MDS 05-4846A01, Rev. G SD Series Technical Manual 1 Authorization Features Some features of the radio are dependent on purchased options and applicable regulatory constraints. A key icon is shown near the heading of any such features. In some cases a feature upgrade may be available. Contact your sales representative for additional information. 2 SD Series Technical Manual MDS 05-4846A01, Rev. G 2.0 PRODUCT DESCRIPTION The transceiver is a software-configurable, industrial radio for use in licensed data acquisition networks. It may be interfaced with a variety of data control equipment including remote terminal units (RTUs), pro-
grammable logic controllers (PLCs), flow computers, and similar devices. Data interface connections may be made for both serial
(RS-232/RS-485) and Ethernet protocols. It is designed for use in both polled networks and report-by-exception (push) systems. The radio employs digital signal processing (DSP) technology and a fully digital transmit and receive IF chain to provide robust communica-
tions even under adverse conditions. DSP technology also helps elimi-
nate the effects of component variations or temperature changes, resulting in optimized performance. 2.1 Front Panel Connectors and Indicators Figure 2 shows the transceivers front panel connectors and indicators.

G SD Series Technical Manual 3 2.2 Key Product Features The transceiver is designed to meet the demanding needs of todays wireless networks in a compact, and rugged package. It offers an array of features in a single hardware platform:
Software-configurable via a built-in Device Managerno man-
ual controls or adjustments. Media Access Control (MAC) to prevent data collisions when two or more radios try to use the radio channel at the same time. Available encryption of payload data (AES 128-bit) Supports Virtual LAN (VLAN) operation Terminal Server capability to enable IP addressing of serial interface ports on individual radios Store and Forward capability Supports a wide variety of modem speeds and bandwidths for reg-
ulatory compliance in virtually all regions of the world Ethernet & serial interfacesideal for migration to IP networks Dual serial functionality (RS-232 and RS-485) Over-the-air reprogramming of remote unitsno unnecessary trips to radio sites Licensed 5-watt design, maximizes communications range with low interference risk from other users Configurable via software as a Remote or a Master unit Low power sleep modeideal for battery-powered solar sites Virtual Radio Channels (VRC) support multiple polling applica-
tions on one radio NOTE: Some features may not be available on all units, depending on the options purchased and regulatory constraints for the region in which the radio will operate. 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 band-
width, half duplex radio networks such as those commonly used in licensed telemetry systems. When the MAC is enabled, it provides effi-
cient 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. The main objective of the MAC is to coordinate channel access for all radios in the network, preventing 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 Coordination of Channel Access 4 SD Series Technical Manual MDS 05-4846A01, Rev. G Data Validation of the RF network. Remotes request 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. Additionally, the MAC validates all messages and purges corrupted data from the system. Successful delivery of data is ensured through the use of retries and acknowledgements. Minimal overhead is used to accom-
plish these tasks, which translates to increased bandwidth efficiency of the radio channel with minimal latency, ensuring that messages are delivered in a timely manner. VLAN Capability A Virtual Local Area Network (VLAN) is essentially a limited broad-
cast domain, meaning that all members of a VLAN receive broadcast frames sent by members of the same network, but not frames sent by members of a different network. The radio supports port-based VLAN at the Ethernet interface and over the air, according to the IEEE 802.1Q standard. When VLAN Mode is enabled, the wireless ports of both AP and Remote radios act as a trunk port to carry data. Terminal Server Capability The units Terminal Server option allows serial port data to be sent over the air in the form of IP packets. It works by encapsulating data from the serial (COM1/COM2) ports as IP packets, then transmitting it over the air. At the receiving end, the data is decapsulated and delivered to the appro-
priate COM port. See Terminal Server COM1/2 Configuration on Page 56 for more information. Store and Forward Capability Store and forward (SAF) capability is available in Packet w/MAC mode. It allows a radio to store up incoming data, and retransmit it a short time later to other stations. This can be used to link outlying remote stations to the AP when direct communication is not possible due to terrain, dis-
tance, or other obstructions. Communication routes are automatically discovered and traffic is intel-
ligently filtered so that only store and forward traffic is sent through the SAF unit, conserving critical bandwidth in your network. MDS 05-4846A01, Rev. G SD Series Technical Manual 5 2.3 SD Model Offerings The radio is offered in three model types, using one hardware platform:
EthernetAll SD features and functionality StandardAll SD features, except over-the-air Ethernet data x710Direct, drop-in compatibility for networks using a mix of SD and older MDS x710 radios Model Number Codes The units complete model number is printed on the bottom label. Addi-
tional unit details are available through the Device Manager, described later in this manual. Standard Modes
(Modes covered by this manual) x710 Mode:
Different Manual Required 2.4 Operating Modes and Applicable Manuals In addition to the model offerings above, the radio may be configured to operate in any of the following modes:
Packet ModePayload data from the radios serial and Ethernet ports is assembled into packets and transmitted over the air. Packet mode supports Ethernet Bridging, AES 128-bit encryp-
tion, and Virtual Radio Channels (VRC). This mode requires an all-SD radio network. Packet w/MACThis mode is similar to Packet Mode above, but adds a Media Access Control (MAC) layer to the feature set. The MAC provides robust collision avoidance, with an AP con-
trolling which unit can access the communication channel, and when, for maximum efficiency of the radio channel. This mode supports push traffic, data retry, and store and forward operation. This mode requires an all-SD radio network. Transparent ModeThis mode is over-the-air compatible with MDS x710 transceivers, while supporting payload data encapsu-
lated in IP at the Ethernet port. This mode is ideal for mixed net-
works containing SD and older MDS x710 radios. It allows currently deployed x710 networks to add support for Ethernet data at either the master or remote radios. Note that Ethernet Bridging is not supported in this mode. x710 ModeThis mode provides direct, drop-in compatibility with MDS x710 (4710 or 9710) transceivers, and uses the same core command set as these radios. It is designed for use in systems containing a mix of newer SD radios and legacy MDS x710 units. IMPORTANT: This manual does not cover x710 Mode opera-
tion. Refer instead to the following manuals for x710 instruc-
tions:

MDS 05-4846A01, Rev. G SD Series Technical Manual 7 The SDxP is a tabletop or rack-mount unit designed to hold two trans-
ceivers, two power supplies, and a switchover logic board that automat-
ically selects between transceiver A or B as the active unit. Manual selection may also be made using a front panel switch. Invisible place holder Figure 4. Protected Network Station With two transceivers and two power supplies installed, the unit con-
tinues to communicate even if a failure occurs in one of the transceivers, or its associated power supply. This capability is important in critical applications where uninterrupted service is required. Refer to publica-
tion 05-4161A01 for detailed information on this product. Dual Protected Configurations Two dual transceiver configurations are offered for the SD Series. They are known as the SDxDT and the SDxDP. These configurations are used for the following purposes:
When full duplex operation is desired using dedicated Transmit and Receive transceivers. When a Master or Repeater site requires bandpass duplexers due to the presence of co-located antennas. When streaming Repeater operation is desired using dedicated Transmit and Receive transceivers SDxDT Configuration The SDxDT uses the same chassis as the SDxP described above. How-
ever, one radio is configured with the transmit frequency and the other for the receive frequency, with appropriate connections between them. It also includes a bandpass duplexer tuned to a specific frequency for simultaneous transmission and reception (full duplex) operation. Note that the SDxDT provides one serial port and one Ethernet port for user equipment. 8 SD Series Technical Manual MDS 05-4846A01, Rev. G SDxDP Configuration The SDxDP is a protected, full duplex Master or Repeater site configu-
ration. This consists of two SDxP chassis described earlier, with appro-
priate interconnect cabling between the units. The radios in one SDxP are configured with the transmit frequency and the radios in the other are configured with the receive frequency. The SDxDP also includes a bandpass duplexer tuned to a specific frequency for simultaneous trans-
mission and reception (full duplex) operation. MDS 05-4846A01, Rev. G SD Series Technical Manual 9 3.0 TYPICAL APPLICATIONS This section describes common scenarios the transceiver may be used in. A number of variations are possible; If you have unique requirements not found here, it is recommended that you consult a support specialist at GE MDS. Contact information is provided at the back of this manual. 3.1 Operating Parameters The transceiver can operate in both poll-response and push communi-
cation/report-by-exception networks. In poll-response networks a cen-
tral Master unit communicates with a number of Remote radios one at a time. The Master exchanges data with the currently-connected Remote, and when finished, it establishes a new connection with the next Remote in the polling order. In push communication/Report by Exception net-
works, a Remote can also transmit if it has data to send, typically prompted by a change in status conditions from connected data equip-
ment. The radio includes a number of parameters which may be set to suit the requirements of a particular application. Table 2 provides a summary of common applications, protocols, and radio modes used. Refer to the table to determine what applications can be supported and the required radio mode settings. Table 2.

Other variations are possible, and if you have questions about a specific application not covered here, you may contact your fac-
tory representative using the information at the back of this guide. For typical radio settings in these systems, refer to Table 2 on Page 10. Multiple Address Systems (MAS) This is a common application for the transceiver. It consists of a central master unit and several associated remote units as shown in Figure 5. An MAS network provides communication between a central host com-
puter and remote terminal units (RTUs) or other data collection devices in the field. Often, such a system is used to carry telemetry data to and from widely separated remote radios. Typical MAS applications may be for automatic, remote monitoring of gas wells, water tank levels, electric power distribution systems, and similar control and measurement functions.

Typical MAS Point-to-Multipoint Network Point-to-Point System Where permitted, the transceiver may also be used in a point-to-point arrangement. A point-to-point system consists of just two radiosone Master and one Remote (see Figure 6). It provides a simplex (or half-duplex) communications link for the transfer of data between two locations.

Typical Point-to-Point Link IP/Ethernet Polling and Terminal Server Operation Modern data/control networks often employ IP/Ethernet connectivity throughout the system. The transceiver is well suited to provide connec-
tivity between such sites using its RJ-45 modular connector on the front panel and enabling Ethernet Bridging capabilities. Figure 7 shows an overview of such a system. Note that the Remote radio on the right side of the illustration uses a serial connection. The radios Terminal Server feature allows direct IP/addressing of serial ports on selected radios.

G This type of network can also be used for general Ethernet bridging as supported by the over-the-air bandwidth of the system. Bridge filters in the radio may be set to reduce Ethernet traffic over the RF channel, and improve performance. Port Sharing with Multiple Hosts The transceiver allows for several external data networks to use the same RF network without confusing the data streams. In such a system, multiple host computers at the Master Unit poll their respective RTUs, which may be alone or co-located at the Remote sites. Figure 8 shows an example of such a system. In this case, two host computers (Host A and Host B) are connected to the Master Unit via the applicable data ports. At the Remote sites, serial and Ethernet-based RTUs are employed, and responding to a specific host computer. In the case of the Remote shown on the lower right side of the figure, two RTUs are co-located, but responding to different host computers and handling entirely different data streams. The radio eliminates the need for an external adapter or special external configuration and handshaking when multiple host systems are con-
nected to the network. The radio automatically controls access to the RF channel by multiple hosts when Packet w/MAC is activated. Virtual Radio Channels (VRCs) are used to separate serial data streams on COM2, COM1, or IP payload ports. Packet With MAC operation pro-
vides Media Access Control. It is the recommended method of operation for port sharing systems. NOTE: An option exists to operate in Packet mode without MAC. However, this Packet mode option should only be used for systems that use legacy methods of collision avoidance including Multihost and Listen Before Transmit (LBT). The mode Packet with MAC provides superior performance and better network reliability, collision avoidance and better overall throughput. See corresponding sections of this manual for more information on Packet mode options. MDS 05-4846A01, Rev.

