antenna system, and connected data equipment to a single-point ground. Keep all ground leads as short as possible. 3. Connect Antenna Feedlines. All coaxial antenna connections are made to the Type-N connectors on the rear of the unit. The number of connections depends on options or-

dered, including duplexer options, as follows: Separate TX and RX; Combined TX/RX;

wired for an external notch filter with RX Out, RX In and combined TX/RX. MDS 05-6399A01, Rev. G MDS Master Station 23 Figure 4-1. Internal Duplexer, Triple N connectors Figure 4-2. Internal Duplexer (or internal T/R switch), Single N connector Figure 4-3 External duplexer or dual antennas, Double C connectors

(TX and RX ports pass directly through) 4. Install the Data Interface Cabling. Interface connections are made to the front of the Platform Manager module. Typical connections for most sites include:

MDS Master Station MDS 05-6399A01, Rev. G 24

- Serial DataAttach data equipment to the front panel COM1 and/or COM2 ports. The unit is hardwired as a DCE device (DB9-F to RJ-45 connector, GE MDS part no. 73-2434A25).

- Ethernet LANAttach data equipment to the ETH1 and/or ETH2 port. The auto-sensing MDIX feature allows either a straight-through or crossover cable to be used. Where applicable in the steps that follow, secure all cable connections with the locking screws provided. 5. Connect Primary PowerThe Master Station is powered using one or two power sup-

ply modules that work in tandem. The modules may be AC, DC, or a combination of both. The following tables list each type and key operating parameters. Table 4-1. AC Power Supply Module Module Input Power Current Rating 6755 100-220 VAC, 50/60 Hz 120W Max. All DC power supply modules have chassis isolated inputs and a diode bridge for floating ground, positive ground, or negative ground installations. These modules include a keyed power connector with screw-terminals. Strip the wire leads to 6mm (1/4 inch) and insert them into the wire ports provided. Be sure to observe the polarity shown below. Tighten the binding screws securely and insert the connector into the module. For compliance with CSA, torque thumbscrews to 10in-lbs. Table 4-2.

tion 5.0 Device Management If serial-based cabling is used for configuration, an adapter may be required at the PC, as many PCs do not offer a serial port. In such cases, a USB-to-Serial adapter

(with appropriate driver software) may be used. These adapters are available from a number of manufacturers. 7. Radio, Alarm/Relay, and Duplexer ConnectionsThe Alarm/Relay module provides two alarm outputs, one for major and one for minor alarms. This module also provides TX/RX audio, PTT (TX keying), and analog RSSI connections. See Alarm/Audio Inter-

face on Page 117 for pinout connections. All other required connections on the front of the unit are cabled at the factory per or-

dered options. 8. Add connection of battery backup, as applicable. Initial Startup & Operation The radio is designed for continuous, unattended operation, but does require some minimal pro-

visioning before operation. This section explains the use of the radios indicators and provides steps for initial startup of the equipment. Once a unit is provisioned, operator intervention is not required, except to power the unit up or down, or to change an operating parameter. Operation of the radio can be started by simply connecting primary power to the unit. Module LED Indicators All LED indicators are on the front of the unit. Platform Manager, Radio, and Alarm Modules include LEDs. A redundant unit will be populated as shown above. A non-redundant unit will have only one Radio Module and a different Alarm Module without RF connections. 26 MDS Master Station MDS 05-6399A01, Rev.

m r a A l 6834 6846 Figure 4-5 LED Indicators 6846 6847 Normal Indications When power is first applied, the following events occur in a normally working unit:

All front panel indicators light briefly The ACTIVE LED for the selected transceiver board lights. On SD radio modules, The Power LED will begin to flash indicating they have not yet communicated with the platform manager. The Power LED and Alarm LED will light on the Platform Manager card. At this point the platform manager is performing a pre-boot validation of the firmware to ensure that all required security signatures are in place and valid. The Alarm LED will turn off and the Power LED will begin to flash. At this point the platform manager is booting and initializing the system. Once the platform manager initializes the transceiver module, the Power LED will stop flashing and turn solid. Maximizing RSSI Since the Master Station almost always uses an omni-directional antenna, maximizing signal strength is done at the remote sites where directional antennas are typically used. An RSSI stronger than -90 dBm is desirable. Refer to Section 5.0 Device Management for information on monitoring the RSSI for the Radio Module. MDS 05-6399A01, Rev. G MDS Master Station 27 5.0 DEVICE MANAGEMENT This section describes the steps for connecting a PC, logging in, and setting unit parameters. The focus here is on the local serial/USB console interface, but other methods of connection are available and offer similar capabilities. The key differences are with initial access and appear-

ance of data. The MDS Master Station offers several interfaces to allow device configuration and monitoring of status and performance. These include local serial console, USB, NETCONF, HTTP/HTTPS, and Secure Shell (SSH) for local and remote access via the WAN and LAN networks. The serial console, USB, and SSH services offer a command line interface (CLI). There are three user ac-

counts/roles for management access: admin, tech, and oper. User accounts can be centrally man-

aged with a RADIUS server, with RADIUS accounts being mapped to one of the three user ac-

counts/roles. Refer to MDS Orbit MCR Technical Manual (05-6632A01) for details on config-

uring RADIUS authentication. The MDS Master Station is designed for high security environments. As such, man-

agement of the device does not support Telnet, but instead implements the more secure SSH protocol. 5.1 Pre-Configured Settings The unit is highly configurable to meet field requirements, but comes pre-configured as follows:

COM1 is configured at a baud rate of 115200, 8N1 for transparent serial payload for MPRS master stations, and local console for MPRL master stations. COM2 is configured to operate at a baud rate of 115200, 8N1 and is enabled for local console operation. USB is enabled for local console operation (proper system drivers must be installed on the PC connected to the MDS Master Station to use the USB port as a virtual serial device;

these drivers are available from the GE MDS website). The Ethernet ports are bridged together, with spanning-tree protocol either enabled

(MPRS), or disabled (MPRL), with a default IP address of 192.168.1.1/24. 5.2 One-Time Recovery Passwords The MDS Orbit platform employs extensive security measures to prevent unauthorized access. As such, there are no hidden manufacturer passwords or other backdoors found in less secure products. If a password is lost, there is no way to access the unit, except by using a one-time password

(OTP) for recovery. The user must create this OTP manually. Without a one-time password, the unit will not be accessible, and the hardware will need to be replaced. The factory will not be able to assist you if a password is lost, so creating a one-time password is strongly encouraged. One-Time Passwords: How They Work One-time recovery passwords put control directly and exclusively in the users hands. They are similar to spare keys for a lock. If you make a spare key, and put it away safely, you can take it out to quickly gain entry when your primary key is lost. If you dont make a spare, you are al-

ways at risk of locking yourself out. 28 MDS Master Station MDS 05-6399A01, Rev. G A one-time recovery password is different from the one used to log into the unit on a routine ba-

sis. It is only for use when the primary password is lost or forgotten. When a one-time password is used to log in, that password is automatically revoked from the list of passwords created. (You may create up to five one-time passwords at one time, and more can be created if some get used). Once used, a password cannot be used again for log-in to the unit (hence the name one-time password) Creating a One-Time Password To create a one-time recovery password via the console, enter the following command, where

<selected function> is either factory-reset or login

> request system recovery one-time-passwords create function selected function A one-time password is automatically generated and displayed on the screen. Copy this password and save it in the desired location on your PC. There is no way to ever view it again from the command line console, so be sure it is properly saved. To create additional one-time passwords (up to a total of five), repeat the step above. Logging in With a One-Time Password Logging in with a one-time password can only be performed from the local serial or USB con-

sole. Note the local serial cannot be used if configured as a payload or diagnostic interfaces for SD radios (MPRS). You also cannot use a one-time password when connecting to the unit re-

motely. Therefore, in some configurations, the USB console is the only option. To use the one-time password for log-in, proceed as follows:

At the username prompt, enter the word recovery. At the password prompt, paste in the one-time-password saved earlier on your PC. Using a one-time-password forces the unit to perform the function which was previously defined when the password was created:

factory-resetThe unit resets its entire configuration to factory defaults loginThe unit allows logging in with admin privileges Special case: If someone has disabled console access on the USB port, the login prompt will still be present on that console, but only one-time-passwords will be accepted. This is done to provide a way to recover the unit in the case where the USB port has been disabled and the unit cannot be accessed via TCP (for example; SSH). Deleting a One-Time Password As noted earlier, a one-time password is automatically revoked when it is used for log-in. A re-

voked password may be replaced, but it must first be removed from the list so a new one can be generated. Any of the five stored passwords may be removed on demand. As long as there is a free slot, an additional password can be created, up to the maximum number of five. Logs are generated when the user creates, deletes, or logs in with a one-time-password. To remove an ex-

isting password from the list, proceed as follows:

Enter the command request system recovery one-time-passwords delete identifier <X>, where <X> is a number from the currently available one-time passwords. This identifier is not reused. If all five passwords have been created, then ID 1 can be deleted, and the next created password will be at ID 6. MDS 05-6399A01, Rev. G MDS Master Station 29 The current list of passwords may be viewed by issuing the command show system recovery one-

time-passwords. The following is an example output from that command. On the unit shown, only two passwords have been stored. Password 1 or 2 can be deleted from this list. IDENTIFIER FUNCTION STATUS DATE CREATED

Where type is one of the following values:

<type>-<slot>/0/<port>

Interface Type Abbreviations Type Description eth sd ln wifi Ethernet Interface SD Radio Module LN Radio Module WiFi Interface Slot-0 is the slot identifier for the platform manager, while slots 1-3 map to the available inter-

face slots in the chassis. Ports are zero-based and map to the port number of the given interface type in the specified slot. Note that not all interface types have port values that are non-zero (e.g. An SD radio module only has one port, so it will always be 0) The center 0 value in the interface name is always 0, and is reserved for future use. Examples of valid interface names are eth-0/0/0 The first Ethernet port on the platform manger card in slot-0 eth-0/0/1 The second Ethernet port on the platform manager card in slot-0 sd-2/0/0 The SD Radio module in slot-2. ln-1/0/0 The LN Radio module in slot-1 Logical (non-physical) interfaces such as bridges and VLANs use free-form names and can be renamed by the user. 5.5 Configuration via the Device Manager The Device Manager is a built-in software tool that works with your PCs browser to provide an intuitive, web-style presentation of all unit information, settings, and diagnostics. Device man-

ager is accessible through ETH1 or ETH2 using a web browser. Minimum browser requirements: IE10 or later, Chrome, Firefox, or Safari. For security, web access can be enabled/disabled via the CLI using the command % set 32 MDS Master Station MDS 05-6399A01, Rev. G services web http(s) enabled true/false General Configuration For initial configuration of the Master Station, perform the following steps:

1. Connect the unit to a PC via an Ethernet connection. 2. Configure your PC network settings to an IP address on the same subnet as the unit. The default subnet mask is 255.255.255.0. For IP addressing the Master Station uses a routing prefix expressed in CIDR notation instead of specifying a subnet mask. The CIDR notation is the first address of a network, followed by a slash character (/), and ending with the bit-length (max 32) of the prefix. A subnet mask is expressed in dot-decimal notation. For example, 192.168.1.0/24 is equiv-

alent to specifying 192.168.1.0 with a subnet mask of 255.255.255.0. 3. Open a web browser and navigate to the IP address of the unit (default Ethernet IP ad-

dress is 192.168.1.1). The initial sign-in prompt appears. 4. Enter the username and password (admin is the default entry for both fields), then click Sign In. 5. On first-time login, the Initial Setup Wizard will appear and provide guidance for general device setup. This is disabled after the initial setup has been complete but may be re-run at any time by accessing the Wizards link on the left side of the screen, and clicking Ini-

tial Setup. Key items that should be reviewed and/or set for the radio include:

Create one-time programmable passwords for unit recovery Change login passwords (to maintain security) Evaluate default factory configuration and lock the unit down to the required security level When the Initial Setup wizard completes, to configure SD interfaces (MPRS), select Wiz-

ardsSD Setup, which steps you through initial SD Radio Module configuration. Key items that should be reviewed and/or set include:

G MDS Master Station 33 Keying mode Repeater Configuration (if necessary) Serial data interface configuration Legacy DLINK settings Similarly Wizards Interface Setup will allow the user to configure the LN radio. 5.6 Interface Configuration Understanding A serial cable (RJ45 cable with proper ETH to DB9 converter) may be used to connect to a COM port on the unit to access the CLI. The default serial console settings are 115200 bps with 8N1 format. A mini-USB-to-USB cable may also be used to connect to a Computer in case no serial port exists. If a mini-USB connection is used, the computer must contain the appropriate device driver. A driver for serial operation can be found on GE MDS website. Configuring The screen below shows console access to the COM1 serial and USB port:

For serial packets over 255 bytes it is recommended that a cts-delay time of at least 90ms be used to account for the VTIME delay of the over-the-air sending unit. Hardware Flow Control Modes When port is not being used as a SD payload or SD diagnostics (DLINK) port:

DCE

- CTS follows RTS after a programmable CTS delay.

- If the units input buffer approaches a full condition it can deassert CTS regard-

less of state of RTS. CTSKEY

- Based on legacy MDS devices including TransNET, the device will act similar to a DTE but will provide signaling on the CTS line instead of the RTS line.

- When the first character of a transmission is ready to be sent to the serial port, the unit shall assert CTS and delay for CTS delay time expiration before outputting the first character.

- After the last character of a transmission is output from the serial port, the unit shall keep CTS asserted until the expiration of CTS hold time. CTSKEYPLUS 36 MDS Master Station MDS 05-6399A01, Rev. G

- The unit shall support flow control (Throttling) on the RTS pin. The device is ex-

pected to be wired via null modem to an external DCE device. The CTS line of the external DCE device drives the RTS line of the unit. Statistics for the Serial ports and IP Payload 1, 2, 3 are located under the active SD radio interface (Interfaces sd-x/0/0 Status Statistics). See section 5.9, SDMS Interfaces, for more details. 5.7 LAN Understanding This section will cover only the basic configuration of Ethernet ports and bridges. For full details on the configuration of more advanced features, please reference the MDS Orbit MCR Technical Manual (05-6632A01) The Master Station has external Local Area Network (LAN) ports (ETH1/2 ports) that can be used to connect to a local (wired) LAN. It supports both IPv4 and IPv6 addresses and may be as-

signed multiple IP addresses. The LAN port can be assigned static IP addresses or a dynamically allocated address can be assigned using DHCP. The LAN port should be assigned IP addresses only if it is a routed interface (that is, not in a bridge). Configuring To configure the LAN interface, select the eth-0/0/0 or eth-0/0/1. As shown in the screens below, there are five groups of configuration settings that can be configured: General ETHx specifics, IPV4, QOS, Filter, and NAT Basic Config Interfaces eth-0/0/x Basic Config Figure 5-1.

For information about VRRP setup, refer to VRRP Virtual RouterRedundancy Protocol in the MDS Orbit MCR Technical Manual (05-6632A01). 5.8 Bridging Understanding The unit supports transparent bridging of LAN, and in firmware versions of 3.0.0 and higher, WiFi and SD networks. The LN network supports Ethernet payload since its release in 4.0.0 The bridge forwards traffic between LAN interfaces and wireless interfaces at the layer-2 of OSI model. This allows LAN and wireless clients to be in the same IP sub-network. The bridge learns the clients locations by analyzing the source address of incoming frames from all attached networks. For example, if a bridge sees a frame arrive on LAN port from Host A, the bridge concludes that Host A can be reached through the segment connected to LAN port. 40 MDS Master Station MDS 05-6399A01, Rev. G Through this process, the bridge builds a forwarding table (the learning process). When a frame is received on one of the bridge's interfaces, the bridge looks up the frame's destination address in its forwarding table. If the table contains an association between the destination address and any of the bridge's ports aside from the one on which the frame was received, the frame is for-

warded out the indicated port. If no association is found, the frame is flooded to all ports except the inbound port. Broadcasts and multicast also are flooded in this way. The bridged network is addressable via the bridge interface (a virtual interface). The interfaces that are in the bridge are called bridged interfaces. The interfaces that are not in the bridge are called routed interfaces. Bridging is performed between bridged interfaces. Routing is performed between routed interfaces. The bridge interface itself is a routed interface. In firmware versions less than 3.0.0, the SD interface is not a bridgeable interface as there is no packet or packet-with-MAC mode support in these versions of firmware. Configuring For full details on configuring bridge interfaces, please see the MDS Orbit MCR Technical Manual (05-6632A01). 5.9 SDMS Interface Understanding The configuring of SD interfaces on the Master Station is performed through a virtual interface called sdms (SD Master Station). This virtual interface, much like a bridge interface, is com-

prised of one or more sd-nic member physical interfaces. Each installed SDM Radio Module contains a single sd-nic. All configurations applied to the virtual SDMS interface will be propa-

gated to all member sd-nic interfaces. This insures that all SD radio interfaces in the system are using identical configurations so that interface fail-over is seamless. To access the full suite of SD configuration options, select the sdms interface from the interfaces drawer on the left-hand menu. Understanding the use of Virtual Radio Channels (VRCs) VRCs allow over-the-air data to be directed to specific interface ports (IP or Serial) on the radio. Conceptually, this can be pictured as creating pipes for delivery of data to the desired radio in-

terfaces. VRC works by associating data from a specific port (IP and Serial) with a VRC channel number

(1, 2, or 3). Each port at the receiving end then filters incoming data based on the associated VRC number. The Virtual Radio Channel (VRC) feature is only supported in Packet w/MAC modes. It is not supported in Transparent or x710 mode. To create the pipes that direct data to the desired ports, a route must be established using the IP Payload Configuration Menu (or payload serial settings on the general configuration menu for serial data). The default setting is to listen to all channels.) The Talk on parameter is used to specify the VRC used for sending the data stream over the air, while the Listen to parameter specifies the VRC(s) for incoming data. Any combination of the three VRC numbers may be entered in the selection fields. Figure 5-2. Virtual Radio Channel (VRC) Concept illustrates the relationship between the VRC settings and the routing of data between units. MDS 05-6399A01, Rev. G MDS Master Station 41 Figure 5-2. Virtual Radio Channel (VRC) Concept Understanding the use of Media Access Control (MAC) An important feature of the transceiver is Media Access Control (MAC). The radios MAC is specifically designed for use with narrow bandwidth, half duplex radio networks such as those commonly used in licensed telemetry systems. When the MAC is enabled, it provides efficient support of multiple data traffic models including multiple hosts, synchronous and asynchronous polls, and report-by-exception (push traffic). MAC ensures that every transceiver in the network has an equal probability of gaining access to the radio channel when it has data to send. Coordination of Channel Access The main objective of the MAC is to coordinate channel access for all radios in the network, pre-

venting data collisions that can occur with simultaneous transmissions from radios on the same RF channel. With MAC operation, a single radio is configured as an Access Point (AP) and other units are designated as Remotes. The AP serves as the controller of the RF network. Remotes re-

quest permission from the AP to use the RF channel before sending payload data, thus avoiding collisions of data, and creating a highly reliable wireless network. The MAC is responsible for allocating which unit gets access to the broadcast medium (the RF channel), when, and for how long. Data Validation Additionally, the MAC validates all messages and purges corrupted data from the system. Suc-

cessful delivery of data is ensured through the use of retries and acknowledgements. Minimal overhead is used to accomplish these tasks, which translates to increased bandwidth efficiency of the radio channel with minimal latency, ensuring that messages are delivered in a timely manner. 42 MDS Master Station MDS 05-6399A01, Rev. G Status Tab The Status tab on the sdms interface page gives an overview of the current state of the sdms in-

terface. The information displayed is described below:

General This section shows a general overview of the SDMS interface. The current status of the relay switch, as well as which SD NIC is currently active is displayed here. The NIC Status table is composed of the following columns:

Chassis Slot The slot in which the SD NIC was discovered. Board Temperature The current temperature in degrees C as measured on the surface of the SD NIC. The colored indicator will transition to yellow and red as the NIC approaches its operational limits. PA Temperature The current temperature in degrees C of the power amplifier on the SD NIC. The colored indicator will transition to yellow and red as the NIC approaches its operational limits. Configuration From the sdms interface page, all SD related configuration options can be specified. Primary SD network configuration can be found under the Basic Config tab, more advanced options can be found under the Advanced Config tab, and operational actions can be found under the Ac-

tions tab. Basic Config Tab General Settings The Basic Settings contains important RF and modem selections for radio operation. MDS 05-6399A01, Rev. G MDS Master Station 43 Members The Master Station (sdms) interface is a logical interface that is composed of one or more physical SD interface cards (sd-nic). The members configuration item is the mapping between the logical sdms interface, and the physical sd-nic cards. A single sd-nic resides in each SDM Radio Module. This is factory configured to contain SDM Radio Modules in slot 1 and slot 2 of the Mas-

ter Station. If the Master Station is a non-redundant system with only 1 Radio Module, this will contain only sd-1/0/0. Radio Mode The radio can operate in one of several modes. The available selections

- Packet with MAC With and without AES Encryption MDS Master Station MDS 05-6399A01, Rev. G are:

44

- x710 When using the Master Station in a legacy x710 network.

- Transparent With and without AES Encryption. (Transparent w/AES Encryp-

tion requires an all SD radio network.) Modem Type This setting determines the over-the-air data speed and bandwidth of the radios transmitted signal. All radios in the network must use the same modem setting to communicate with each other. The default setting is Modem 9600, but it may be set to any of the selections shown in Table 5-2. Modem Selection vs. Speed, Bandwidth &

Sensitivity. The table also lists modem sensitivity ratings for the various modems. Note that some modem choices are limited based on the model purchased. RF Output Power (dBm) The RF output power may be set between 30 and 40 dBm (1 to 10 watts) in 1 dBm increments. The default setting is 40dBm. This setting represents the output power at the Radio Module. Output power at the antenna port on the back of the unit will be roughly 2dB to3dB less depending on configuration. This is due to cable, switching, and duplexer losses. Full power is not required in many cases, and lower settings will place less demand on the power supply and reduce the chance of interference with other stations. Only the power necessary to carry out reliable communications should be used. Transmit/Receive Frequency The receive and transmit frequencies may be viewed or set here. Frequencies must be entered for the radio to operate. Consult your station license to determine the authorized frequencies for your system, and enter them exactly as listed. Keying Mode Keying mode must be set to one of the following values:

- Data Radio will key upon receipt of payload data.

- RTS Radio will key upon receipt of an RTS (request to send) signal on the se-

rial port. RTS keying mode is only supported when the radio is in x710 mode.

- Data or RTS Radio will key upon receipt of either payload data or an RTS (re-

quest to send) signal on the serial port.