Multihost Arrangement Using Packet w/MAC Mode Push Communication (Report-by Exception) Push Communication, sometimes referred to as Report-by-Exception
(RBE), differs from polled response in that a remote radio normally transmits only when it has data to send. It does not depend on polling from a master radio to initiate transmission. Some typical characteristics of push communication systems are as follows:
Remotes transmit asynchronously May contain large amounts of data Buffering and flow control are used DNP3 and IEC 104 are examples of protocols that implement push com-
munication. Note that both the serial and Ethernet versions of DNP3 support push communication. IP Polling of Serial Remotes The transceiver is ideal for use in systems employing a mix of serial and Ethernet protocols. While many variations are possible, Figure 9 shows a typical arrangement with an Ethernet host at the Master Unit that is polling serial-based RTUs at Remote sites. 14 SD Series Technical Manual MDS 05-4846A01, Rev. G In this example, the Host Computer is connected directly to the radios Ethernet port, and the RTUs at the Remote sites are connected to the transceiver via the radios COM2 serial data ports. The IP Payload fea-
ture, used at the Master, efficiently passes TCP payload over the air, and eliminates the need for an external terminal server. (COM1 may also be used for payload data if properly configured via the menu system. See next example.) Invisible place holder Ethernet Data Port Menu MASTER RADIO

IP Polling of Serial Remotes Serial Remotes with Two Serial Ports In some cases, it is necessary to poll more than one RTU at a Remote site. Figure 10 shows an example of such a system. Here, two RTUs are connected to each Remote transceiver, both using the radios serial portsCOM1 and COM2. By default, the radios COM1 port is configured for serial management functions with a connected PC, but it may be configured for data service using the menu system. This arrangement allows two telemetry net-
works to share a single radio system. MDS 05-4846A01, Rev. G SD Series Technical Manual 15 Packet w/MAC is the recommended method of operation when both serial ports are used to pass payload data if there are two hosts (e.g., Port Sharing with multiple host case). If there is a single host polling all units, packet or transparent mode is the preferred option (depending on whether encryption is required or not) even if there are two RTUs con-
nected to a Remote radio. Device Settings Screen Radio Mode: Packet w/MAC MASTER RADIO To Ethernet Port HOST COMPUTER

Careful planning will help achieve optimal performance from the transceiver. After reviewing this section, refer to the step-by-step installation procedures beginning on Page 26. Figure 11 shows a typical station arrangement. The specific details at an instal-
lation site may vary, but there are three main requirements for installing the transceiver in all cases:

Also, dress all cables to prevent moisture from running along the cables and into the radio. Optional DIN Rail Mounting The unit may be mounted with an optional 35 mm DIN Rail Mounting Bracket Kit (Part No. 03-4125A04). Equipment cabinets and racks of modern design often employ this type of mounting. Once the DIN bracket is attached to the radio, it allows for quick installation and removal of the radio from its mounting rail without the need for tools. The DIN Rail bracket attaches to the units case as shown in Figure 13. The entire assembly then attaches to the mounting rail. 18 SD Series Technical Manual MDS 05-4846A01, Rev. G Step 1: Attach the bracket using the two screws provided. (Attach to the end opposite the units connectors.) Step 2: Clip the assembly onto the DIN Rail. Removal is performed by pulling down on the Release Tab. Figure 13. Attachment & Mounting of DIN Rail Bracket
(Unit shown is for example only, and is not an SD Transceiver.) Release Tab 4.2 Antennas and Feedlines Antennas The transceiver 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. Connection is made to the radio via a TNC coaxial con-
nector. A directional Yagi (Figure 14) or corner reflector antenna is generally used at remote sites to minimize interference to and from other users. Antennas of this type are available from several manufacturers, including GE MDS. Contact your factory representative for details. Invisible place holder Figure 14. Typical Yagi Antenna (mounted to mast) 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. MDS 05-4846A01, Rev. G SD Series Technical Manual 19 The three tables below show the approximate losses that will occur when using various lengths and types of coaxial cable in the 200, 400 and 960 MHz bands, respectively. Regardless of the type used, the cable should be kept as short as possible to minimize signal loss. Table 3.

The supply must be capable of providing at least 2.5 Amperes continuously. NOTE: Early SD4 models supported 10.5 to 16 Vdc power, not 10 to 30 Vdc. Always check the labeling above the power connector to confirm the operating range for your unit. 20 SD Series Technical Manual MDS 05-4846A01, Rev. G A power connector with screw terminals is provided with each unit (see Figure 15). Strip the wire leads to 6 mm (1/4 inch) and insert in the wire ports, tightening securely. Be sure to observe proper polarity as shown in Figure 15. Invisible place holder Lead Binding Screws (2) Wire Ports (2)
(Polarity: Left +, Right ) Retaining Screws (2) Figure 15. DC Power Connector (P/N 73-1194A39) NOTE: The radio is designed for use in negative ground systems only. 4.4 Grounding Considerations To minimize the chance of damage to the transceiver and connected equipment, a safety ground (NEC Class 2 compliant) is recommended which bonds the antenna system, transceiver, power supply, and con-
nected data equipment to a single-point ground, keeping all ground leads as short as possible. Normally, the transceiver is adequately grounded if the supplied flat mounting brackets are used to mount the radio to a well-grounded metal surface. If the transceiver is not mounted to a grounded surface, it is rec-
ommended that a safety ground wire be attached to one of the mounting brackets or a screw on the transceivers case. The use of a lightning protector is recommended where the antenna cable enters the building; Bond the protector to the tower ground, if pos-
sible. All grounds and cabling must comply with applicable codes and regulations. 4.5 Ethernet Data Interface (RJ-45) The transceivers Ethernet Port is used to connect the unit to another Ethernet device. The port has built-in MDIX (auto-sensing) capability, allowing either a straight-through or crossover cable to be used. Figure 16 and Table 6 show pinout data for the Ethernet port. 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 (COM1) methods or Telnet. Web-based management is the preferred and primary means of accessing the transceiver through the built-in Device Manager. MDS 05-4846A01, Rev. G SD Series Technical Manual 21 Telnet may also be used on this connector, and provides the same menu-based user interface available via COM1. If you wish to use Telnet for radio control, refer to the SD Serial/Telnet Management Supplement, Part No. 05-6193A01. Various options are available for passing Ethernet data on this con-
nector, allowing system administrators to optimize the configuration for maximum narrowband efficiency, based on the operating characteristics of their system. 8 1234567 Figure 16. Ethernet Port (RJ-45) Pinout

High Low High Low 4.6 Serial Data Interfaces COM1 and COM2 on the front panel serve as the serial interface ports for radio management and payload data, respectively. The following sec-
tions identify the pin functions used on each interface. These ports are user-configurable for specific applications. The procedures for changing their default operation are provided later in this guide. NOTE: 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 avail-
able from several manufacturers, including GE MDS. COM1 (Serial) Connection The default factory settings for the radios COM1 port (Figure 17) assigns it for management or diagnostics of the radio via a serial connec-
tion to a PC. COM1 may be used to set basic parameters such as output power, modem type and operating frequency of the radio, using text commands. 22 SD Series Technical Manual MDS 05-4846A01, Rev. G COM1 management provides an alternative to the web-based SD Device Manager, accessible via the Ethernet RJ-45 port (see Page 21) when Ethernet connectivity is not available.

ceiver. Refer to INSTALLATION PLANNING on Page 17 for addi-
tional details, as required. 1. Mount the transceiver. Attach the mounting brackets to the bottom of the transceiver case (if not already done), using the four 6-32 x 1/4 inch (6 mm) screws supplied. Mounting bracket dimensions are shown in Figure 12 on Page 18. Secure the brackets to a flat, grounded surface. (If a grounded surface is not available, run a separate ground wire to the transceiversee Grounding Considerations on Page 21.) 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 sta-
tion(s). At Remote sites, aim directional antennas toward the master unit. 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 using IP/Ethernet signaling, Serial protocols (RS-232/RS-485), or both. If an Ethernet device is to be used, connect it to the front panel ETHERNET port to the right of the PWR connector. If a serial device is to be used, connect it to COM2 on the front panel. The radio is hardwired as a DCE device. A straight-through cable may be used in most applications. NOTE: Do not connect the radios Ethernet port to a LAN with high traffic levels. Excessive traffic will overload the port and cause it to be temporarily disabled. In general, traffic levels above 4 Mbps are likely to cause port shutdown. (Traffic limit is less than 4 Mbps with packet sizes smaller than 64 bytes.) 4. Connect primary power. Input power must be within 10.0 to 30 Vdc and capable of providing at least 2.5 Amperes. (Note that some older SD4 radios only allow a 10.5 to 16 Vdc range. Always verify the voltage range by checking the label above the power input socket.) A power connector with screw-terminals is provided with the unit
(see Figure 15 on Page 21). Strip the wire leads to 1/4 inch (6 mm) and insert them into the wire ports. Be sure to observe proper polarity. Tighten the binding screws securely. 26 SD Series Technical Manual MDS 05-4846A01, Rev. G CAUTION POSSIBLE EQUIPMENT DAMAGE The unit is designed for use with negative-ground sys-
tems only. The power supply should be equipped with overload protection (NEC Class 2 rating), to protect against a short circuit between its output terminals and the radios power connector. 5. Configure Basic Settings. Connect a PC to the radios Ethernet connector. Access the radios Device Manager through the PCs browser. On a factory default radio, the Device Manager automati-
cally starts the Basic Setup Wizard. The wizard steps you through the essential radio settings in streamlined fashion. Detailed steps for starting configuration of the radio are presented in Section 5.1 below. 5.1 Initial Configuration This section describes setup of the radio for its first on-air operation. A full description of operating settings is given in Section 6.0 on Page 34. Web-Based Management The Device Manager is the recommended method for user management. It is a built-in software tool that works with your PCs browser to pro-
vide an intuitive, web-style presentation of all radio information, set-
tings, and diagnostics. The Device Manager also contains a wizard function to assist in set-
ting up a radio with a minimum of user actions. Web management uses the radios ETHERNET RJ-45 connector. See Web Browser Connec-
tion on Page 28 for details. NOTE: Web access must be enabled via the Device Security Screen before using this feature. This is the default setting on a factory supplied radio. If changes are needed, check/activate by logging into the Device Security Screen. See your Network Administrator for further assistance. Alternative Management Methods The following methods are for use where web-based management is not available:
Serial(COM1 DB9 connector). This is the console terminal method of control commonly used on earlier GE MDS radios. Telnet(ETHERNET RJ-45 connector). Telnet offers essentially the same capabilities as Serial control, but may be performed either through a local connection, or over a network. MDS 05-4846A01, Rev. G SD Series Technical Manual 27 For more information on alternative management methods, refer to the SD Serial/Telnet Management Supplement, Part No. 05-6193A01, avail-
able from the GE MDS website at www.gemds.com. Web Browser Connection The remainder of this section describes connection and use of the radios built-in Device Manager. To connect to the radio and manage it via the Device Manager, you will need the following:
Requirements A PC with a web browser program installed. An Ethernet cable connected between the PC and the radio as shown in Figure 21. (Alternatively, a network connection may be used, as long as the radio can be reached via its IP address.) The radios IP address. Check with your Network Administrator, or determine the address via a serial/console connection (see Starting Information Screen). The default address for a factory supplied radio is 192.168.1.1. The user name and password for the radio. Check with your Net-
work Administrator, or, if a username and password have not been set, use the factory defaults of admin for both entries. (For security, a new password should be established as soon as possi-
ble after login.) Invisible place holder Transceiver PC Running Web Browser RJ-45 to Ethernet Port Logging On 1. Connect the radio to a PC via an Ethernet connection. Figure 21. PC Connection to Radio for Web Management 2. Configure your PC network settings to an IP address on the same subnet as the radio. The default subnet mask is 255.255.255.0. 3. Enter the radios IP address in a web browser window, just as you would enter a website address. When the login screen appears
(Figure 1), enter the User Name and Password for the radio. The default entries for a new radio are both admin. Click OK. 28 SD Series Technical Manual MDS 05-4846A01, Rev.