- Continuous Radio will be continuously keyed. This is primarily used in a trans-

parent streaming repeater configuration. Continuous keying mode is only supported in x710 mode, or in transparent mode when operating as a repeater. System ID Provides the possibility for Frequency Re-use. System ID offers nine unique choices including the default value of NONE. The setting NONE is required for mixed networks comprised of MDS legacy and SD products. SD-only networks can utilize the Frequency Re-use feature by setting the System ID to a common value [1-8] for all radios in a specific network. System ID offers approximately 20 dB of additional co-channel isolation when operating networks on the same frequency. Note that proper system design is required. Operational Example: SD System Alpha has eight units and SD System Beta has eight units. A user wishes to occupy frequency 952.1235 MHz on both of these systems. Proper system installation has been adhered to in both networks. System Alphas units would all be set to System ID = 1, System Beta's units would be set to System ID = 5. Both systems will now operate on the same desired frequency. Examples of valid and invalid arrangements are shown in Figure 5-3 and Figure 5-4, re-

spectively. MDS 05-6399A01, Rev. G MDS Master Station 45 Figure 5-3. System ID Example Valid Arrangement Figure 5-4. System ID Example Invalid Arrangement FCC Part 90 Repeater Mode Repeater mode must be set to one of the following values:

- None This is the default value, and is used when the Master Station being con-

figured is not to be used as a repeater in the network.

- Repeater This value should be selected when the Master Station being config-

ured is to be installed as a repeater in the network, and will not have devices con-

nected to it that will be polled, such as attached RTUs.

- Repeater With Local Data This is the same as Repeater but should be used when data-collection devices such as serial RTUs will be attached directly to the repeating Master Station. MDS Master Station MDS 05-6399A01, Rev. G 46 Allowed Ethernet Packet Types When operating in packet-with-mac mode, and sending Ethernet traffic, this option will restrict the types of Ethernet frames that will be sent over the air. Options are:

- None This will prevent any Ethernet frames from being transmitted over the air.

- All All Ethernet frames will be sent over the air, regardless of type.

- Unicast Only Only unicast packets will be sent over the air.

- Unicast and ARP This is the default value and will only allow unicast frames, or broadcast ARPs to be transmitted over the air. Serial Payload Port The front-panel serial port that will be used for serial payload communications. This can be set to COM1, COM2, or disabled if the system will not be used for transmitting serial data. The default value for this is COM1. Serial port settings such as baud rate and byte format are located under Services Serial Ports. Payload Buffer The transceivers buffer provides a way of handling data 'over-runs', where more data is passing through the COM port than can be immediately handled by the unit. When the payload-buffer is on, any such data is stored up and processed in the appropriate order. Payload Serial Talk VRC / Payload Serial Talk 2 VRC Serial data received on the primary/secondary serial payload port will be tagged with this VRC and sent over-the-air. Payload Serial Listen VRC / Payload Serial Listen 2 VRC Over-the-air payload traffic that is tagged with this VRC that the Master Station receives will be transmitted out of the primary payload serial port. Encryption When the Master Station is being used in a network of only SD radios, over-the-air (OTA) encryption may be enabled. The Master Station uses AES-128, passphrase-based encryption to secure both payload, and Dlink traffic. If the radio is operating in transparent mode, there is a separate passphrase for payload and Dlink traffic. If the radio is operating in packet or packet-with-MAC mode, there is a singular passphrase for all traffic. Payload Encryption Phrase The encryption phrase to be used for over-the-air payload data. This string must be at least 8 characters, and no greater than 38 characters. Table 5-2. Modem Selection vs. Speed, Bandwidth & Sensitivity Modem Type Se-

Dlink Dlink is a GE MDS-proprietary protocol used for diagnostics communications. Unit This parameter identifies the radio in the wireless network with a specific ID during diagnostic sessions. For compatibility with legacy devices, the value must be 10000 or greater (2710 in hexadecimal). Type This setting identifies the radio as a Node, Root, Repeater, Peer, or Gate. Each of these are operating modes of the transceiver with respect to diagnostic/management activities. Mode Configure if Dlink will operate on a serial port, or via a TCP socket. Serial Mode Settings:

48 MDS Master Station MDS 05-6399A01, Rev. G

- Serial Port This setting determines which serial port to use COM1 or COM2. This must be different than the serial payload port. TCP Mode Settings:

- Security Mode When set to a value other than none, connections will be en-

crypted using a pre-shared key via TLS. The version specified by this parameter will be only version allowed by the server.

- TCP Port The TCP port that the Dlink service will listen on.

- IPv4 Addr Optionally configure the service to only attach to the specified IPv4 Address. This is useful when traffic is being separated into data and management VLANs. If no value is specified, the service will accept connections on all config-

ured IP addresses.

- IPv6 Addr Optionally configure the service to only attach to the specified IPv6 Address. This is useful when traffic is being separated into data and management VLANs. If no value is specified, the service will accept connections on all config-

ured IP addresses. Enabled Enable or disable diagnostics functionality. Setting it to ON configures the radio to pass the diagnostic link protocol (DLINK) over the radios COM2 management port. MAC Settings When operating in packet with MAC mode, MAC specific settings can be configured here. Device Type The role this device will be performing in the network. If this device is operating as a repeater, the MAC device type MUST be 'remote'. MDS 05-6399A01, Rev. G MDS Master Station 49 MAC Retries If a message is not acknowledged after transmission it will be resent. This value controls how many times the radio attempts to resend the message before discarding it. Time to Live When a message arrives from the payload interface(s) it is time-stamped and queued for radio transmission. If the radio cannot transmit the message before the Time-to-Live (TTL) value (in seconds), the message is discarded. This helps prevent stale or old data from being sent over the air. SAF Network (Access Point only) If this device is in use in a Store-And-Forward network, enable this option. Repeater Network (Access Point only) If this device is in use in a repeater network, enable this option. Payload 1/2 Inter Packet Gap The inter-packet gap is a timing setting in ms used to delimit a packet on the serial interface. Too short of a time can cause serial streams to be combined into one large packet instead of two smaller ones. Too long of a time can slow down the communications channel. Transparent Rx Timeout This setting is similar to the timing parameters for Payload 1/2 Inter-Packet Gap, but it applies to data received over-the-air. It tells the radio how to build an Ethernet packet based on a transparent data stream received over the radio channel. Peer to Peer Access Point Options:

- Peer to Peer Enabled If enabled, the AP will allow enabled peers to send traf-

fic through the AP to other enabled peers by rebroadcasting their transmissions to all other remotes in the system.

- Ethernet Rebroadcast Type When rebroadcasting peer-to-peer Ethernet traf-

fic, only the selected type of traffic will be rebroadcast to other remotes on the network. Remote Options:

- Rebroadcast Serial If enabled, serial traffic originating from this device will be rebroadcast by the AP to other remotes in the network. The AP must have peer-

to-peer rebroadcasting enabled.

- Rebroadcast Ethernet If enabled, Ethernet traffic originating from this device will be rebroadcast by the AP to other remotes in the network. The AP must have peer-to-peer rebroadcasting enabled. Remote Detection Service When enabled, the unit uses DLINK messages to detect connected remote radios. Detected re-

motes are displayed in a table. Enabled Enables the remote detection service. Default FALSE. Mode Options are Passive or Silent (Default Passive).

- Passive This mode broadcasts passive DLINK messages when there is other data to be sent. This causes no interruption to data on the network, but the remote radio will MDS Master Station MDS 05-6399A01, Rev. G 50 not send a response until it also has data to send. This is the preferred mode when no other network monitoring systems are being used.

- Silent In Silent mode, the unit transparently sniffs DLINK messages that are already on the network rather than send out its own. This is useful in a network where DLINK diagnostics are already in use by other devices or network monitoring systems. Polling Interval (Passive mode only) This value specifies how often a broadcast message should be sent to detect radios. Range: 0 4294967295, default 5. IP Payload Under the IP Payload menu, up to three instances of the IP Payload service may be configured. The IP Payload service can operate in 4 different modes:

- TCP Server

- TCP Client

- TCP Server/Client

- UDP Common Options:

- Enabled Set to true to enable this IP Payload configuration.

- IP Payload Mode The mode in which this instance of the IP Payload service should operate. The details of these modes are shown below.

- Talk on VRC (Only in packet-with-mac mode) The Virtual Radio Channel that data from this IP Payload instance will be tagged with when transmitted over the air.

- Listen to VRC (Only in packet-with-mac mode) Over-the-air data tagged with this Virtual Radio Channel will be handled by this IP Payload instance.

- Modbus TCP RTU Conversion (Does not apply to UDP mode) When enabled, the IP Payload server will convert packets between MODBUS TCP and MODBUS RTU formats.

- Inactivity Timeout When set to a value larger than 0, the connection will be closed after the specified number of seconds without any data activity. Each of the IP Payload modes have different use cases and configuration options, as described below:

TCP Server:

The TCP server mode allows IP connections to be established with the Master Station. Data re-

ceived on this TCP socket will be transmitted over the air to remote SD radios as if the data was received on the payload serial port of the Master Station. Over-the-air serial data originating from a remote SD radio will be transmitted out of this TCP socket. This mode of operation can be thought of as a remote terminal server, not to be confused with the SD remote radios Ter-

minal Server functionality. MDS 05-6399A01, Rev. G MDS Master Station 51 TCP Server specific configuration options include:

- Multihost Enabled Multihost is a legacy feature that has been superseded by the Packet w/MAC feature. It should only be used in legacy systems or in special use cases. Enables or disables multihost. Default = FALSE

- Multihost Timeout This is the time, in milliseconds, that a multihost server waits for a response from a poll before moving on to the next queued polling message. Range: 0 512 ms, Default = 500 ms

- Multihost Unexpected Data Behavior Specifies what the server should do when unexpected data is received from a remote device. Options: Drop, send all, send 1, send 2, send 3. Default = Drop

- Transparent Rx Timeout The time, in milliseconds, to wait after last received transparent data byte before an ethernet packet is created and sent upstream. Range: 0-512, Default = 10 ms

- Local IP Port The TCP port number that the server will listen for connections on.

- IPv4 Bind IP If the Master Station is configured with multiple IP interfaces; you can specify that the IP Payload service only will listen for connections on one of the IP addresses of the system. This is useful in VLAN configurations where you wish to only make the IP Payload server available on a specific VLAN in the system. 52 MDS Master Station MDS 05-6399A01, Rev. G TCP Client:

The TCP client mode allows the Master Station to connect to a TCP server when there is traffic to send. This mode of operation is not often used in Master Station configurations, but may be useful in certain applications. TCP Client specific configuration options include:

- Server IP Address The IP address of the server the Master Station is to connect to.

- Remote IP Port The TCP port that the server is listening on. TCP Server/Client:

As the name implies, TCP Server/Client is a combination of the TCP Server mode, and TCP Cli-

ent mode. In this mode, the Master Station will listen for incoming TCP connections and pass data exactly as in TCP Server mode. However if there is no active server connection, and over-

the-air payload traffic arrives at the Master Station, the Master Station will establish an outgoing TCP connection to a remote server and transmit that data to the remote server. A use-case for this mode of operation is if you wish to have the protocol reliability of TCP, but do not wish to main-

tain active TCP sessions across your network. MDS 05-6399A01, Rev. G MDS Master Station 53 TCP Server/Client specific configuration options include:

- Local IP Port The TCP port number that the server will listen for connections on.

- Server IP Address The IP address of the server the Master Station is to connect to.

- Remote IP Port The TCP port that the server is listening on.