nection to a new factory shipped radio. It may also be started manu-
ally by selecting Setup Wizards>>Basic Setup, and then clicking Start. The Wizard displays a series of screens with key selections as fol-
lows:
TX/RX Frequencies RF Output Power Radio Mode Modem Type Com 2 Port Baud Rate Bridge Mode Encryption Mode Device Type NOTE: TX and RX frequencies may not be set when the radio is shipped from the factory, depending on ordering options. If no frequencies have been set, an alarm condition is generated and the PWR LED flashes. These will be cleared after the frequen-
cies are set. In all cases, users must verify that the frequencies are properly set according to the station license. NOTE: Operation on exact multiples of 25 MHz is not supported by the SD4 transceiver (i.e., 400, 425, 450, 475, and 500 MHz). Continue through each wizard screen until all selections have been made. (You may back up to previous screens if required, to review or change settings.) If you are unsure about a required setting, contact your Network Administrator for assistance. MDS 05-4846A01, Rev.

When finished, log out of the Device Manager by clicking Logout in the upper right hand side of the screen. 5.2 Initial Startup & Checkout In-service operation of the transceiver is completely automatic. Once the unit has been properly installed and configured as described above, operator actions are limited to observing the front panel LED indicators for proper operation. If all parameters are correctly set, operation of the radio can be started by following these steps:
1. Apply DC power. Unit must be powered on 2. Observe the LED status panel for proper indications (Table 10). 30 SD Series Technical Manual MDS 05-4846A01, Rev. G 3. If not done earlier, refine the antenna heading of the station to maxi-
mize the received signal strength (RSSI) from the Master Unit. The Maintenance & Status>>Performance screen may be used to observe RSSI. Turn the antenna heading slowly so that the RSSI display can be updated. NOTE: The RSSI facility limits the maximum displayed signal strength to 60 dBm. Invisible place holder Table 10.

The settings below should be reviewed and changed as necessary to suit your particular application. Modem Type Setting All radios in the network must be set to the same modem type and speed. A range of values is available. The default setting is 9600. This setting may be set/viewed using the Configuration>>Radio>>Basic Settings screen. See Page 41 for details. MDS 05-4846A01, Rev. G SD Series Technical Manual 31 In general, the higher the modem baud rate, the faster the communica-
tion speed over the air. However, it must be remembered that signal strength also plays a role in how fast a transmission may be sent. If sig-
nals are strong, faster speeds are possible. If signals are fair or poor, slower speeds may be needed to achieve the best communication results with the least number of re-transmissions due to errors. Inter-Packet Gap Settings For radios operating in Packet Mode, the inter-packet gap is a timing set-
ting 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 communica-
tions channel. Inter-Packet Gap Settings for COM1 and COM2 are made using the Con-
figuration>>Radio screen in the Packet Settings screen. See Page 44 for details. Baud Rate Setting The higher the baud rate, the faster the communication speed of the serial link connected to the COM port. However, this setting has no direct effect on over-the-air transmission speed. The modem baud rate is set using the Configuration>>Communication Ports>>COM1/2 Port Settings window. See Page 62 for details. NOTE: Baud rate settings that are matched or higher than the modem speed should be used in all cases. Ethernet Settings The local Ethernet connection must be configured to conform to the needs of the local Ethernet network. The Configuration>>Communication Ports>>IP Configuration screen is used to set/view these settings. Here are some general points that apply to Ethernet settings:
The radio's Ethernet settings must be configured in order to com-
municate over the LAN to which it is connected. It must be known whether or not a DHCP server is active in a net-
work to make use of the radios DHCP setting. If DHCP is available, it can be enabled. Once enabled, it can take a few minutes before the radio obtains an IP address, which will be displayed in the Current IP Address field. If DHCP operation is unavailable (or is not desired), then a static IP address may be manually set. IP network setup is beyond the scope of this manual. Consult your network administrator. As a quick reference, a typical LAN setup might appear as fol-
lows:
Static IP Address 192.168.1.101 32 SD Series Technical Manual MDS 05-4846A01, Rev. G Static IP Netmask Static Default Gateway 192.168.1.1 DHCP Disabled 255.255.255.0 See Page 64 for more information on Ethernet settings. Antenna SWR Check Before placing the radio into final service, a check should be made of the antenna systems standing wave ratio (SWR). Use a directional watt-
meter suited to the frequency of operation for this check. High SWR
(above 2:1) may indicate an antenna, connector, or feedline problem, and should be corrected. MDS 05-4846A01, Rev. G SD Series Technical Manual 33 6.0 USING THE DEVICE MANAGER The radio contains a built-in management system known as a Device Manager. This web-based tool is accessed with a PC connected to the radios Ethernet port as shown in Figure 23. It offers an intuitive method for managing your radio and performing common maintenance tasks. NOTE: The Device Manager is the preferred method for managing the transceiver. Menu-based Serial or Telnet management is also possible. Refer to the SD Serial/Telnet Management Supple-
ment, Part No. 05-6193A01 for details. If you are using the Device Manager for the first time, refer to Web Browser Connection on Page 28 for instructions on connecting a PC to the radio and logging into the Device Manager for basic radio setup, including use of the Setup Wizards. Transceiver PC Running Web Browser RJ-45 to Ethernet Port Figure 23. PC Connection to Radio for Web Management 6.1 Navigating the Screens Upon login into the Device Manager, the Overview screen appears as shown in Figure 24. The selection pane at the left side of this screen pro-
vides access to any of the available screens. Simply click an item of interest, and the new screen appears. Sub-level screens are displayed under the main heading, and may be clicked to open them. With a desired screen displayed, simply scroll up or down to reach a required setting or indication. Drop-down boxes or blank fields are pro-
vided for entering new information. Once a new parameter is entered, click Commit Configuration on the right-hand side of the screen to apply the setting, or select Undo to cancel it. 34 SD Series Technical Manual MDS 05-4846A01, Rev. G Invisible place holder Figure 24. Overview Summary Screen Overview Screen The Overview screen (Figure 24) provides a read-only view of all key settings and operating conditions for the radio. The Health & Maintenance Summary, in particular, can help you quickly spot changes in operating conditions. By becoming familiar with expected readings, you can iden-
tify parameters that are outside their normal ranges, and take corrective action. Clicking the Printer friendly configuration label at the bottom of the screen brings up a print-ready report that includes not only the Overview screen, but all settable items and indications. Printing this report and keeping it with the manual provides a convenient way of reviewing the settings for a particular unit at any point in the future. Printout Option Logging Out To exit the Device Manager, click Logout in the upper right hand side of any screen. The session is terminated. NOTE: To maintain security, it is best to log-out of the Device Manager as soon as you are done working with it. If you do not log out, the session automatically ends after 10 minutes of inactivity.

MAC Routes, Page 72 The remainder of this section covers the screens for Configuration, Maintenance, and Status of the transceiver. The emphasis is on available selections, how to access them, and their effect on radio operation. If you are unsure of the setting required for a particular radio in your net-
work, consult your Network Administrator for assistance. View I/O Statistics for COM1, COM2, Ethernet Port, Remote Programming, Ethernet Interface, Data Link Layer, and MAC. View MAC Routes NOTE: The Device Manager screens shown in this manual were obtained from a radio operating in a lab environment and are provided as examples only. Not all content will be legible in these reduced size examples. Also, the parameters and settings shown may differ from those seen in field service conditions. 40 SD Series Technical Manual MDS 05-4846A01, Rev. G 6.3 Configuration Screens The Configuration screen (Figure 25) contains a number of key settings for the radio, including RF parameters, modem selection, packet set-
tings, MAC parameters, and several advanced settings. Individual screens may be selected beneath Configuration on the left side of the screen. Figure 25. Configuration Screen
(Portion of screen shownscroll for additional selections) Radio The Basic Settings screen contains important RF and modem selections for radio operation, as discussed below. Basic Settings RF Output Power (dBm)The RF output power may be set between 20 and 37 dBm (0.1 to 5 watts) in 1 dB increments. The default setting is 37 dBm. Full power is not required in many cases, and lower settings will place less demand on the DC power supply and reduce the chance of interference with other stations. Only the power necessary to carry out reliable communications should be used. MDS 05-4846A01, Rev. G SD Series Technical Manual 41 Modem TypeThis 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 12. The table also lists modem sensitivity ratings for the various modems. Note that some modem choices are limited based on the model purchased. Table 12.

Sensitivity is -104 dBm for SD2 and -100 dBm for SD9. 5) SD1 sensitivity may be up to 2 dB less, due to MDS 1710 interoperability constraints. Transmit/Receive FrequencyThe receive and transmit frequencies may be viewed or set here. If no frequencies have been entered, the fields will be blank and the radios PWR LED will flash, indi-
cating that an entry is needed. 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. 42 SD Series Technical Manual MDS 05-4846A01, Rev. G Device Settings Owner Name/Owner MessageAn owner name and message may be entered for the radio for informational purposes. These are free-form fields which do not affect the operation of the radio in any way. Such fields might be used to identify the network administrator/company name, and include a site-specific message
(i.e., Unit 2 at North Tower site). Up to 30 alpha-numeric characters may be entered (there is no minimum), and any printable charac-
ters may be used. Enable SleepSleep Mode places the transceiver into a hiber-
nated low power state, with a nominal current draw of less than 10 mA (at 13 Vdc). Wake-up time is approximately 50 milli-
seconds. Sleep Mode is often used at battery/solar-powered remote sites to conserve power. An active low on Pin 4 of the COM2 port is what actually puts the radio to sleep. This signal must be supplied by the equipment connected to the radio (i.e., RTU, PLC, etc.). Sleep mode is not intended for use on master radios. COM LED ModeThe behavior of the radios COM/DATA LEDs may be configured using this box. By default, the LEDs show dual port activity (Auto). Four LED modes may be selected as summarized in Table 13. Table 13. COM/DATA LED Modes vs. Behavior LED Mode Selection Serial COM/DATA LED Behavior LED1 Function LED2 Function x710 COM1 Activity COM2 Activity Monitors TXD on COM2 port Monitors any COM1 RX or TX activity OFF Dual Port Activity
(Auto Default) Monitors any COM1 RX or TX activity Monitors RXD on COM2 port OFF Monitors any COM2 RX or TX activity Monitors any COM2 RX or TX activity MDS 05-4846A01, Rev. G SD Series Technical Manual 43 Radio ModeThe radio can operate in one of several modes. The available selections are:
Packet Packet w/MAC x710 (not covered by this manual; See pub. 05-4670A01) Transparent User InterfaceThis parameter selects the method of radio man-
agement for the Serial/Telnet interface. It has no effect on the web interface. The default selection is Menu. Alternatively, you may select CLI, which switches the radio to a Command Line Interface. With this interface, commands are entered in text-based fashion, as described in the SD Serial/Telnet Management Supplement, Part No. 05-6193A01. COM1/COM2 Port Inter-Packet GapTiming setting used to delimit a packet on the serial interface for radios operating in Packet Mode. 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 effectively slow down the communications channel. The Inter-Packet Gap is specified by the number of character times
(the time it takes to send an individual character). Transparent RX Timeout (ms)This setting is similar to the timing parameters for COM1/COM2 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. Packet Settings Media Access Control
(AP menu shown) Device TypeSelects Access Point, Remote, or Store and Forward. An Access Point serves as the Controller of the RF network. Only one radio is configured as an AP. Typically this is the polling master. A Remote is connected to end devices in the field (e.g. PLC, RTU), and there can be any number of these in a network. Each Remote must have a unique Unit Address, however, which 44 SD Series Technical Manual MDS 05-4846A01, Rev. G is set on the Diagnostic Settings screen (see Diagnostic Settings on Page 47). A Store and Forward device is a radio designated to retransmit data to/from an outlying Remote (see SAF Network, below). SAF Network(AP Only) Selects whether or not a Store and For-
ward radio is present in the network (True), or not (False). Store and Forward allows extending the coverage area of a network beyond the primary footprint of the system. This can be used to link outlying Remotes (or Remotes blocked by terrain or other obstructions) into the network. A detailed discussion on using Store and Forward is provided below. Repeater Network(AP Only) This setting must be enabled if the RF network contains a repeater station, or communications will not work. Remotes automatically learn this setting from the AP. Retry CountIf 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 (s)When a message arrives from the payload inter-
face(s) it is time-stamped and queued for radio transmission. If the radio cannot transmit the message before the Time-to-Live
(TTL) value, the message is discarded. This helps prevent stale or old data from being sent over the air. Store and Forward Operation Store and Forward (SAF) operation extends a wireless networks cov-
erage area by electing a device or devices to store data and forward it to a unit (or units) beyond the reach of the primary coverage area. Conven-
tional RF repeaters receive and transmit data simultaneously. They are effective at increasing range with low latency, but they are more expen-
sive, have high power consumption, and require more complex installa-
tion. SAF-designated units act as smart single radio packet repeaters. The SAF feature provides a simple, low cost alternative to range exten-
sion when a traditional repeater isnt desired. Figure 26 depicts a typical single unit SAF network. This network sup-
ports a single SAF hop. Chained SAF hops are not allowed. However, multiple SAF radios are supported provided their RF coverage areas do not overlap, as this would create radio interference and severely reduce throughput. SAF will work in conjunction with repeater assemblies to provide even more extended range. NOTE: Remote radios being served by a Store-and-Forward unit must have their TX/RX frequencies set to match those of the AP/Master station. This allows communication with the SAF radio, which uses standard Remote TX/RX frequencies. MDS 05-4846A01, Rev. G SD Series Technical Manual 45 Invisible place holder Figure 26. Store and Forward System Example Store and Forward is available in Packet w/MAC mode and supports all MAC features including collision avoidance, retries, and acknowledge-
ments. Furthermore, all major radio features are supported in SAF net-
works such as diagnostics, over the air programming, bridging, VRCs, etc. Dual Duty of SAF Remotes: Since an SAF device doubles as a Remote radio it may participate in direct exchanges with the Master/AP. By design, an SAF device is always within the primary coverage area and has direct communication to the AP. Therefore, all SAF devices act as both a standard Remote for direct exchanges, as well as an SAF unit for Store and Forward exchanges. An SAF exchange is defined as any exchange between the AP and a Remote through an SAF device. In all cases, the AP still controls the operation of the network. After sending an SAF data frame, the AP remains idle until the frame has been delivered to the Remote, at which time it will return to direct or SAF operation, depending on the message type (unicast or broadcast). Direct vs. SAF Traffic: Depending on network topology, it is possible for some Remotes to hear both direct polls from the AP and SAF mes-
sages from an SAF-designated Remote. It is more desirable to use the direct traffic to avoid the latency of going through the SAF link, and the radios firmware handles this situation automatically. SAF frames are ignored when the direct path is available. The system is dynamic; if the direct path becomes unavailable for any reason, it quickly switches to the SAF path to provide continued operation. Traffic Routing: Typically, network radios are immobile, but fading may cause paths to come and go. Because of this, the AP device imple-
ments routing to each Remote device. This ensures that only SAF traffic passes through SAF Remotes. Direct traffic is terminated at the local coverage area, keeping efficiency high. The transceiver achieves these steps automatically, and does not require user input. The following is an explanation of how this routing scheme is achieved. 46 SD Series Technical Manual MDS 05-4846A01, Rev. G Initially, all Remote device routes are unknown. The AP assumes that all undiscovered Remotes can potentially be on the SAF link. Once a Remote attempts to communicate upstream to the AP, the AP is aware of the Remote's path based on the exchange type, direct or SAF. The AP stores this information in a database linked to the Remote's address. Future exchanges with the Remote initiated by the AP will reference this database and the AP chooses the most recent exchange type. Upstream, the Remote can freely choose the best exchange type based on what is available at the time. The AP continuously updates the routing database on each exchange to a Remote. If a Remote has not been heard from within a certain time frame, the route is reset to initial conditions so that the route may be relearned. This does not cause any additional delay and is implemented only as a safeguard. This allows for highly efficient and adaptable routing to each Remote device without the overhead of a routing protocol, and saves critical bandwidth. Diagnostic Settings Unit #This parameter identifies the radio in the wireless network with a specific ID during diagnostic sessions. Dlink TypeThis setting identifies the radio as either a Node, Root, Repeater, Peer, or Gate. Each of these are operating modes of the transceiver with respect to diagnostic/management activities.
(See Performing Network-Wide Remote Diagnostics on Page 89 for details.) Dlink StatusThis item is used to enable or disable diagnostics functionality. Setting it to ON configures the radio to pass the diagnostic link protocol (DLINK) over the radios COM1 manage-
ment port. Dlink Baud RateThis setting determines the COM1 serial data diagnostics communication rate in bits-per-second (bps). Dlink TCP AccessThis setting enables DLINK over Ethernet via TCP. This allows an external NMS to manage the radio without the need to dedicate a serial port for this function. Dlink TCP PortThis setting specifies the TCP port for DLINK communication. The address for Ethernet-based DLINK commu-
nication is given by the radio's IP address (from the general set-
tings screen) and the port number specified here. MDS 05-4846A01, Rev. G SD Series Technical Manual 47 Advanced Settings Soft-Carrier Dekey (ms)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 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 equip-
ment. RX Time-Out EnableEnables or disables the RX time-out func-
tion. RX time-out protects against a receiver which fails to receive data for a period exceeding the RX time-out delay setting
(see below). When the time is exceeded, an alarm is issued. The alarm may be used to signal switchover to an alternate unit in redundant systems. The RX time-out is cleared when the radio receives a new Carrier Detect signal. The default selection is OFF
(no RX time limit). RX Time-Out Delay (min)Sets the time delay, after which an alarm is issued when no signals have been received. The default setting here is 1111 minutes. TX Time-Out StatusEnables or disables the TX Time-Out func-
tion. This protects against a transmitter which remains keyed for a period exceeding the TX Time-Out Delay setting (see below). When this time is exceeded, the transmitter is taken offline, pre-
venting disruption of the wireless network. The TX time-out is cleared when the keying source goes away and the radio keys again.The default selection is ON (transmitter shuts down when time limit is reached). TX Time-Out Delay (sec)Sets the time delay, after which a keyed transmitter is taken offline. The default time-out setting is 30 sec-
onds. DatakeyDetermines whether or not the radio is configured to key (transmit) upon receipt of payload data at its interface port. The default setting is ON. RTS KeyDetermines whether or not the radio is configured to key (transmit) upon receipt of an RTS (ready to send) signal at its interface port. The default setting is OFF. 48 SD Series Technical Manual MDS 05-4846A01, Rev. G Push-To-Talk Delay (ms)Allows programming 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 (ms)Allows programming 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. Automatic Freq. CorrectionAutomatic Frequency Correction
(AFC), is used to counteract the slight RF frequency drift that may occur over time or through wide swings of ambient temper-
ature. 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 oper-
ation. The Switched Carrier setting is only for use on radio modems with B suffixes (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 in full-duplex mode only. Master units in B-modem networks will have SWC set to ON regardless of ckey being on or off. RX Signal AttenuationThis setting is intended for use in very strong signal environments (-20 dBm or stronger). It should be kept off when working with normal or weak signal levels. Force DCD to AssertedSome 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. MDS 05-4846A01, Rev. G SD Series Technical Manual 49 Features Bridge Configuration Bridge ModeUsed to enable or disable Ethernet Bridging on the radio. Default setting is OFF. Basic Bridge Filter SelSets the type of bridge filter to be used. Available selections are: Broadcast/Unicast (All), Unicast and ARP, and Unicast Only. Adv Bridge Filter StatusWhen on, this filter bridges the Ethernet traffic received from a specific Ethernet-enabled device matching one of the Adv Src Addr Filter Values (see below). Adv Src Addr Filter ValSets the Advanced SRC Address Filter Values. Four address fields are available. If the Adv Bridge Filter Status is on, and an incoming Ethernet frame src addr matches any of these values, the radio bridges the frame. Otherwise, it is dropped by the radio. The entry format must be xx:xx:xx:xx:xx:xx. VLAN Configuration A VLAN is essentially a limited broadcast domain, meaning that all members of a VLAN receive broadcast frames sent by members of the same VLAN but not frames sent by members of a different VLAN. The radio supports port-based VLAN at the Ethernet interface and over the air, according to the IEEE 802.1Q standard. When VLAN Mode is enabled, the wireless port of both AP and remote radios act as a trunk port. The Ethernet port of an AP radio is normally configured as a trunk port. This type of port expects incoming frames to have a VLAN ID and sends outgoing frames with a VLAN structure as well. The Ethernet port of a Remote radio can be configured as an Access Port or as a trunk port. When the Wireless or Ethernet port (AP or Remote) is configured as an Access Port, the radio tags incoming traffic with a VLAN ID, and strips the tag before sending out traffic. This traffic is known as the Data VLAN. Additionally, a second VLAN is assigned for other traffic that is terminated at the radio, such as Web, Telnet, DLINK over TCP, TFTP reprogramming, etc. This traffic is known as the Management VLAN. Traffic directed to the terminal server or IP payload service should be sent via the Data VLAN. 50 SD Series Technical Manual MDS 05-4846A01, Rev. G When the Ethernet port of a Remote is configured as a VLAN trunk, the radio expects all incoming Ethernet frames to be tagged, and passes through all outgoing frames as received from the wireless link with the unchanged VLAN tag. ModeDefines the Ethernet port as Trunk, Access, or Disable (an untagged port). The default setting is Disable. The mode should be the last parameter changed when configuring the VLAN feature, since any Telnet or web connections will be lost after it is changed. Also, configure the appropriate IP and IP2 settings before changing this parameter. Data IDDefines the VLAN ID assigned to the APs LAN traffic to be delivered to an Access Port, and the terminal server service, or the IP payload service. The ID is used for filtering and tagging purposes. Any valid ID from 1 to 4095 may be entered. The Default Data VLAN ID is 2. Mgmt IDDefines the VLAN ID assigned to the APs LAN traffic that is to be delivered to the radio. Note that traffic for the termi-
nal server and IP payload service is expected in the data VLAN. This ID is used for filtering and tagging purposes. Any valid ID from 1 to 4095 may be entered. The Default Mgmt VLAN ID is 1. Gateway IFDefines the VLAN that contains the default gateway in the radio. Available selections are Mgmt and Data. The default setting is Mgmt. NOTE: The VLAN Mode parameter must be consistent at both the AP and Remote radios in order for data to flow correctly. Failure to do so may result in data not being transported correctly even when the radios are able to communicate over-the-air via an RF link. The transceiver provides a legacy collision avoidance scheme called Listen Before Transmit (LBT). It employs P-Persistent CSMA protocol, which senses channel usage and inhibits transmission if the channel is currently in use. CSMA is an abbreviation for Carrier Sense Multiple Access. This setting is superseded by Packet w/MAC and should only be used in legacy systems and special use cases. Packet w/MAC is the preferred method for collision avoidance. NOTE: The Listen Before Transmit (LBT) feature requires radios to be configured for Packet Mode operation. Packet w/MAC operation provides an alternative method for media access. Listen Before Transmit (LBT) Settings MDS 05-4846A01, Rev. G SD Series Technical Manual 51 Listen Before TransmitUsed to activate or deactivate LBT when this feature is authorized in the radio. LBT BehaviorLBT can be configured to behave in one of two ways; either listen on the radios transmit frequency (TX) or listen on the radios receive frequency (RX). Typically, Remote radios are configured to Listen on RX (the default selection) to avoid col-
lisions with the Master unit. In peer-to-peer configurations, Listen on TX may be preferred. Optimal choices depend on the data trans-
mission characteristics of the connected system. Min/Max Channel Wait (ms)These settings refer to the time period
(in milliseconds) to wait after the channel is free before transmis-
sion is allowed. Minimum wait time: Normally, the minimum channel wait time should not be changed from its default setting of 0 ms unless per-
forming advanced operations, such as staggering the responses from multiple Remotes. Maximum wait time: Normally, this setting should not be changed from its default of 100 ms unless performing advanced operations. Some examples of when this may be beneficial include:
There is a need to stagger responses from several Remote radios. The transmission latency from the time the channel is free is too high, in which case a lower value can be entered. Collisions over the air are too high, in which case a higher value can be entered. NOTE: The lower the value of the Maximum Wait Time, the higher the chances of collisions occurring over-the-air. Conversely, the higher the value of the Maximum Wait Time, the higher the transmission latency. Timeout (ms)Provides a setting for the maximum wait time (in milliseconds) for the channel to become free. When this time is exceeded, the radio follows the action defined in the Packet Action on Timeout setting (either Drop or Send). 52 SD Series Technical Manual MDS 05-4846A01, Rev. G IP Payload Configuration (1/2/3) Packet Action on TimeoutDetermines what to do with a packet once the timeout period has expired and the channel is still not available. If set to Drop, the packet is discarded. If set to Send, transmission of the packet is attempted despite the channel being busy. Clear Channel RSSI (dBm)LBT works by sensing the presence of a carrier signal on the radios operating frequency. If a carrier is present, transmission is inhibited. The Clear Channel RSSI setting allows a threshold to be set which, when equaled or exceeded, declares the channel busy and therefore unavailable for transmit-
ting. This section describes how to setup and configure the radio for exchanging IP/Ethernet Payload data with Remote radios. It is an effi-
cient feature that supports Ethernet connectivity with maximum over-the-air (OTA) efficiency for UDP and TCP data streams. Remote radios receiving the data can then forward this traffic to their serial ports or Ethernet port. This feature is particularly useful for adding Ethernet devices to a mixed system using MDS SD and x710 Transceivers. This feature is different than Ethernet Bridging, which is described on Page 50. NOTE: To make use of this feature, the radio must be properly autho-
rized for Ethernet data. If it is not, contact your sales represen-
tative for further information. It is helpful to understand that IP data is terminated at the radio, yet the payload data is transmitted OTA. As such, the radio acts as a terminal server converting IP data into a serial over-the-air port. In other words, a transmitting radio receives an IP message, strips off the IP headers, and sends it over the air with VRC identification (VRC-1, VRC-2, or VRC-3). A receiving radio may then be set up, for example, to have COM2 or an IP port deliver all VRC-1 traffic. The radio supports Ethernet operation on three IP payload ports. These settings are made on the IP Payload Configuration Menu (1, 2, or 3) as shown in the screen which follows later in this section. In the Master unit only, Multihost may need to be enabled if more than one IP Payload port is required. IP Payload is intended to be used in a poll-response system. An Ethernet device at the Master radio sends UDP/TCP poll messages to the Masters Ethernet port which is configured to listen for data. The poll is sent OTA and a RTU/PLC attached to one of the Remote radios (via serial or Ethernet) responds. The response is sent OTA back to the Master radio. The Master radio then sends the response back to the polling station via Ethernet. MDS 05-4846A01, Rev. G SD Series Technical Manual 53 When configuring this feature, you are notified of the success or failure of the operation. Additionally, Ethernet and OTA statistics can be mon-
itored to inspect the success of the poll-response communication. The following additional points apply to Ethernet payload operation:
To make efficient use of limited bandwidth, this feature trans-
ports the payload content of Ethernet data to be sent over the air. This feature does not bridge Ethernet networks separated by radios. For more information, see Ethernet Bridging found on Page 50. A broadcast poll-response network is assumed, where addressing information is contained in the payload portion of the UDP/TCP messages. NOTE: Screen selections vary depending on the radio mode selected. Three such screens are provided for Payload 1, 2, and 3. StatusEnables or disables the IP Payload port. ModeThe operating mode for the IP port may be set to UDP Socket, TCP Client Socket, TCP Server Socket, or TCP Server/Client Socket to match the service in which it will operate. Talk on/Listen toAny combination of the three Virtual Radio Channels may be entered in these fields. For more information on how VRC settings are used, refer to the SD Serial/Telnet Manage-
ment Supplement, Part No. 05-6193A01. Local Radio IP PortUsed to specify a port number for the RJ-45 modular connector on the radios front panel.