- IPv4 Bind IP If the Master Station is configured with multiple IP interfaces; you can specify that the IP Payload service only will listen for connections on one of the IP addresses of the system. This is useful in VLAN configurations where you wish to only make the IP Payload server available on a specific VLAN in the system. UDP:

When operating in UDP mode, the IP Payload service uses the connectionless UDP protocol. Since UDP is connectionless, there must be receiving sockets at each end of the connection to allow for bi-directional communications. In this mode, when an application has traffic to send out over the SD network, it will establish a UDP connection to the Master Station and transmit the payload data. When the Master Station receives over-the-air payload data from remote SD radios, the Master Station will establish a UDP connection to the application and transmit the payload data. These connections are not persistent, and as such must be established for each transmission. Unlike TCP, transmissions are not guaranteed when using the UDP protocol; how-

ever UDP has a far smaller network overhead than TCP, and as such will result in lower latency. 54 MDS Master Station MDS 05-6399A01, Rev. G UDP specific configuration options include:

- Local IP Port The UDP port number that the server will listen for connections on.

- Server IP Address The IP address of the server the Master Station is to connect to.

- Remote IP Port The UDP port that the server is listening on.

- IPv4 Bind IP If the Master Station is configured with multiple IP interfaces; you can specify that the IP Payload service only will listen for connections on one of the IP addresses of the system. This is useful in VLAN configurations where you wish to only make the IP Payload server available on a specific VLAN in the system. IPv4 This configuration section allows you to configure either a static or dynamic (DHCP) IPv4 ad-

dress to the SDMS interface when it is not a member of a bridge or VLAN interface. For full in-

formation on applying IP addresses to interfaces, see the MDS Orbit MCR Technical Manual

(05-6632A01). MDS 05-6399A01, Rev. G MDS Master Station 55 Firewall Filter The firewall filtering rules to apply to this interface when it is not a member of a bridge or VLAN interface. For full information on applying firewall filters to interfaces, see the MDS Or-

bit MCR Technical Manual (05-6632A01). VLAN The VLAN configuration section is used to configure the SDMS interface to be a member of a VLAN. For full information on configuring VLANs and adding interfaces to existing VLANs, see the MDS Orbit MCR Technical Manual (05-6632A01). 56 MDS Master Station MDS 05-6399A01, Rev. G The NAT configuration section is used to configure network address translation (NAT) on the SDMS interface. For full information on configuring NAT on interfaces, see the MDS Orbit MCR Technical Manual (05-6632A01). NAT Advanced Configuration Tab Advanced Configuration

- Soft-Carrier Dekey Specifies how long (in ms) to wait after the removal of the keying signal before actually dropping the transmitters carrier. The default setting is 0, but it may 57 MDS Master Station MDS 05-6399A01, Rev. G be set to any value up to 255 ms. In most cases, no change is required from the default setting. A possible exception is when the transceiver is inter-working with certain early-

generation MDS radio equipment.

- Push to Talk Signal Specifies the sensing polarity of the PTT line. This must be configured to one of the following values:

- Off PTT line is not used.

- Hi The PTT line is active-high.

- Lo The PTT line is active-low.

- Push To Talk Delay Specifies a brief time delay after a keying event, which must expire before the radio is allowed to transmit. The allowable range is 0 to 255 ms, with the default being 0.

- Clear To Send Delay Specifies a brief time delay between when an RTS (ready-to-

send) signal is received and when the CTS (clear-to-send) signal is returned. The allowable range is 0 to 255 ms, and the default is 0.

- Switched Carrier B Modems In some networks, the Master unit is not keyed continuously (Ckeyed), and transmits only when it has data to send to Remotes. This is known as Switched Carrier operation. The Switched Carrier setting is only for use with the 9600B modem (for compatibility with MDS x710 radios). In such networks, the Remote radios should have the Switched Carrier setting turned ON. The default setting is OFF which assumes B-modem operation with a continuously keyed Master. Ckey operation only applies to Master units operating full-duplex and does not apply to legacy-packet or packet with MAC modes. When operating continuously keyed, latency is decreased and AFC operation on legacy remotes may be improved. Switched carrier operation, when low latency is not required, is recommended when operating in high ambient conditions to reduce power consumption and heating.

- Force DCD to Asserted Some systems require a constant Data Carrier Detect (DCD) signal. This setting allows the radio to be configured to provide a DCD signal without the need for special cabling. Enabling Force DCD to Asserted will cause the RX LED on the radio interface to turn on, regardless of whether the radio is receiving data or not.

- Data Key Hold Time-out When operating in data key mode, this parameter specifies the number of character-times the transmitter will remain keyed for after the last character it receives. For networks with the demand for a higher modem speed than the baud rate of the serial port, this parameter can be adjusted from 1 to 10 characters. This parameter gives the overall network better performance by preventing frequent key-up and key-down sequences between characters. This only applies to networks with all SD radios.

- Simplex Mode This controls whether or not the Master Station will be running in simplex (switched carrier) or full duplex mode. When simplex is enabled, TX and RX are switched onto a single RF interface. A Master Station without an internal duplexer with a single antenna output must have simplex mode enabled.

- Dlink Mode (B Modems) Legacy products that only support B-Modems do not have support for Dlink. Newer products such as the MDS SD have the ability to support Dlink 58 MDS Master Station MDS 05-6399A01, Rev. G even when using B-Modems. Depending on site-specific requirements, this value may need to be changed to bypassed in order to work with legacy products. It is recommended to leave this value set to auto unless there is an explicit need to change it.

- Rx Mute The number of milliseconds to mute the receiver after transmitting data. Receive muting might be required when you configure the radio as a full-duplex polling remote communicating through a repeater. It prevents the radio from hearing its own transmissions ('echoes') from the repeater, which might cause software application errors.

- Rx Timeout Enable When enabled, the radio will alarm if nothing has been received over-the-air in 'Rx Timeout Delay' minutes. This can used to detect if the receiver has failed, or if there has been a failure with the antenna.

- Rx Timeout Delay When Rx Timeout is enabled, this is the number of minutes to wait for a received signal before raising an alarm.

- Transmitter Timeout Enable (modem none only) When this timer expires, the radio dekeys and alarms. This can be used to detect a stuck keysource condition.

- Legacy Packet Compatibility When the radio-mode is configured for packet-with-mac, enabling this option will cause the radio to operate in a legacy packet mode. This is not full packet mode as found on SD radios, as there is no support for listen-before-talk.

- Modem Receive Tolerance Changes the receive tolerance of the modem. This value should always be set to normal unless instructed to change it by GE MDS technical support for specific applications.

- Data Device Mode (x710 mode only) This value controls the device behavior of the radio when operating in x710 mode. In DCE mode, CTS will go high following RTS, subject to the CTS programmable delay time. CTS KEY mode, the unit is assumed to be controlling another radio. The radio will still key based on the RTS line, but the CTS line is used as a key-line control for an external radio. CTS is asserted following the receipt of RF data, but not until after the CTS programmable time has expired. (This gives the other radio time to key.)

- CTS Hold Time (x710 mode only) Used in CTS KEY mode, this command sets the amount of time in milliseconds that CTS remains present after transmission of the last character out the RXD pin of the DATA port. This 'hold time' can be used to prevent squelch tail data corruption when communicating with other radios.

- RSSI out Enabled When enabled, the current RSSI value will be available as a DC voltage level on the RSSI out pin of the alarm/relay module. NOTE: This feature requires SD NICs that are capable of generating an output voltage based on RSSI. If you attempt to enable this feature on hardware that does not support it, you will receive an error message preventing you from committing the changes.

- RSSI out 0-Point When RSSI out is enabled, this is the RSSI level (in dBm) that will result in an output voltage of 0 mV

- RSSI out mV per dBm When RSSI out is enabled, this is the voltage (in mV) that will be produced for each dBm of signal strength above the level specified in rssi-out-0-point. e.g. Given a zero point of -120dBm, and a mv-per-dbm value of 50mV, an RSSI of -

84dBm would result in an output of 1800mV. MDS 05-6399A01, Rev. G MDS Master Station 59

- Bypass Rxmute This setting should be enabled only if instructed to by GE MDS technical support for specific applications. Audio Audio settings are only available for configuration when the radio is configured to oper-

ate in x710 compatibility mode.

- Audio Enabled If enabled, the radios transmit functionality will switch to analog whenever PTT is asserted.

- Rx Level Receive audio output level to modem (dBm). Received signal at the peak deviation will be scaled to the specified value. Valid range is (-20 0).

- Tx Level Auto Automatically adjust transmit audio input level from Modem.

- Tx Level Transmit audio input level from modem (dBm). A transmit input signal of the specified value will translate into the specified peak deviation for transmit. Valid range is

(-20 0).

- Emphasis When enabled, pre-emphasis is applied on the transmitter and de-emphasis is applied on the receiver. This setting is typically used in operation with voice radios.

- Squelch When set to auto, the transceiver will use its internal squelch to enable transmission of audio signals. When set to bypassed, the transceiver will transmit all audio signals regardless of level.

- Vox Enabled Enables or disables the integrated VOX threshold circuit.

- Vox Threshold The audio interface on the Master Station incorporates an integrated VOX circuit to sample the voltage produced by a connected audio device. When the voltage exceeds a user-defined threshold, Push to Talk (PTT) is activated, resulting in the transmitter being enabled. The VOX circuit detects a voltage in the range of 0-2 Volts. A single number in the range of 0-15 is used to describe the desired threshold level. For example a value of 7 is approximately 1 volt. MDS Master Station MDS 05-6399A01, Rev. G 60 Enabled Alarms This configuration section controls which of the various alarms that can be generated on the SD NIC will be propagated up to the platform manager for system logging. All alarms default to be-

ing enabled, and should remain enabled unless there is an explicit need to disable one. RTU Simulator The units built-in RTU simulator generates random data similar to what would be supplied by an external RTU connected to the radio. It is useful for system testing within the radio network by providing realistic data to pass over the radio channel.

- RTU Enabled Enable the built-in RTU simulator.

- RTU Number The RTU number the simulator will respond to requests for. Remote SD Reprogramming This section contains various parameters for the broadcasting of new firmware to remote SD ra-

dios. Please see section Remote SD Reprogramming on page 65. Actions Force Alarm From the Force Alarm menu, you can force the SD radio interface cards to enter a test alarm state. To activate an alarm, select which radio slot to alarm, and click the Perform action button. An Alarm Test entry will be created in the Event Log and the external alarm output status is changed. This can be useful when testing event logging and propagation across a network, or when testing equipment connected to the alarm output contacts on the Master Station. When ena-

bled, the alarm will assert for 30 seconds, and then deactivate. If active, it can be manually deac-

tivated prior to timeout by deselecting the slot number of the radio and clicking the Perform ac-

tion button again. MDS 05-6399A01, Rev. G MDS Master Station 61 Link Test The primary use of the Link Test is to verify that a specific radio's settings are consistent with the initiator including: Assigned frequency, unit number setting, encryption (if enabled), etc. Also collected at the same time is an indication of link quality. All radios are always ready to re-

spond to a Link Test message. Only the initiating radio requires configuration when using the Link Test screen and it is only available when operating in Packet w/MAC mode. A summary of data statistics is displayed on the right side of the screen, including transmit/re-

ceive packet counts, total bits, and total number of bit errors.

- Destination Address The unit address of the other radio being tested.

- Count The number of times for the message to be sent across the radio link.