ity. Committing ConfigurationOnce you are satisfied with all of the settings on the screen, you make them active by clicking this but-
ton. The message Changes committed appears at the bottom of the screen to confirm the action. Restoring ConfigurationIn some cases, you may wish to revert to the previous configuration of the screen, prior to any changes being committed. This might be useful if one or more settings were inadvertently changed and you wish to return to a known state. To restore the prior settings, simply click Restore Configura-
tion. Understanding the Use of Virtual Radio Channels (VRCs) The use of Virtual Radio Channels (VRCs) may require additional explanation for new users of the feature. VRCs allow over-the-air data to be directed to specific interface ports (IP or Serial) on the radio. Con-
ceptually, this can be pictured as creating pipes for delivery of data to the desired radio interfaces. 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. NOTE: The Virtual Radio Channel (VRC) feature is only supported in Packet and Packet w/MAC modes. It is not supported in Trans-
parent 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 the COM1/COM2 Settings 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 out, while the Listen to parameter spec-
ifies the VRC(s) for incoming data. Use of these parameters was described earlier in this section. Any combination of the three VRC numbers may be entered in the selec-
tion fields. Figure 27 illustrates the relationship between the VRC set-
tings and the routing of data between units. MDS 05-4846A01, Rev. G SD Series Technical Manual 55 IP Payload 1 Data

Virtual Radio Channel (VRC) Concept Ethernet/IP RTU Serial-Based RTU The radios Terminal Server feature allows IP addressing of the COM1 and COM2 serial interface ports. Data from these ports is sent over the air as encapsulated IP packets. At the receiving end, the data is decapsu-
lated and delivered to the appropriate COM port(s). In contrast to the radios IP Payload feature, having a terminal server at the Remotes means that Ethernet data can be delivered to specific devices connected to these radios. Terminal Server settings, examples, and additional ben-
efits are described in the following paragraphs. The image below shows the Device Managers Terminal Server config-
uration screen. Two such screens are provided in the Device Manager;
one for COM1 and another for COM2. Here, the behavior of the ter-
minal server is set and applied. The Terminal Server must be enabled 56 SD Series Technical Manual MDS 05-4846A01, Rev. G and configured in all radios requiring IP encapsulation of serial data. Proper configuration of the serial ports is also required, using the Com-
munications Ports section of the Device Manager. NOTE: Available selections vary depending on the mode selected. StatusEnables or disables the Terminal Server feature. ModeSets the operating mode for the IP port. It may be set to UDP Socket, TCP Client Socket, TCP Server Socket, or TCP Server/Client Socket to match the service in which it will operate.

Commit ConfigurationClicking this button causes any staged parameter changes to be activated and saved to non-volatile mem-
ory. Unlike most other attributes, terminal server attributes don't automatically take after making a change. Similar to the Ether-
net settings, many items only make sense to change as a block, and this is why the Commit Configuration button is provided. Refresh/AutoClicking the Auto button causes the Web/UI inter-
face to update and load the latest saved data. Clicking Refresh forces an instant update. A periodic refresh update interval is pro-
vided for the Auto parameter. MDS 05-4846A01, Rev. G SD Series Technical Manual 57 The Terminal Server supports the following communication protocols:
Point-to-Point: TCP or UDP Point-to-Multipoint1: UDP (One of the Destination IP Addresses is a multicast IP address) Multipoint-to-Multipoint1: UDP (Two or more of the Destination IP Addresses are a multicast IP address) 1Data from local multicast IP addresses is always delivered to the socket layer by the radio's TCP/IP stack. Therefore, to receive data from local multicast IP addresses, simply set the Local Radio IP Port equal to the destination IP port of the multicast IP packet. Using the Terminal ServerTypical Example The following describes a Terminal Server implementation in a radio network. Figure 28 below is referenced in this discussion. Figure 28. Terminal Server Example IP/Radio Network Setup and Configuration The following conditions are assumed for this example:
Radio (RF) link is good between AP and Remote 1, and AP and Remote 2. IP addresses are properly configured as shown in Figure 28. Packet w/MAC mode is enabled in all radios, and the MAC Device Type is set to AP in radio with the IP address equal to 192.168.1.2. Ethernet Bridge is enabled in all radios. 58 SD Series Technical Manual MDS 05-4846A01, Rev. G Serial Addressability This example shows that it is possible to communicate to specific serial devices (e.g., PC 2 COM1, and PC 3 COM1) over the radio network. Note that TCP is used as the transport layer for communication here, which provides data reliability at the application level. 1.