- Timeout The time (in milliseconds) that will result in a timeout if no response is received within that period. 62 MDS Master Station MDS 05-6399A01, Rev. G Remote Management Command The Master Station has the ability to broadcast management commands to remote SD radios in the network. These commands are sent to all connected remote radios, and hence should only be used for making network-wide changes. The following action can be specified:

- Reboot All remote radios will reboot to the currently active firmware image.

- Set Radio Mode Change the radio mode of remote radios (x710/transparent/packet-

with-MAC)

- Set Frequencies Set the receive and transmit frequencies of remote radios.

- Set Modem Type Change the configured modem of remote radios.

- Set Transmit Tolerance Change the configured transmit tolerance of remote radios.

- Set System ID Change the configured system ID of the remote radios.

- Enable Bridge Enable or disable Ethernet bridging on remote radios.

- Enable Encryption Enable or disable OTA encryption on remote radios.

- Set Payload Encryption Phrase Change the payload encryption phrase on remote radios.

- Set Dlink Encryption Phrase Change the Dlink encryption phrase on remote radios.

(Only used in transparent mode)

- Set SCD Change the Soft Carrier Dekey value on the remote radios.

- Repeater Network Change Change remote parameters that may need to be configured when running in a network which uses a MDS Master Station as a repeater.

- Generic Dlink Message Broadcast a custom Dlink command to all units on the system. Arguments include the Dlink register to write to (in hex, no leading 0x), and the DLink value to write (in hex, no leading 0x). The hex argument values must be full octects (e.g. 0F instead of F. With the exception of the reboot command, these actions will cause permanent loss in connectivity to the Master Station until the corresponding configuration changes are made to the Master Station itself. Please see section Remote SD Reprogramming below. Remote SD Firmware MDS 05-6399A01, Rev. G MDS Master Station 63 RF Key Test Using the RF Key Test action, the active radio can be manually keyed (transmitter enabled) or de-keyed (transmitter disabled). This may be useful when diagnosing signal-strength on a remote receiver.

Spectrum Analyzer A unique feature of the transceiver is the ability to view the RF spectrum above and below the operating frequency using its built-in Spectrum Graph. Often, this can assist in diagnosing the cause of interference, or to view other signals near your operating frequency. To use the Spec-

trum Graph, you must first specify a center frequency and a scan width. The center frequency is the frequency that you wish the spectrum display to be centered on. The span frequency defines the width of the overall spectrum to be examined. Once the correct values have been entered, switch it on by sliding the on/off switch. The graph will automatically refresh itself every 5 seconds. To stop scanning, turn the on/off switch off. 64 MDS Master Station MDS 05-6399A01, Rev. G Remote SD Reprogramming OTA Reprogramming Overview This feature is for reprogramming SD remote radios only. This will not reprogram other Master Stations on the network. The DLink Root is the central location from which polling originates. Other locations in the network should be designated as Nodes which are the receiving stations. Over-the-air firmware upgrades should always be initiated from the Root. This ensures that all radios in the network will be properly updated. The Master Station broadcasts a series of messages to one or more remote nodes to accomplish the reprogramming process. The broadcast method is used to program the greatest number of radios in the shortest amount of time; however, the Master Station remains unaware of the num-

ber or success of downstream radios participating in reprogramming. During reprogramming, the status of the reprogramming will be available on all the radios partic-

ipating in the process. Because the initiator is broadcast-only this status can only indicate pro-

gress toward sending out of all of the messages. On the nodes, the progress toward completion of reception of reprogramming information is indicated. Receiving stations can automatically reboot to the new image after successful reprogramming. Alternatively, there is an OTA reboot command that can be broadcast from the Master Station to all receiving stations. This last option instructs the receivers to reboot to a specific firmware revi-

sion if available, and not already running at that revision. Reprogramming Parameters:

The setting for over-the-air reprogramming are found under the Advanced Config tab on the web UI.

- Channel Usage Set to either Intrusive or Passive as desired.

- Passive (Non-intrusive) operation piggy-backs reprogramming data onto nor-

mal payload data streams, thus allowing payload data to continue uninterrupted, but will be slower than intrusive operation. This mode requires payload data to be sent so that the reprogramming data can be carried. See Table 5-3 for reprogram-

ming times.

- Intrusive operation means that the payload application data will be interrupted while programming data is sent over the air. This is the fastest method of pro-

MDS 05-6399A01, Rev. G MDS Master Station 65 gramming radios over the air, but it comes at the cost of interruptions in the pri-

mary use of the radio network. For best results, data polling should be stopped during Intrusive Reprogramming. See Table 5-4 for reprogramming times.

- Block Size Sets the overall block size (in bytes) of each data packet. Default setting is 512.

- Auto-Reboot When enabled, the remote radios will automatically reboot after a firmware image upgrade. If disabled, the newly loaded image will not become valid until the remote radio is rebooted manually.

- Packet Size Specifies the size of the reprogramming data packets. Default size is 40.

- Retry Count Specifies the number of times each transmission is repeated. Default setting is 3. Decreasing this value will decrease reprogramming times, but increase the chance of a remote radio not properly receiving a packet.

- Download Delay Introduce a time delay before reprogramming begins. Typically, it is set to Short, but may be increased incrementally by selecting one of the extended delay times from the drop-down box (Short, Medium, Long, None) Table 5-3. Approximate Reprogramming Times - Passive Mode Modem Speed (bps) Approximate Time Required 4800 9600 19200 6 hours 1 hour, 30 minutes 1 hour, 30 minutes Radio assumptions: Signal strength -85 dBm or stronger, Packet Size: 40, Block Size:

512, Retry: 3, Download Delay: Short. Polling assumptions: Serial polling with 1-second poll time, sending random data at 50-

100 bytes. Slower polling times will significantly increase completion time. Table 5-4. Approximate Reprogramming Times - Intrusive Mode Modem Speed (bps) Approximate Time Required 4800 9600 19200 1 hour, 30 minutes 30-45 minutes 20-25 minutes Radio assumptions: Signal strength -85 dBm or stronger, Packet Size: 40, Block Size:

512, Retry: 3, Download Delay: Short Polling assumptions: Polling should be temporarily suspended while OTA reprogram-

ming is active. Start Reprogramming When ready to reprogram the SD firmware, click the Start Reprogramming action. 66 MDS Master Station MDS 05-6399A01, Rev. G

ming operation, navigate to the sdms interface status page. Cancel Reprogramming During the reprogramming operation the user has the ability to cancel reprogramming at any time either on the Master Station, which will affect all radios, or on individual receiving stations. Note that cancelling reprogramming at the Master Station results in all radios in the network hav-

ing only one (instead of two) applications programmed in their image banks. That is, the inac-

The term LN is used to denote all licensed narrowband modules within the Orbit family. Specific identification, such as LN400, is used when necessary to reference band-specific hardware. The LN NIC modules are reliable point-to-multipoint, wireless data transmission products. An LN NIC can operate as an Access Point or Remote. Licensed Narrowband modules provide robust long-distance communication in channel band-

width sizes of 6.25KHz, 12.5KHz, and 25KHz. The 700MHz Licensed Narrowband module sup-

ports channel bandwidth sizes of 50kHz as well. Depending on bandwidth, raw data rates range from 20kbps to 120kbps. The radio is suitable to interface both Ethernet and Serial controllers such as PLCs, RTUs and SCADA systems while offering greater throughput then traditional FSK solutions. The module utilizes QAM modulation, a highly efficient PA, and a direct conver-

sion receiver to provide dependable wireless communications. An advanced Media Access Con-

trol (MAC) provides advanced interference avoidance, error detection, retransmission, auto re-

peat, and guaranteed collision free data. 10-Watts of peak power and dynamic FEC extend cover-

age to up to 50 miles. The specifications for the LN100 NIC module:

ARP Cache Feature that limits over-the-air ARP traffic

Data and Header Compression facilities to use LZO data compression for payload and robust header compression to reduce packet overhead

FEC facility to selectively enable Forward Error Correction trading off speed and robustness

Allow Retransmit facility to enable peer-to-peer traffic In general, it is recommended that users start with the simplest configuration and then make pa-

rameter changes as necessary to meet specific needs. NOTE To meet country specific regulatory requirements, some parameter restrictions may be config-

ured by the factory. These settings can NOT be changed or modified by the user. See Table 6-14. LN Interface LED Descriptions for details on how to interpret the LEDs on an LN radio. Understanding the use of Virtual Radio Channels (VRCs) VRCs allow over-the-air data to be directed to specific interface ports (IP or Serial) on the radio. Conceptually, this can be pictured as creating pipes for delivery of data to the desired radio in-

terfaces. VRC works by associating data from a specific port (IP and Serial) with a VRC channel number

(1, 2, or 3). Each port at the receiving end then filters incoming data based on the associated VRC number. The Virtual Radio Channel (VRC) feature is is not supported in Transparent-Serial mode. To create the pipes that direct data to the desired ports, a route must be established using the payload serial settings on the general configuration menu for serial data. The default setting is to listen to all channels. The Talk on parameter is used to specify the VRC used for sending the data stream over the air, while the Listen to parameter specifies the VRC(s) for incoming data. Any combination of the three VRC numbers may be entered in the selection fields. Figure 5-2. Virtual Radio Channel (VRC) Concept illustrates the relationship between the VRC settings and the routing of data between units. 76 MDS Master Station MDS 05-6399A01, Rev. G Figure 5-5. Virtual Radio Channel (VRC) Concept Important Notes and Information Regarding EVM EVM (error vector magnitude) is dependent on the modulation format and should be used as a relative measurement of the link quality. A low EVM value indicates a better link quality than a high value. Algorithmically, using QAM modulation, the transceiver calculates the value by measuring the sample points of each "bit" and comparing it with the expected constellation based on the modem type.

- EVM is a metric of the quality of the received signal. It is a dynamic value that is computed only when data is received on the RF interface, and should be refreshed accordingly.

- Unlike RSSI which simply measures signal strength, EVM is a measurement of the "correct-

ness" of this signal. (This means how easily the received signal can be correctly demodulated.)

- In general the lower the EVM the better the quality. A strong link will typically show an EVM below 5. Adaptive Modulation The adaptive modulation mode (modulation automatic) allows directed traffic to adjust which modem is used on a per-transmission basis. Adaptive modulation works in both upstream and downstream mode. The mode selection varies between QPSK, 16QAM, and 64QAM. A signal metric score is used to decide which modem selection to use. The score is determined based on signal strength and packets received. Advanced configuration can be used to provide some con-

trol over the adaptive modulation thresholds. The primary use case for this feature is if an AP has some remotes that are close to the AP and could support a higher data rate and some farther away (or obstructed) that can only support a lower data rate. This mode allows the close remotes to take advantage of the higher data rate for MDS 05-6399A01, Rev. G MDS Master Station 77 the directed messages, when otherwise the whole network would have had to be run at the lower data rate. Note that broadcast or multicast data must always be transmitted at the lowest rate. We recommend keeping adaptive modulation set for most installations. Security Setting the security mode to EAP or PSK will enable device authentication. When enabled, the remotes will authenticate with the AP (PSK) or a backend RADIUS server (EAP) before they are allowed to pass data on the network. The authentication protocol is compliant with IEEE 802.1X. If device authentication is enabled, over the air data encryption can also be enabled. This ensures all over the air traffic is protected. When encryption is enabled, the device must occasionally ro-

tate the encryption keys. This rotation is logged in the event log with event type nx_auth. These events can be suppressed in the event log configuration to prevent them from filling the event log. See the MCR Technical Manual for instruction on controlling the event log. Basic configuration with defaults Navigate to: Interfaces / lnms ---> Basic Config / LN Radio Configuring Figure 5-6.