(Use only if operating in Packet mode without MAC) Figure 34. Remote 2 Terminal Server/COM2 Port Communication 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. The Multihost Settings screen is used only when Packet w/MAC mode is not selected. It provides an alternative way to run multiple host appli-
cations at the master unit, which may be operating on different com-
puters. Multihost operation is described in more detail in the SD Serial/Telnet Management Supplement, Part No. 05-6193A01. MDS 05-4846A01, Rev. G SD Series Technical Manual 61 Packet w/MAC operation replaces multihost operation, and is the rec-
ommended method for passing multiple data streams. See Device Set-
tings on Page 43 for instructions on setting the Radio Mode to Packet w/MAC. Multihost EnableEnables or disables multihost capability. Multihost DelaySets the desired delay time (in ms) for switching between hosts during multihost operation. Communications Ports COM1 Port Settings Startup ModeThe default mode for COM1 is Console when the transceiver is first powered up, but the startup mode may also be set to Data if the port is to be used for passing payload data. Current ModeThe mode setting for the COM1 port may be changed on demand (Console or Data) using this selection. Data Baud RateThe default data rate for COM1 is 115200 bps, but it may be set to any of the following speeds: 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200.

DeviceThis setting controls the device behavior of x710 legacy radios. It does not apply to packet or Ethernet radios, and may be disregarded for these later models. Talk on/Listen toAny combination of the three Virtual Radio Channels may be entered in these fields. For more information on how these settings are used, refer to the SD Serial/Telnet Manage-
ment Supplement, Part No. 05-6193A01 more information. Term Srvr StatusIndicates whether the radios terminal server is enabled or disabled. NOTE: The radio can operate in RS-422 mode when RS-485 is selected. IP Configuration The IP Configuration screens contain various settings for the IP data stream. Each item is listed below along with an explanation of the parameter. Note that the bottom of the screen displays the current set-
tings that have been applied to the radio in a read-only fashion. Current IP AddressRead-only indication of the current IP address programmed. Current Subnet MaskRead-only indication of the subnet mask programmed. Current Default GatewayRead-only indication of the current default gateway programmed. Static IP AddressThe radio requires a local IP address to support remote management and serial device (terminal server) services. An IPv4 IP address should be entered in this field, unless DHCP is enabled, in which case it is not required. 64 SD Series Technical Manual MDS 05-4846A01, Rev. G Static IP NetmaskThis refers to the radios IPv4 local subnet mask. This parameter is used when the radio attempts to send a locally-initiated message, either from the terminal server, or a management process. You do not need to define it if DHCP is enabled. Static Default GatewayThis is the IPv4 address of the default gate-
way device, typically a router connected to the radio. DHCPDynamic Host Configuration Protocol (DHCP) handles the assignment of IP parameters (Address, Netmask, Gateway) to all units in a network, and allows for introducing new devices on the network with minimal manual intervention. The assigned parameters are valid for a specific lease time, at which point they can be reassigned or renewed. Security The transceiver offers a number of safeguards against unauthorized management access and protection of payload data. All of these features are accessed via the security configuration screens. Device Security Local SecurityThis parameter is used to specify whether or not a local log-in is required when using the transceivers menu system. The default setting is Local Login Required, and is appropriate for most circumstances. Setting this parameter to No Local Login Required might be useful in cases where only a small number peo-
ple with administrative duties have physical access to the radio, and need to access the menu frequently. In this mode, the menu operation behaves identically to the Administrator level login. Telnet AccessTelnet access is a powerful feature that allows management of the radio via an Ethernet connection. This may be done locally, using a cable connected to the management PC, or at any distance using an IP/Ethernet network connection. Telnet access is also possible over the air if the Ethernet Bridging feature is enabled. Any user with the IP address of the radio can log in to the unit with this method. Disable Web AccessWeb access to the units Device Manager is normally enabled. Click this item to disable web access. A warn-
ing message appears to confirm disabling of web navigation. MDS 05-4846A01, Rev. G SD Series Technical Manual 65 NOTE: If the radio login password is lost or forgotten, contact GE MDS for assistance. Proof of authorized user is required for a new password, and the radio will revert to its default settings. It is recommended that users periodically export their config-
uration file so that it can be loaded back into the radio if their old one requires replacement. Payload EncryptionWhen on, applies encryption to payload data stream. The default selection is OFF. Dlink SecurityApplies security restrictions to network-wide diagnostic data. The default setting is OFF. If Dlink Security enabled, users performing network-wide diagnostics must log in before being able to change the configuration of the radio via Dlink. Wireless Security Login Password Administrator PasswordWhen the transceiver is shipped from the factory, the password is normally set to the default entry of admin. It is recommended that it be changed at the time of installation to one that is known only to the Administrator or authorized user of the system. The password should be changed periodically to maintain the best security. Passwords are case sensitive and may use up to 13 alpha-numeric characters. Do not use punctuation mark characters. You will be required to enter the current password to set a new one. Follow the prompts, and refresh your web browser (typically View>>Refresh or View>>Reload at the top menu bar) to apply the change to all pages. TIP: For enhanced security, consider using misspelled words, a combi-
nation of letters and numbers, and a combination of upper and lower case letters. Also, the more characters used (up to 13), the more secure the password will be. These strategies help protect against sophisticated hackers who may use a database of common words (for example, dictionary attacks) to determine a password. 66 SD Series Technical Manual MDS 05-4846A01, Rev. G Encryption Phrase Encryption PhraseIf encryption has been enabled, a valid phrase must also be set. Both the sending and receiving station must have the same phrase for communication to occur. The phrase must have at least 8 characters (maximum of 37), and any printable character may be used. 6.4 Maintenance & Status Screen The Maintenance & Status screen (Figure 35) provides access to several tools used in testing the radio and performing routine management tasks. Individual screens may be selected beneath Maintenance & Status at the left side of the screen. Figure 35. Maintenance & Status Screen MDS 05-4846A01, Rev.

erally most meaningful from an AP perspective. The MAC Route screen shows all currently communicating radios in a network running in Packet w/MAC mode. Screen content varies with configuration. The following items are dis-
played on a fully populated screen for each radio, and appear in the blank area of the MAC Routes screen:
UnitUnit address of the radio. ESNExchange Sequence Number, an incrementing 8-bit sequence number used to uniquely identify packets coming from that radio. It is used for redundant packet filtering in case of re-transmissions. LinkCurrent link the radio is connected via, either DIRECT or through Store and Forward (SAF). Clear RoutesForces the radio to re-learn all actively communi-
cating radios in the network. Note that because the radio network is point-to-multipoint (from a Remote radio's perspective), the MAC Route function only contains infor-
mation about the Access Point. Radio Test The Radio Test functions are a collection of tools useful for testing the RF performance of the transceiver. It provides a way to key (activate) the transmitter, measure power output, run a spectrum test, and enable the built-in RTU simulator. 72 SD Series Technical Manual MDS 05-4846A01, Rev. G 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. Link Test RTU EnableSelect ON or OFF from the drop-down box. RTU NumberEnter the desired RTU number in this box. When you are done with these settings, press Commit Configuration to apply the changes. The primary use of the Link Test is to verify that a specific radio's set-
tings 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 respond to a Link Test message. Only the initiating radio requires con-
figuration when using the Link Test screen, and it is only available when operating in packet mode. A summary of data statistics is displayed on the right side of the screen, including transmit/receive packet counts, total bits, and total number of bit errors. NOTE: No other data traffic should be active when performing a Link-
test. Destination Unit AddressEnter the Unit Address of the other radio being tested. Linktest CountEnter the number of times for the message to be sent across the radio link. Response Timeouts (msec)Enter the time (in milliseconds) that will result in a timeout if no response is received within that period. Start TestSet this box to ON to start the Link Test, or OFF to stop the test. MDS 05-4846A01, Rev.

IntervalUse this box to specify how long (in seconds) between ping transmissions after a response is received. TimeoutUse this box to specify how long (in seconds) to wait for a ping response before a timeout occurs. RF Keying Test The RF Keying Test screen provides a way to place the transmitter on the air to check the measured RF power output, measure reflected power from an antenna system, or to provide a signal at a receiving station so that RSSI can be checked. Key RadioSet to ON to enable the RF keying test; OFF to disable it. The Commit Configuration button must be clicked to apply the setting. Measured RF PowerProvides an indication (in dBm) of the mea-
sured power output of the transmitter. 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. Spectrum Graph 74 SD Series Technical Manual MDS 05-4846A01, Rev. G To use the Spectrum Graph, you must first specify a center frequency and a span frequency. 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. Center FrequencyThe frequency (in MHz) that the graph will be centered on. Span FrequencyWidth (in kHz) of the spectrum to be examined. A sample spectrum graph from the transceiver is shown below. Alarm Test Example Spectrum Graph The Alarm Test screen provides a way to force an alarm for testing alarm reporting and radio response. When set to ON, clicking the Commit Configuration button sets an alarm, and the radios PWR LED begins to flash. An Alarm Test entry is also made in the Event Log, and the external alarm output status is changed. In redundant configurations such as SDxP/SDxDP/SDxDT packaged models, the Alarm Test can be used to force a switchover between redundant radios. The alarm test is a timed facility. When applied, it will assert for 30 seconds, and then deactivate. If active, it can be manually deactivated prior to timeout by setting the parameter to OFF, and clicking the Commit Configuration button again. MDS 05-4846A01, Rev.

It is best to begin troubleshooting at the master unit, as the rest of the system depends on the master for polling commands. If the master unit has problems, the overall operation of the network will be affected. It is good practice to start by checking the simple things. For proper operation, all radios in the network must meet these basic requirements:
Adequate and stable primary power Secure cable connections (power, data and Antenna) An efficient and properly aligned antenna system and a received signal strength of at least 90 dBm. (It is possible for a system to operate with weaker signals, but reliability may suffer.) The correct interface between the transceiver and the connected data equipment (correct cable wiring, proper data format, timing, etc.) Proper programming of the transceivers operating parameters. Table 14 provides suggestions for resolving system difficulties that may occur in the radio system. If problems persist, contact the factory for fur-
ther assistance. Refer to the inside back cover of this guide for contact information. Difficulty Unit is inoperative. Interference or signal overload is suspected. Table 14. Troubleshooting Guide Recommended System Checks a. Check for the proper supply voltage at the power connector. b. The transceivers internal fuse may have opened. Factory repair is required. a. Use the Spectrum Analyzer/Graph function to check for interference near the radio channel. b. Try re-orienting the station antenna to limit interference to and from other stations. c. For excessively strong signals, set RX Signal Attenuation to ON (Configuration>>Radio>>Advanced Settings). Note: Also affects the strength of desired, on-channel signals. MDS 05-4846A01, Rev.