Members The ln-nic interfaces that are used for this configuration

Device Mode - Sets the role the radio will assume in the network.

- Remote (DEFAULT)

- AP

Network Name - The name of the network. Used to control what networks the radio connects to. Valid values: 1 to 31 letters (DEFAULT is mds_ln). The network name string is used to identify the logical network that the device should join. If the network name does not match, the device will log an event to identify network name collisions.

Data Compression Over the air compression

lzo - Compresses the over the air traffic with the LZO algorithm (DEFAULT) none - No data compression

Header Compression Enabled by DEFAULT. Enable/disable over the air robust header compression. This feature compresses IP headers to improve system performance, and is most useful in applications that rely on IP packets with small payloads, such as terminal server oper-

ations or MODBUS polling. This setting must match on each radio (Remote and AP).

Power - The transmit power of the radio: Valid values: 20 - 40 dBm DEFAULT is 40dBm

TX Frequency The frequency at which the radio transmits.

RX Frequency The frequency at which the radio receives.

Channel - Controls the channel bandwidth and symbol rate of the radio.

Modulation Sets the radios modulation. You may select automatic (adaptive modulation), or choose from three fixed modulations.

- Adaptive modulation (DEFAULT)

- QPSK 16QAM

-

64QAM

-

Automatic modulation adaptively selects which modem (QPSK, 16QAM, or 64QAM) is used on a per-transmission basis. This is useful in networks with some remotes close to the Access Point, and others farther away or obstructed. This mode allows the close remotes to take advantage of the higher data rate for the directed messages, while the remotes use a more conservative modulation. Radios with fixed modulation settings will operate only at the modulation that you specify. If the specified modulation is higher than the connection can support, no traf-

fic will flow. If the connection can support a higher modulation than the selected mod-

ulation, the radio will not take advantage of this and will continue to use the fixed modulation. We recommend that Adaptive Modulation be used in all cases other than bench tests. Theoretical throughput is based on modulation and channel settings. Please refer to Table 5-5 above. MDS 05-6399A01, Rev. G MDS Master Station 79

FEC -- Forward Error Correction is useful in controlling errors in weak connections. FEC encodes data in a redundant fashion to allow data correction in a noisy or weak connection without the additional overhead of retransmission.

- Disabled (DEFAULT). No Forward Error Correction will be used. This option provides the highest throughput and standard sensitivity, and is suitable for strong connections.

- Low Gain Provides better sensitivity, while still offering good throughput.

- Adaptive Provides the best sensitivity and standard throughput. Adaptive on a per-packet basis. NOTE It is critical to have FEC set identically on the AP and all Remotes. Figure 5-7.

G 5.13 Redundancy You may manage the behavior of a redundant Master Station. Navigate to System->Redun-

dancy. The Status tab shows the current relay switch status. Figure 5-19 Redundancy Status menu

Relay Switch Position (Forced A/Forced B/Automatic) Shows the current state of the relay cards manual override switch. Figure 5-20 Standby Equipped and Scheduled Failover The Basic Config tab contains the Standby Equipped and Scheduled Failover menus.

Standby Equipped This feature is designed to alert users when a redundant master station is experiencing a failure that may affect its ability to failover. When this feature is enabled, the system will alarm if the Master Station is a redundant configuration, and either a single NIC or a single power supply is detected.

Scheduled Failover Enabling this feature results in the unit performing automatic failover at a user-defined interval. For example, scheduling a failover period of 720 minutes results in the Master Station failing over automatically every 12 hours. MDS 05-6399A01, Rev. G MDS Master Station 97 o Enabled (Enabled/Disabled, default Disabled) o Period (1 43200 minutes, default 1440 (24 hours)) This is the interval at which the unit should perform failover. Perform Failover The Actions tab allows you to perform an immediate failover. If the Master Station is equipped with redundant radios, the active radio can be manually toggled by selecting the Perform action button. The manual toggle-switch on the alarm/relay board must be in the Automatic position for this operation to succeed. The toggle-switch will override all software-based control of which radio is active. 98 MDS Master Station MDS 05-6399A01, Rev.

AUDIO (MPRS Only):

- 4-wire audio circuits are connected to pins 1 through 4 as shown in Figure 6-10.

- Terminals 1 and 2 are for transmit audio input with a nominal 600 impedance.

- Terminals 3 and 4 provide receive audio output with a nominal 600 impedance. MDS 05-6399A01, Rev. G MDS Master Station 117

- Pin 5 connects to an external keying source. Shorting pins 5 to pin 7 can key the radio when PTT LOW is configured in software. When PTT is configured high in software, pulling PTT to 3.3V keys the radio. The interface is compatible with an external VOX adapter, although this product features an inte-

grated VOX circuit with digital threshold control. For applications using the external VOX adapter, 12VDC on pin 6 can be used to power the external module. ALARMS:

- Terminals 8 and 9 provide solid state relay contacts that close when a minor alarm is detected.

- Terminals 10 and 11 provide relay contacts that close when a major alarm is detected. You can redefine these relay contacts using the radios software (switched from minor to major alarm outputs, or vice versa). The contacts are rated for non-inductive loads up to a maximum 60 Volts (AC or DC) at 1 A. Analog RSSI (MPRS Only):

When enabled in software, an RSSI voltage of 0 to 3V corresponding to -120 to -70dBm is pre-

sent on this line.

(As viewed from outside the radio) Alarm/Relay Toggle Switch (6847 Only) For redundant units, the Alarm/Relay module includes a manual override toggle switch, which can be set into one of three positions to associate it with a particular radio. The toggle switch is locking, and must be pulled out to change positions. Switch functions are as follows:

- Up Radio A

- Down Radio B

- Center Automatic. When the switch is set to Automatic, the active radio is determined by radio module presence and alarm status. If only one radio module is installed (A or B) it is recommended that the switch be set to A or B, as appropriate. The non-redundant version of the Alarm Module does not include the Toggle Switch. Alarm/Relay RF Connections (6847 Only) For redundant systems, the Alarm/Relay module includes a RF Connections for both the A and B Radio Module, and RF OUT. These are all Dual FAKRA-SMB connectors. RF OUT is switched between Radio A and Radio B depending on the currently active radio. RF OUT is normally ca-

bled to the Duplexer tray faceplate, even on systems that do not include a duplexer. Redundant systems come from the factory already properly cabled between the Radio Modules, Alarm/Re-

lay Module and Duplexer tray faceplate. Connectors are keyed to ensure proper orientation. Non-redundant systems using the 6848 Alarm Module do not include RF Connections. 118 MDS Master Station MDS 05-6399A01, Rev. G 6.7 Duplexer Tray Current Master Station offerings always include a Duplexer tray whether or not an internal du-

plexer is included. The duplexer tray is cabled to the Alarm Relay Module, in a redundant unit, or to the Radio Module if non-redundant. This is cabled on the front of the master station from TX to RF-1 and from RX to RF-2. The cabling inside of the duplexer tray is dependent on the frequency plan, whether transmit or receive is on the higher frequency. If the master station was ordered with an internal duplexer and the user is changing from transmit high to transmit low, or vise versa, the cabling inside the duplexer tray may need to be modified. For master stations ordered before January 2017, the cabling to the duplexer depends on the fre-

quency plan. In this case, the duplexer tray will be labeled HIGH and LOW. For those units, ca-

ble as directed in Table 6-23 below. Table 6-23.

G MDS Master Station 119 7.0 SPECIAL CONFIGURATIONS 7.1 Migrating A Modem Networks Mitigation strategy for mixed SDx/x710 repeater networks using the A modem One key aspect of the MPRS MDS Master Station is that its backward compatible with the 9790. In many respects, in fact, the Master Stations performance is superior to that of the 9790. For example, the sensitivity of the Master Station is better than that of the 9790. However, one performance aspect in which the Master Station lags the 9790 is latency in both the receiver and the transmitter. In many applications, this latency hit of the Master Station is barely noticeable. A point to mul-

tipoint network is one of these applications. In other applications, such as streaming repeater ap-

plications, however, this latency hit needs to be addressed via user configuration in order to get the radio network up and running. Note that in most repeater network cases, the latency effect of the Master Station after this addi-

tional configuration will still be comparable to that of point to multipoint networks. Having said that, there are a few cases where additional delay will be required. In regards to the aforementioned user configuration, its worth noting that streaming repeater ap-

plications that employ Packet-with-MAC mode dont need to worry about this configuration. Also, users migrating from x710/transparent to Packet-with-MAC mode dont need to worry about resetting this configuration, since all the parameters involved are ignored in Packet-

with-MAC mode. User Configuration 1: Non-CKEY Repeater Network Case The following parameters need to be configured in the order in which they are described below. 1. SCD := A soft carrier dekey delay of greater than 0 needs to be configured on the polling remote and on the remotes to prevent the remotes from hearing their own transmissions. 2. PTT := If serial flow control isnt available at the remote sites (excluding polling remote site) and the O.T.A rate is faster than the effective baud rate, a push to talk delay may be required such that the Master Station repeater latency remains constant across back-to-

back 9710 transmissions. Note that the effective baud rate of 8E1 is smaller than that of 8N1. 3. BUFF := A custom BUFF delay may need to be configured if there are still large gaps in the data received O.T.A by the polling remote and the remotes. Multiples of 10ms should be used as a rule of thumb. Note that for modem 9600, baud 9600, a custom BUFF delay should not be required. The following table provides the appropriate SCD values for all the A modems that may be em-

ployed on a mixed SDx/x710 repeater network. Note that PR stands for polling remote. Note also that these values will work whether the remotes are keyed on RTS, DATA or both. These values do assume that flow control is either available or not available throughout the radio network. Note that the values are not symmetrical because of the transmit waveform differences between the SDx and the 9710 despite having the same configuration. 120 MDS 05-6399A01, Rev. G MDS Master Station A Modem 9600 SDx/SDMS Polling Remote SCD 8ms 9710/SDx Remote SCD 12ms The following table provides the appropriate PTT values for the various baud formats that are used with the most commonly used A modem in mixed repeater networks, that is, modem 9600.

The only differences are:

- The SCD values required at the remotes should be smaller

- PTT should never be required SDx/SDMS Polling Remote SCD 6ms A Modem 9600 Note: Completely error free performance is not achievable at strong signal because the 9710 takes errors due to a known 9710 receiver issue. 9710/SDx Remote SCD 8ms MDS 05-6399A01, Rev. G MDS Master Station 121 8.0 TROUBLESHOOTING If trouble occurs with the unit, verify that it meets the basic requirements listed below. These items should be checked prior to starting any detailed troubleshooting or calling for assistance. All units must have:

- Adequate and stable primary power

- Secure cable and wiring connections

- Proper configuration for the application

- ALL modules securely tightened into the chassis using at least 10 inch-pounds of torque. Most radio system problems are due to the failure of components outside of the transceiver such as a poor or broken feed line or antenna connection. This section will help you determine whether the problem is outside or inside the radio and, if in the radio, how to restore operation as quickly as possible. GE MDS does not recommend component-level repairs in the field. However, you can replace the radios major assemblies without using tools or test equipment. Section 8.4 Replacing Mod-

ules covers this in detail. Before starting any detailed troubleshooting, check the basic requirements at both ends of the link: primary power, secure cable connections, and proper antenna heading. In many cases, one of these causes poor operation or a complete loss of link service. 8.1 Interpreting Module LEDs The LEDs on the front of installed modules provide useful information when troubleshooting. Refer to Section 6.0 Master Station Modules for detailed descriptions for module LEDs. Power and alarm indicators are provided on Platform Manager (Page 102), Radio (Page 107), and Alarm/Relay modules (Page 108). Radio Modules also have TX/RX LEDs to show wireless ac-

tivity. Normal Operation During normal, operation, there should not be any Red LEDs illuminated. All illuminated LEDs should be BLUE or GREEN. 122 MDS Master Station MDS 05-6399A01, Rev. G Table 8-1. Status LEDs Normal Operation Platform Manager Active SD Radio Module Standby SD Radio Mod-

For telephone assistance, call (585) 241-5510, or visit our website at www.gemds.com for additional contact options. 8.4 Replacing Modules Component-level repair of a transceiver board in the field is not recommended due to the com-

plex nature of the circuitry and the use of surface-mount technology throughout the radio. You should return malfunctioning assemblies to the factory (or authorized service center) for repair or replacement. One approach to field-level servicing is to have spare modules available. Slide in modules are easily field replaceable, including Power Supply, Radio, Platform Manger, and Alarm/Relay Modules. Internal Duplexers can also be replaced in the field. In this way, you can quickly re-

move and replace a defective assembly with a working assembly. The following instructions de-

scribe the removal and installation of these assemblies. When installing Power Supply or Radio Modules, torque thumbscrews to 10 in-lbs, or approximately turn past hand tight, to insure optimum heat transfer through thermal contact connector on the rear of the unit. Power Supply Modules The two left-most card-slots on the MDS Master Station are dedicated to Power Supply Mod-

ules. To remove either of these assemblies, first disconnect the power supply cable. Loosen the two thumbscrews on the front of the module, then slide the module straight out. A Power Supply Module can be installed in either of the left-most slots on the Master Station. It will not engage if an attempt is made to install into any other slot in the chassis. To install, align the Module with the card guides and slide into the chassis until it engages with the backplane connectors. Push firmly on the faceplate of the module to ensure a good connection and hand-

tighten the thumb screws. The thumb screws should be further tightened to 10 in-lbs, or approxi-

mately turn past hand tight, to ensure optimum heat transfer through thermal contact connector on the rear of the unit. Connect the power cable first making certain that the supply is within the rating for the power supply module you have installed. Module ID Module Table 8-3.

Make sure the supply is within the rating for the module installed. On a redundant unit equipped with two power supplies, a supply can be removed, and a new sup-

ply can be installed, while the unit is powered and operational. Do not remove power supplies whose power source is still connected and active. Peripheral Modules including Platform Manager, Radio, Alarm, and Alarm Relay Modules. Peripheral slots on the Master Station include all slots between the power supply modules (on the left) and the duplexer tray (on the right). On an MDS Master Station, the peripheral slots are populated with the following modules, from left to right: Platform Manager, Radio Module, a second Radio Module if redundant, and an Alarm Module or Alarm/Relay Module if redundant. To remove peripheral modules, first disconnect cables attached to the faceplate of the module you are removing. Label connections if necessary to remember how connections are made. Loosen the two thumbscrews on the front of the module, then slide the module straight out, mov-

ing other cables out of the way as necessary. The Radio Module heat spreader gets very hot under normal operating con-

ditions. Always use caution handling recently powered Radio Modules. When removing a Radio Module, do not touch the heat spreader. It is recommended to pull the Radio Module out only part way, disengaging the module from the backplane and rear heatsink, and then allow the Radio Module to cool for several minutes before removing it fully from the chassis. To install a peripheral module, align the module with the card guides and slide into the chassis until it engages with the backplane. Push firmly on the faceplate of the module to ensure a good connection and hand-tighten the thumb screws. The thumb screws can be further tightened with a screwdriver. Radio Modules should be tightened to 10 in-lbs, or approximately turn past hand tight, to ensure optimum heat transfer through thermal contact connector on the rear of the unit. Reconnect faceplate cabling connections to other modules as necessary. Hot Swap Redundant Modules On a redundant unit equipped with two Power Supplies and two Radio Modules, these modules can be removed and/or installed while the unit is powered and operational. Replacing a Power Supply does require first removing the supply input for the module, but the alternate Power Sup-

ply can remain powered. The unit will continue to operate using a single power supply. When removing a Radio Module on a redundant unit, we recommend changing the selector switch on the Alarm/Relay Module to lock the active radio to A or B as appropriate before re-

moving the other Radio Module. This should be done even if the desired radio is already active. MDS 05-6399A01, Rev. G MDS Master Station 125 The manual override toggle switch is locking, and must be pulled out to change positions. Switch functions are as follows:

- Up Radio A;

- Down Radio B;

- Center Automatic. Once a new Radio Module is installed, the Select Switch should be returned to the Center (Auto-

matic) position for redundant operation. A newly installed Radio Modules may require firmware reprogramming and configuration update from the Platform Manager. Green alarm and power LEDs on the Radio Module will alternate quickly during this process. Allow up to 5 minutes for the synchronization process to complete. Internal Duplexer Tray The duplexer tray can be removed by first removing two screws on the top of the chassis holding the tray in place. Save these screws. Disconnect all cabling to both the faceplate of the duplexer and on the back of the unit. Once cabling and screws have been removed, push on the connectors on the back of the unit to free the tray from the chassis and then slide out the front. To install a new tray, slide the tray in allowing the connectors to push through the back of the chassis. Use the same screws to secure the front of the tray to the chassis and then reconnect cabling being careful to connect TX and RX cables from the Alarm Module to the correct faceplate connec-

tions on the Duplexer Tray. 400 MHz Notch-Type Duplexers You can generally change the radios transmit frequency up to 100 kHz without re-tuning the du-

plexer. The duplexers shown in Figure 8-1. 400 MHz Notch Duplexer can be aligned in the field by experienced technicians using high-quality test equipment. For assistance, contact GE MDS Technical Support for additional details about tuning. Figure 8-1. 400 MHz Notch Duplexer

(Adjustment generally not required for transmit changes up to 100 kHz) Duplexer alignment is a sophisticated procedure and a duplexer can be easily damaged if not handled carefully. It is highly recommended that you return duplexers needing realignment to GE MDS, or the original duplexer manu-

facturer, for alignment. In some cases, it may be more economical to replace the unit MDS Master Station MDS 05-6399A01, Rev. G 126 than to have it realigned. Bandpass-Type Duplexers These duplexers (Figure 8-2. 900 MHz Bandpass Duplexer) typically allow the transmitter fre-

quency to change up to 500 kHz without undesired results. Since this type of duplexer cannot be re-aligned in the field, we recommend contacting the GE MDS Technical Support Department if you suspect a duplexer problem or need one for a different frequency. Figure 8-2. 900 MHz Bandpass Duplexer

(Adjustment generally not required for transmit changes up to 500 kHz) 8.5 Testing and Removing an Internal Duplexer Testing If you suspect that the internal duplexer is not functioning properly, perform the following steps to determine if requires replacement:

1. Measure the RF power out of the antenna jack.

- If the power registers approximately +37 dBm (5 watts), the internal duplexer is probably functioning correctly (see Table 9-1. dBmVoltsWatts Conversion Chart for dBm-volts-watts conversion chart).

- If the power registers significantly less than +37 dBm, proceed with Step 2. 2. Locate the TX SMA connection on the front of the duplexer tray. 3. Using an adapter, connect the RF power meter to the SMA Cable on the front of the unit

- If the power registers +39 dBm, the radio board is functioning correctly.

- If the power registers less than +39 dBm, proceed with Step 4. 4. Use the front panel to switch to the alternate transmitter and again measure the RF power output.

- If the alternate transmitter registers +39 dBm, the internal duplexer probably needs replacing. 5. Before replacing the duplexer, verify that the highest or lowest frequencies marked on the duplexer are the same as radios transmit and receive frequencies or within the nominal operating range: 100 kHz for 400 MHz radios, and 500 kHz for 900 MHz radios. Removing the Internal Duplexer To remove the internal duplexer, follow these steps:

MDS 05-6399A01, Rev. G MDS Master Station 127 Disconnect the antenna cables from the back of the chassis. Internal Duplexer Cabling - A number of different duplexers can be installed in the ra-

dio. While the physical appearance of the duplexer may vary slightly, its operation and removal remain the same. Disconnect the SMA cables from the front of the duplexer tray Remove the two screws on the top of the unit that secure the duplexer tray into the front of the chassis. Carefully slide the duplexer tray out the front of the chassis by applying pressure to the antenna N-connectors on the rear of the unit. 128 MDS Master Station MDS 05-6399A01, Rev. G Remove four screws to remove the duplexer assembly from the tray MDS 05-6399A01, Rev. G MDS Master Station 129 Figure 8-3. Internal Duplexer Removal Use care when removing the duplexer. Physical damage may cause detuning. MDS Master Station MDS 05-6399A01, Rev. G 130 9.0 TECHNICAL REFERENCE DATA 9.1 RF Propagation Planning Establishing a reliable point-to-point radio link requires system planning and design. You should have an understanding of the physical parameters affecting propagation. The following material discusses these factors and will assist you in designing a dependable transmission path for your radio link. This section is intended for use as a guideline when planning transmission paths. It does not consider all of the local conditions that may be present, nor does it guarantee that ad-

equate signal strength will be obtained in a given system. There is no substitute for an on-the-air test to verify the predicted path results, and to check the overall operation of the radio system. To ensure a highly reliable path, a line of sight between both ends of the link is desirable. For short paths (up to 5 kilometers/3.1 miles), some obstructions might be acceptable, but the perfor-

mance of a blocked path is always less predictable than a clear path. Fresnel Zone Clearance As the distance spanned by a link gets longer, it is necessary to have more than just a grazing path between the two ends; the path must clear the ground or other obstacles by some percentage of a Fresnel zone. The Fresnel zone corresponds to the width or girth of the radio signal. There are first, second, and third Fresnel zones, but the first zone is the only one that has substantial effects on signal strength. The first Fresnel zone can be visualized as an oval-shaped volume between two station antennas

(Figure 9-1 ). As the width of the radio wave front gets blocked by obstructions, less of the signal can get to the receiver antenna. In addition to blocking the signal, obstructions in the first Fresnel zone may also cause multipath interference due to reflective and refractive signal paths. The reflected or refracted signal might arrive at the receiver out of phase with the desired signal and cause a canceling effect. Figure 9-1 Fresnel Zone Obstructions As a matter of practice, 60 percent of the first Fresnel zone must be clear of obstructions (0.6 x F) to allow a clear, unobstructed RF path. Remember, the first Fresnel zone calculation is only one parameter determining path quality. Earth Curvature As the distance of a communication link increases, the clearance problem is compounded by the earths curvature. Radio waves traveling through typical atmospheric conditions bend slightly, MDS 05-6399A01, Rev. G MDS Master Station 131 which is represented by treating the earth as though it were slightly flatter than it actually is. Ex-

perience has shown that if we consider the earths radius 4/3rds of its actual size, we get good agreement between theory and measured propagation results. The figure below shows a representation of the 4/3 earth radio horizon. This figure shows that under normal radio propagation conditions, a station with its antenna 15 meters above flat terrain will have a radio horizon approximately 15 kilometers away, well beyond the visual horizon. Figure 9-2. Antenna Height vs. Theoretical Radio Horizon Fade Margins Variations in the temperature and humidity of the atmosphere with elevation cause the signals to bend more or less, resulting in fading at the receiver. The longer the path, the more likely that deep fades will occur, hence the greater the fade margin required. Different parts of the world have differing propagation conditions, which can be categorized as favorable, average, or adverse. In general, mountainous areas have favorable propagation condi-

tions, while tropical areas and those near large bodies of water have adverse conditions. Calculating Path Loss Assuming that we have satisfied the line-of-sight and first Fresnel zone clearance requirements, we can calculate the path loss. At 450 MHz, the loss between two isotropic radiators (0 dBi an-

tennas) that are 1 km apart is 86 dB. For every doubling of distance, the loss increases by an ad-

ditional 6 dB. Knowing this, the output power (+37 dBm), and the receiver sensitivity, we can calculate antenna size and tower height requirements to cover any desired distance.