Unit wont wake up from Sleep Mode Password lost or forgotten Alarm message RF Output Out of Range Transmitter keys when using terminal communications program. a. Check for secure interface connections at the radio and the connected device. b. Check the antenna, feedline and connectors. Reflected power should be less than 10% of the forward power reading
(SWR 2:1 or lower). c. If the Remote radio links, but performance is poor, check the received signal strength using the RSSI feature on the Radio Performance screen. If RSSI is low, it may indicate antenna problems, or misalignment of directional antenna headings. d. Verify proper programming of system parameters: mode, data interface baud rate, RF output power, etc. e. Check for alarms using the Statistics/Events screen. a. Verify correct IP address is set. b. Ensure PC is set to same subnet as radio. a. Excessive data throughput. Do not connect radio to a LAN with high traffic levels. b. Auto Power Save is shutting the port down. Disable Auto Power Save on Ethernet Port Configuration screen. a. Connect terminal emulator to COM1 port, cycle power, and press the Enter key within 10 seconds to obtain Login prompt. a. If in packet mode, check the packet settings screen for proper configuration. b. If in serial mode, check the COM1/COM2 port settings screen for proper configuration. a. Adjust packet mode settings. a. Disconnect the device connected to COM2, and disable Sleep Mode on the Device Settings Screen. b. Verify that the connected device is outputting the required 0 Vdc to 5 Vdc to control sleep mode on Pin 4 of COM2. Correct as necessary. c. Re-enable Sleep Mode on Device Settings Screen, re-connect device to COM2, and check for proper operation. Contact GE MDS for password reset authorization code. Proof of authorized user required. No load on Antenna connector or poor/shorted/open load. Check condition of antenna cable, connectors, and antenna system. Many terminal programs raise the RTS line by default. Keying can be avoided by setting the transceivers RTSkey parameter to OFF (Configuration>>Radio>>Advanced Settings) 7.1 LED Indicators The LED status indicators are an important troubleshooting aid, and should be checked whenever a problem is suspected. Table 10 on Page 31 describes the function of each status LED and their normal indi-
cations. 84 SD Series Technical Manual MDS 05-4846A01, Rev. G 7.2 Checking for Alarms/Events When an alarm condition exists, the transceiver registers it as an event. These events can be viewed the Device Managers Maintenance
& Status>>Alarm Summary>>All Alarms/Events screen. Here, you can check for currently active alarms, whether they be Major, Minor, Status Con-
ditions, or Informational Events. In addition, all historical events may be viewed by accessing the Device Managers Event Log screen. To access the Event Log, select Mainte-
nance & Status>>Event Log and click Show Log to view stored events (see Figure 36). Figure 36. Event Log Screen Both setting and clearing of major/minor alarms and status conditions are logged, as well as informational events (i.e., remote rebooted, repro-
gramming in process, etc.). Major Alarms vs. Minor Alarms Major Alarms report serious conditions that generally indicate a hard-
ware failure, or other abnormal condition that will prevent (or seriously hamper) further operation of the transceiver. Major alarms generally indicate the need for factory repair. Contact your factory representative for further assistance. Minor Alarms report conditions that, under most circumstances will not prevent transceiver operation. This includes out-of-tolerance conditions, baud rate mismatches, etc. The cause of these alarms should be investi-
gated and corrected to prevent system failure. Status and Informational Events Status events indicate current states or conditions that are not errors. They are used merely to indicate process functions (i.e., Reprogramming in Process). Informational (Inform) events pertain to those items which have occurred since bootup. They may or may not indicate an error, and they do not show current conditions, just an event that occurred at some point after boot-up (i.e., Event #32 Booting Up). MDS 05-4846A01, Rev. G SD Series Technical Manual 85 Event Code Definitions Table 15 contains a listing of event codes that may be reported by the transceiver. The codes shown are a subset of a larger pool of codes used for various GE MDS products. For this reason, the table does not show a sequential listing of all code numbers.

While many system arrangements and applications are possible, there are a few constraints that system planners should be aware of when designing a radio network. Table 16 lists these constraints and explains how to avoid difficulty in operation. Table 16. Operating Constraints Constraint Minimum firmware version requirement RSSI display in strong signal environments Detailed Information When operating in Packet w/MAC mode, do not downgrade the firmware revision below REV400. Downgrading firmware to a lower revision will cause erratic and unpredictable behavior, including causing the radio to become continuously keyed. The RSSI facility limits the maximum displayed signal strength to 60 dBm. MDS 05-4846A01, Rev. G SD Series Technical Manual 87 Table 16. Operating Constraints (Continued) Constraint Radio operation in strong signal environments DC input voltage (SD4) Detailed Information Operation with very strong receive signals (>-60db) may require selection of the programmable RX Signal Attenuation feature (see Advanced Settings screen). Some higher bandwidth modems (e.g., 65000) may require further external attenuation if operating at even stronger signal levels (> -35dbm). Note that this is rarely a practical concern; the most likely scenario is in bench testing. Typical field deployments have normal signal strengths well below this threshold. Early SD4 models supported 10.5 to 16 Vdc power, not 10 to 30 Vdc. Check the labeling above the power connector to confirm the operating range for your unit. 88 SD Series Technical Manual MDS 05-4846A01, Rev.

(polling that interrupts payload data transmission) can be performed. To perform diagnostics without interrupting payload data, connect the PC to a radio defined as the root radio. This is defined using the Device Manager on a connected PC. The following path takes you to the screen where all diagnostic settings are made:
Configuration>>Radio>>Diagnostic Settings To define a radio as the root unit, go to the Dlink Type box in the Diag-
nostics Settings screen, and select Root from the drop-down list. Setting Up Diagnostics The steps below outline the basic procedure of setting up diagnostics for a radio. A more detailed description of remote diagnostics can be found in the Network-Wide Diagnostics System Handbook (05-3467A01). 1. At the AP/master radio, set the Dlink Type to Root. 2. Set the Dlink Type for all other radios in the network to Node. 3. On the root radio, set Dlink TCP Access to Enabled on the Diagnostic Settings Screen. 4. Connect a PC running the management software to the root radio, or to one of the nodes, using the radios Ethernet port. (This PC may also be the computer used to collect payload data, as shown in Figure 37.) 5. Launch the diagnostic/NMS application at the PC. (Refer to the associated Users Guide for instructionsPulseNET: Part No. 05-4942A01; InSite: Part No. 05-3696A01. 8.2 Over-the-Air Firmware Upgrades A major feature of the radio is the ability to reprogram remotes in the network without the need to physically visit each radio site. This is accomplished using the over-the-air (OTA) channel. OTA reprogram-
ming always re-programs the Inactive firmware image of the radio to ensure that active firmware is not accidentally overwritten. 90 SD Series Technical Manual MDS 05-4846A01, Rev. G NOTE: OTA reprogramming over a narrowband radio channel can be a lengthy process, requiring up to several hours to complete. The time required depends on several factors, as discussed in the following section. Intrusive vs. Passive (Non-Intrusive) Mode Firmware code may be transmitted to stations in either intrusive or pas-
sive (non-intrusive) mode using the built-in diagnostic capabilities of the radio. When OTA reprogramming is initiated from either a root or node the firmware image is broadcast to all Remotes in intrusive or pas-
sive use of the channel. 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 programming radios over the air, but it comes at the cost of interruptions in the primary use of the radio network. See Table 17 for the approximate times needed for intrusive reprogram-
ming. Table 17. Approximate Reprogramming TimesIntrusive Mode Modem Speed
(bps) Approximate Time Required 1 hour, 30 minutes 35-40 minutes 20-25 minutes 4800 9600 19200 Radio assumptions: Signal strength -85 dBm or stronger, Packet Size: 40, Block Size: 512, Retry: 3 Polling assumptions: Serial polling with 1-second poll time, sending random data at 50-100 bytes. Slower polling times will significantly increase completion time. Polling should be temporarily suspended while OTA reprogramming is active. NOTE: Intrusive mode should be used only when the radio channel can be devoted to the reprogramming operation, as payload data will be interrupted. Passive (Non-intrusive) operation piggy-backs reprogramming data onto normal payload data streams, thus allowing payload data to con-
tinue uninterrupted. This mode requires payload data to be sent so that the reprogramming data can be carried. NOTE: Radio networks configured for Packet w/MAC operation support intrusive operation while still sending payload data. Data is sent at the first chance, and does not wait for user data to be sent. MDS 05-4846A01, Rev. G SD Series Technical Manual 91 The disadvantage to passive operation is that it takes longer to convey the reprogramming information since it is must be attached to existing data transactions. See Table 18 for the approximate times needed for passive reprogramming. Table 18. Approximate Reprogramming TimesPassive Mode Modem Speed
(bps) Approximate Time Required 6 hours, 7 minutes 1 hour, 30 minutes 1 hour, 30 minutes 4800 9600 19200 Radio assumptions: Signal strength -85 dBm or stronger, Packet Size: 40, Block Size: 512, Retry: 3 Polling assumptions: Serial polling with 1-second poll time, sending random data at 50-100 bytes. Slower polling times will significantly increase completion time. NOTE: It is possible for Remote radios receiving a firmware upgrade to complete reprogramming before the initiating station does. This is because transmissions are sent out broadcast style and will be sent up to the number of times entered in the Retry Count parameter of the radio. In a strong signal environment, the image may be received successfully the first time, but the initiator does not know this, and continues broadcasting image data blocks until the specified retry count has been reached. OTA Reprogramming Overview The 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. Once an OTA reprogram session has started, the initiating radio selects either the active or inactive image stored in its non-volatile storage which is copied to all the other radios in the network. The initiator 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 initiating station remains unaware of the number or success of downstream radios participating in reprogram-
ming. During reprogramming, the status of the reprogramming will be avail-
able on all the radios participating in the process. Because the initiator is broadcast-only this status can only indicate progress toward sending out of all of the messages. On the Nodes, the progress toward completion of reception of reprogramming information is indicated. 92 SD Series Technical Manual MDS 05-4846A01, Rev. G Receiving stations can automatically reboot to the new image after suc-
cessful reprogramming. Alternatively, there is an OTA reboot command that can be broadcast from the initiator to all receiving stations. This last option instructs the receivers to reboot to a specific firmware revision if available, and not already running at that revision. Cancelling OTA Reprogramming During the reprogramming operation the user has the ability to cancel reprogramming at anytime either on the initiator, which will affect all radios, or on individual receiving stations. Note that cancelling repro-
gramming at the initiator results in all radios in the network having only one (instead of two) applications programmed in their image banks. That is, the inactive image (which was only partially upgraded) will be corrupt and unusable until reprogrammed at a later time. Error Conditions/Recovery Other than cancelling the reprogramming process, there are few error conditions that the initiator knows or can do anything about. Receiving radios perform checks and verification on the incoming data. If after the end of the reprogramming sequence a radio still has an invalid image
(for whatever reason) the radio will not reboot but continue running with its active, and valid image. Execution and Screen Examples Displayed information during reprogramming (at Root radios):

Command line/scripting modeWhere text-based commands are used to manage the radio, typically by means of an automated scripting system, rather than by manual entry. (Refer to SD Serial/Telnet Management Supplement, Part No. 05-6193A01 for a summary of text commands.) Changing COM1 Modes The Device Manager may be used to change the COM1 operating mode by accessing the Configuration>>Communication Ports>>Com 1 Port Settings screen (see COM1 Port Settings on Page 62). Using this screen, the Startup Mode and Current Mode may be set to either Console or Data from the drop-down selections. 94 SD Series Technical Manual MDS 05-4846A01, Rev. G How Sleep Mode Works NOTE: The COM1 operating mode may also be set using a PC terminal connected directly to the port. See SD Serial/Telnet Management Supplement, Part No. 05-6193A01 for details. 8.4 Implementing Sleep Mode Sleep Mode places the transceiver into a low power hibernating state, with a nominal current draw of less than 10 mA (at 13 Vdc) and a wake-up time of approximately 50 milliseconds. Sleep Mode is often used at battery/solar-powered sites to conserve power. The ability to enter Sleep Mode is controlled through the Device Set-
tings Screen (see Device Settings on Page 43), but an active low on Pin 4 of the COM2 port is what actually places the radio in Sleep Mode. NOTE: Sleep mode is not intended for use on a master radio. When Sleep Mode is enabled via the Device Settings Screen, the state of Pin 4 on COM2 is continuously monitored to detect a request to enter sleep mode from an external device (RTU, PLC, etc.). For ease of use, there are certain conditions which temporarily override the sleep request to prevent unwanted behavior of the radio. These conditions are:
1. The radio must be powered up for at least 60 seconds before it is allowed to enter sleep mode. 2. Any user-originated activity on the console terminal disables entering sleep mode for 30 seconds, measured from the time of last keystroke. 3. When locally reprogramming the transceivers firmware, sleep mode is disabled throughout the reprogramming time, and is sup-
pressed for 30 seconds thereafter. 4. The passage of payload data does not inhibit sleep mode. Sleep Mode Example This section describes how to implement Sleep Mode in a typical sce-
nario. Before using Sleep Mode, the following conditions must be met to provide proper operation and avoid damage to the transceiver:
a. Sleep Mode must be enabled on the radios Device Settings Screen. b. Output voltage to the radio must not exceed +5.0 Vdc. c. Output voltage to wake up the radio must be between +2.0 Vdc and +5.0 Vdc. MDS 05-4846A01, Rev. G SD Series Technical Manual 95 d. Output voltage to enter Sleep Mode must be +0.6 Vdc or less. With the above conditions met, you are ready to use Sleep Mode. As a working example, suppose you need communication to each Remote site in your network only once per hour. Program the RTU/PLC at the Remote sites to raise an RS-232 line once each hour (DTR for example), and wait for a poll and response before lowering it again. Connect the RS-232 line to Pin 4 of the radios COM2 port. This allows each Remote to be polled once per hour with a significant savings in power consump-
tion. 8.5 User-Programmable I/O Functions The transceiver can be internally configured to provide three user I/O functions on the COM1 and COM2 data connectors. These signals are commonly used for RTU resetting or for input monitoring. Once the transceiver has been properly configured, these pins can be activated through compatible NMS software, such as PulseNET or InSite. The jumpering changes required to enable these functions are beyond the scope of this manual. Consult the factory for further information on enabling and using these I/O functions. 8.6 Technical Specifications GENERAL Frequency Range:

ABBREVIATIONS If you are new to digital radio systems, some of the terms used in this guide may be unfamiliar. The following glossary explains many of these terms and will prove helpful in understanding the operation of the trans-
ceiver. 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 mes-
saging because it is not dependent upon the RTU polling cycle. Antenna System GainA figure, normally expressed in dB, repre-
senting the power increase resulting from the use of a gain-type antenna. System losses (from the feedline and coaxial connectors, 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 communication channel. Bridging(see Ethernet Bridging) ByteA string of digital data usually made up of eight data bits and start, stop and parity bits. CkeyedPertains to continuously keyed master stations (full-duplex). CTSClear to Send Decibel (dB)A measure computed from the ratio between two signal levels. Frequently used to express the gain (or loss) of a system. Data Circuit-terminating EquipmentSee DCE. Data Communications EquipmentSee DCE. Data Terminal EquipmentSee DTE. dBiDecibels referenced to an ideal isotropic radiator in free space. Frequently used to express antenna gain. 100 SD Series Technical Manual MDS 05-4846A01, Rev. G dBmDecibels referenced to one milliwatt. An absolute unit used to measure signal power, as in transmitter power output, or received signal strength. DCEData Circuit-terminating Equipment (or Data Communications Equipment). In data communications terminology, this is the modem side of a computer-to-modem connection. The transceiver described in this manual is hardwired as a DCE device. Digital Signal ProcessingSee DSP. DLINKData Link Mode. This is a GE MDS-proprietary protocol used when the transceiver is in diagnostics mode. DSPDigital Signal Processing. The transceivers DSP is the core operating unit of the transceiver through which nearly all functions depend. DTEData Terminal Equipment. A device that provides data in the form of digital signals at its output. Connects to the DCE device. ETHEthernet Ethernet BridgingA mode of operation for the transceiver where the radio decides whether messages are handled locally or sent intact over-the-air. Fade MarginThe greatest tolerable reduction in average received signal strength expected under most conditions. Provides an allowance for reduced signal strength due to multipath fading, slight antenna movement or changing atmospheric losses. A fade margin of 20 to 30 dB is usually sufficient in most systems. FPGAField Programmable Gate Array FrameA segment of data that adheres to a specific data protocol and contains definite start and end points. It provides a method of synchro-
nizing transmissions. GateAn operating mode of the transceiver with respect to diag-
nostic/management activities. See also NODE, PEER, and ROOT. Hardware Flow ControlA transceiver feature used to prevent data buffer overruns when handling high-speed data from the RTU or PLC. When the buffer approaches overflow, the radio drops the clear-to-send
(CTS) line, which instructs the RTU or PLC to delay further transmis-
sion until CTS again returns to the high state. Host ComputerThe computer installed at the master unit, which con-
trols the collection of data from one or more remote sites. I/OInput/Output MDS 05-4846A01, Rev. G SD Series Technical Manual 101 IPInternet Protocol Intrusive DiagnosticsA mode of remote diagnostics that queries and commands radios in a network with an impact on the delivery of the system payload data. See Active messaging. LANLocal Area Network LEDLight Emitting Diode LatencyThe delay (usually expressed in milliseconds) between when data is applied to TXD (Pin 2) at one radio, until it appears at RXD
(Pin 3) at the other radio. Listen Before TransmitA collision avoidance mechanism that attempts to allow transmission only when the channel is clear. mAMilliamperes (current flow) MACMedia Access Control MASMultiple Address System. A radio system where a central master unit communicates with several remote stations for the purpose of gathering telemetry data. Master (Station)Radio which is connected to the host computer. It is the point at which polling enters the network. Multiple Address SystemSee MAS. Network-Wide DiagnosticsAn advanced method of controlling and interrogating GE MDS radios in a radio network. NodeAn operating mode of the transceiver with respect to diag-
nostic/management activities. See also GATE, PEER, and ROOT. Non-intrusive diagnosticsSee Passive messaging. OTAOver-the-Air PAPower Amplifier Packet RadioA transmission scheme in which data elements are assembled into units, that are consecutively numbered and error-checked at the time of transmittal. Errored packets result in retry requests from the receiving station. Passive messagingThis is a mode of diagnostic gathering or repro-
gramming that does not interrupt payload system polling communica-
tions. Diagnostic/reprogramming data is sent/collected non-intrusively over a period of time; polling messages are carried with payload system data (contrast with active messaging). 102 SD Series Technical Manual MDS 05-4846A01, Rev. G Payload dataThis is the applications communication data which is sent over the radio network. PeerAn operating mode of the transceiver with respect to diag-
nostic/management activities. See also GATE, NODE, and ROOT. Point-Multipoint SystemA radio communications network or system designed with a central control station that exchanges data with a number of remote locations equipped with terminal equipment. PollA request for data issued from the host computer (or master PLC) to a remote radio. PLCProgrammable Logic Controller. A dedicated microprocessor configured for a specific application with discrete inputs and outputs. It can serve as a host or as an RTU. PPMParts per Million Programmable Logic ControllerSee PLC. Remote (Station)A radio in a network that communicates with an associated master unit. Remote Terminal UnitSee RTU. Redundant OperationA station arrangement where two transceivers and two power supplies are available for operation, with automatic switch-over in case of a failure. RootAn operating mode of the transceiver with respect to diag-
nostic/management activities. See also GATE, NODE, and PEER. RTSRequest-to-send RTURemote Terminal Unit. A data collection device installed at a remote radio site. An internal RTU simulator is provided with the trans-
ceiver to isolate faults to either the external RTU or the radio. RXAbbreviation for Receive. See also TX. SAFStore and Forward. An available feature of the radio where data is stored by a designated Remote, and then retransmitted to a station beyond the communication range of the AP. Signal-to-Noise RatioSee SNR. SCADASupervisory Control And Data Acquisition. An overall term for the functions commonly provided through an MAS radio system. SNRSignal-to-Noise ratio. A measure of how well the signal is being received at a radio relative to noise on the channel. MDS 05-4846A01, Rev. G SD Series Technical Manual 103 SSIDSecure Silicon Identifier Standing Wave RatioSee SWR. Supervisory Control And Data AcquisitionSee SCADA. SWRStanding Wave Ratio. A parameter related to the ratio between forward transmitter power and the reflected power from the antenna system. As a general guideline, reflected power should not exceed 10%
of the forward power ( 2:1 SWR). TelnetA terminal emulation protocol that enables an Internet user to communicate with a remote device for management activities as if it were locally connected to a PC. Terminal ServerAn available feature on the radio which encapsu-
lates serial data from the COM1/COM2 ports, and sends it over the air as IP packets. The data is decapsulated at the receiving end and routed to the appropriate COM ports. Transparent ModeA mode in which payload data is unchanged from its original format when it is sent over the air. A radio in this mode is said to be transparent to connected equipment at each end of a link. TXAbbreviation for Transmit. See also RX.

For this reason, the equipment should be returned to the factory for any PC board repairs. The factory is best equipped to diagnose, repair and align your unit to its proper operating specifications. If return of the equipment is necessary, you will be issued a Service Request Order (SRO) number. The SRO number will help expedite the repair so that the equipment can be repaired and returned to you as quickly as possible. Please be sure to include the SRO number on the outside of the ship-
ping box, and on any correspondence relating to the repair. No equipment will be accepted for repair without an SRO number. A statement should accompany the unit describing, in detail, the trouble symptom(s), and a description of any associated equipment normally connected to it. It is also important to include the name and telephone number of a person in your organization who can be contacted if addi-
tional information is required. Note: A backup copy of the products programming code should be retained (if applicable), as units are normally returned from the factory in a default state. The unit must be properly packed for return to the factory. The original shipping container and packaging materials should be used whenever possible. All factory returns should be addressed to:
GE MDS, LLC Product Services Department