eration of the Master Station. While some entries may not appear specifically in the text of this manual, they are included to promote a more complete understanding of wireless data networks, both of current and legacy design. Active MessagingThis is a mode of diagnostic gathering that may interrupt payload system polling communications (contrast with passive messaging). Active (or intrusive) messaging is faster than passive messaging because it is not dependent upon the RTU polling cycle. Antenna System GainA figure, normally expressed in dB, representing the power increase resulting from the use of a gain-type antenna. System losses (from the feedline and coaxial con-

nectors, for example) are subtracted from this figure to calculate the total antenna system gain. BERBit Error Rate. BitThe smallest unit of digital data, often represented by a one or a zero. Eight bits (plus start, stop, and parity bits) usually comprise a byte. Bits-per-secondSee BPS. BPSBits-per-second. A measure of the information transfer rate of digital data across a com-

munication channel. Bridging(see Ethernet Bridging). ByteA string of digital data usually made up of eight data bits and start, stop and parity bits.

MDSSDM41 QuickStartGuide(x790Mode) Figure 2 shows a chassis with card cage and backplane that this module would be typically installed in. The backplane provides the 24V power connection to this unit and provides the customer data interfaces through the card edge connector on the rear of the SDM4-1. 1.0 INTRODUCTION The MDS SDM4-1 transceiver (Figure 1) is a software-configurable, industrial Master Station solution for use in wireless telemetry applications. In this guide, the term SD is used for information common to all models of the radio. This radio module is designed for use with a card cage and backplane similar to that shown in Figure 3, and to be used with a variety of data control equipment such as remote terminal units (RTUs), programmable logic controllers

(PLCs), flow computers, and similar devices. Data interface connections may be made by both serial

(RS-232/485) and limited Ethernet protocols. Figure 2: Typical Orbit MPRS Master Station Chassis. The SDM4-1 modules may be installed in any free peripheral slot of this chassis. Figure 3 shows a typical installation of the radio. NOTE: Retrofit Kits are available to simplify installation at former MDS x710 digital and analog sites. Consult the Reference Manual for ordering details. Invisipbllhaeoc led er Figure 1. MDS SDM4-1 Data Transceiver 1.1 About This Guide This guide covers SDM4-1 transceivers operating in x710-Compatible Mode. All GE MDS manuals are available free of charge at www.gemds.com. Invisipbllhaeoc led er 2.0 INSTALLATION There are three main requirements for installing the transceiver:

Adequate and stable primary power An efficient and properly installed antenna system Correct interface connections between the transceiver and the data device. Figure 3: Typical Master Station Chassis with SDM4-1 radio card installed. NOTE: Chassis has antenna connection in rear, with power and data connections in the front. 2.1 Installation Steps 1. Install the transceiver into chassis as shown in Figure 2. NOTE: To prevent damage to the SDM4-1 radio, wear a wrist strap to prevent ESD discharge to the card edge connector. Also, dress all cables as required to prevent moisture from running along the cables and into the radio. MDSSDM41 QuickStartGuide(x790Mode) For Telnet, connect to the radio with a PC that is on the same IP network as the transceiver. Launch a Telnet program, and connect to the radio using its programmed IP address for the Transmitter and Receiver. The default IP address of the Transmitter configuration is 192.168.1.1. The default IP address of the Receiver configuration is 192.168.1.2. If you do not know the IP address of the radio, use the serial configuration steps below to view the address with the IPCONFIG command. 1. With a PC connected to the COM1 serial port, launch a terminal program, such as HyperTerminal

(included with most pre-Windows7-based PCs) and set the following parameters: 8 bits, no parity, one stop bit (8N1), flow control disabled, VT100 emulation. The COM port automatically finds the connected baud rate (within 1200115200 bps). 2. Press the ESCAPE key followed by a series of ENTER keypresses (at 1/2 second intervals) until the

> prompt appears. The radio is now ready to accept commands. 3. Set/verify the RX (receive) and TX (transmit) frequencies. To set the receive frequency, enter RX followed by the correct frequency in MHz

(xxx.xxxxx). Press ENTER . To set the transmit frequency, enter TX followed by the correct frequency in MHz (xxx.xxxxx). Press ENTER. 4. The factory default modem settings support 9600 bps transmission in a 12.5 kHz bandwidth channel. Many other options are available. The current setting may be viewed using the MODEM command. Use MODEM [xxxx] if changes are required. When finished with the steps above, review the other configuration options to determine if other settings are required for your system. Table 3 lists key software commands for the radio. 2.2 Initial Checkout In-service operation is completely automatic. The only operator actions required are to apply DC power and observe the LEDS for proper indications. Table 1 on the following page summarizes the radios LED functions. 2. Install the antenna and feedline. The antenna used with the radio must be designed to operate in the radios frequency band, and be mounted in a location providing a clear path to the associated station(s). At Remote sites, aim directional antennas toward the Master Station. Low loss coaxial feedline should be used and it should be kept as short as possible. 3. Connect the data equipment. Connection may be made to the COM port using Serial protocols (RS-

232/RS-485). RJ45 to DB9/DB25 adapters may be required depending on physical data port connector type used on the data telemetry device to be attached as shown in Figure 3. 4. Connect primary power to the Orbit MPRS Chassis. Input power must within the ranges specified for the power supply module installed in the Orbit MPRS chassis:

12VDC, 24VDC, 48VDC, 125VDC, or 90-264VAC. These supplies all convert incoming power to +24V for SDM4-1 Module operation. 5. Set the radios configuration. Connect a PC to the radios COM1 and COM2 ports as shown in Figure 4. A straight-thru cable may be used for this connection with an RJ45 to DB9 adapter. NOTE:

Consult your System Administrator if you are unsure of the settings required for your network. Figure 4. Setup for PC Configuration 2.1.1 Software Configuration There are two methods for communicating with the radio for configuration and management: Serial

(COM1, COM2 RJ45 connector) and Telnet

(ETHERNET RJ-45 connector). Both present identical functionality and use the same commands, but the method to configure access is different for each. NOTE: Transmitter and Receiver configuration are handled through separate DSP devices, thus two serial ports or two Telnet sessions will be required to handle configuration of these two functions. The focus here is on Serial access, but Telnet may be used by following these additional points, which replace Steps 1 and 2 below:

MDSSDM41 QuickStartGuide(x790Mode) a degree of fade margin. Optimize the RSSI at Remotes by slowly adjusting the direction of the station antenna. Watch the RSSI indication for several seconds after making each adjustment so that the RSSI accurately reflects any change in signal strength. With RSSI reading, the less negative the number, the stronger the incoming signal (i.e., -70 dBm is stronger than -80 dBm). 3.0 TROUBLESHOOTING All radios in the network must meet the following requirements for proper operation. Check these items first when troubleshooting a communication problem:

Adequate and stable primary power Secure cable connections (RF, data and power) A clear transmission path between Master and each Remote An efficient and properly aligned antenna system providing adequate received signal strength. Proper programming of the transceivers parameters The correct interface between the transceiver and the connected data equipment (correct cable wiring, proper data format, timing, etc.) 3.1 LEDs The radios LED indicator panel provides useful information when troubleshooting a system problem. Refer to Table 1 for LED information. 3.2 Event Codes When an alarm condition exists, the transceiver creates a message that can be read on a connected PC by using the ALARM command. Consult the SD Reference Manual for further details. 3.2.1 Types of Alarms Minor Alarmsreport conditions that, under most circumstances, will not prevent transceiver operation. These include out-of-tolerance conditions, baud rate mismatches, etc. The cause of these alarms should be investigated and corrected to prevent system failure. Major Alarmsreport serious conditions that generally indicate a hardware failure, or other abnormal condition that will prevent (or hamper) further operation of the transceiver. Major alarms may require factory repair. Contact your factory representative for assistance. 2.2.1 LED Functions Active Power

Red Flashing (5x-per-second) Alarm Indication ACTIVE: Blue Continuous Transceiver is operational TX: Blue Flashing/Continuous This LED illuminates whenever the transmitter is active RX: Blue Flashing/Continuous This LED illuminates when the receiver squelch has opened 2.2.2 Antenna SWR Check Before placing the unit in final operation, the antenna systems standing wave ratio (SWR) should be checked using a wattmeter suited to the frequency of operation. High SWR (above 2:1) may indicate an antenna or feedline problem, and should be corrected. 2.2.3 RSSI Check (for SD Remotes) Use the RSSI command (received signal strength indication), command to check for adequate signal strength. The radio must be receiving a signal from the associated Master Station (LINK LED on or blinking). In general, signal levels stronger than 80 dBm will provide reliable communication and allow for 4.0 COMMAND OVERVIEW Table 3 lists key software commands for the transceiver. Detailed descriptions are provided in the SD Reference Manual. Commands can typically be used in two ways:

1. The basic command (shown first) may be entered alone to issue a query or execute a simple command. 2. The basic command may be appended with additional arguments (shown in brackets, if applicable) to further define a setting.

To Whom It May Concern:

Manufacturers Declaration for Limited Modular approval for FCC part 90 licensed spectrum and IC RSS-119. FCC ID: E5MDS-SDM4-1, IC: 101D-SDM41 FCC KDB 996369 Modular Approval Checklist:

Modular approval requirement 1. The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with Part 15 limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. Yes, the RF circuitry is shielded on the PCB Yes 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. 3. The modular transmitter must have its own power supply regulation. This is intended to ensure that the module will comply with Part 15 requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. Yes, the Data is buffered through communication drivers to the processors No (*) 4. The modular transmitter must comply with the antenna and transmission system requirements of 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). The professional installation provision of 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)). 6. The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains Transmitter Module FCC ID:

XYZMODEL1 or Contains FCC ID: XYZMODEL1. Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. Yes, this is a 2 position polarized SMB FAKRA connector. To be only used in our host. Yes, the module was tested on the bench outside of the enclosure as a stand-alone device and complies with Part 15, & 90 emission requirements. Yes, there will be a FCC label on the module and on the host device will be labeled with Contains FCC ID:

E5MDS-SDM4 No, we will control the host integration and DC regulation since this module is only designed to be used in the GE MDS Master Station Modular approval requirement 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, RSS-102 and FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance in accordance with Section 15.247(b)(4). Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance. IC RSP-100, 7.3 Modular Approval Checklist:

Modular approval requirement a) The radio elements shall have the radio frequency circuitry shielded. Physical / discrete and tuning capacitors may be located external to the shield, but must be on the module assembly. b) The module shall have buffered modulation/data input(s) (if such inputs are provided) to ensure that the module will comply with the requirements set out in the applicable RSS standard under conditions of excessive data rates or over-modulation. c) The module shall have its own power supply regulation on the module.
