E 2.0 PRODUCT DESCRIPTION The SD Transceiver is a software-configurable, industrial radio for use in licensed data acquisition networks. It can 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 can be made for both serial

(RS-232/RS-485) and local Ethernet protocols. The radios x710 Mode is designed primarily for use in serial MDS x710 radio networks where a central station communicates with each remote, one at a time, to convey data and control signals. For models operating in this mode, the radio offers direct, drop-in compatibility with existing, older x710 networks while providing additional functionality not found in MDS x710 radios. An SD Transceiver in x710 mode looks like an x710 with respect to over-the-air transmission and all serial user inter-

face commands (plus some new SD-specific commands). The transceiver employs digital signal processing (DSP) technology and a fully digital transmit and receive IF chain to provide robust communi-

cations even under adverse conditions. Digital signal processing also helps eliminate the effects of component variations or temperature swings, resulting in an optimized performance. 2.1 Front Panel Connectors and Indicators Figure 2 shows the transceivers front panel connectors and indicators.

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 ideal for use in systems containing a mix of newer SD radios and legacy MDS x710 units. This manual covers x710 Mode radios. Packet Mode (including Packet w/MAC)Payload data from the radios serial or Ethernet ports is assembled into packets and transmitted over the air. Packet mode supports Ethernet Bridging, AES 128-bit encryption, and multihost operation. This mode is ideal for networks containing all SD radios. This manual does not cover Packet Mode radios. See below for applicable manuals. Transparent ModeThis mode is over-the-air compatible with MDS x710 transceivers, while supporting payload data on the Ethernet interface. This mode is ideal for mixed networks con-

taining SD and MDS x710 radios. It allows currently deployed x710 networks to add the ability to support Ethernet data. This manual does not cover Transparent Mode radios. See below for applicable manuals. For Packet Mode and Transparent Mode operation, refer instead to the following manuals for instructions:

It consists of a central master station and several associated remote units as shown in Figure 4. An MAS network provides communication between a central host computer and remote terminal units (RTUs) or other data collection devices. The operation of the radio system is transparent to the computer equipment. Often, such a system is used to convey telemetry data to and from widely separated remote radios. Typical applications include automatic, remote monitoring of gas wells, water tank levels, electric power distri-

bution systems, and similar control and measurement functions. The radio system can replace a network of remote monitors currently linked to a central location using leased telephone lines or other hard-

wired means. At the central office of such a system, there is usually a dedicated computer and some means of switching between individual 6 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E lines coming from each remote monitor. In this type of system, there is a modulator/demodulator (modem) at the main computer and at each remote site, usually built into the remote monitor itself. Since the cost of leasing a dedicated-pair phone line is quite high, wireless technology is often used as a cost-effective alternative. RTU REMOTE RADIO Invisible place holder REMOTE RADIO RTU RTU REMOTE RADIO RTU REMOTE RADIO MASTER STATION OR: SDA-Augmented Master Station HOST SYSTEM Figure 4. Typical MAS Point-to-Multipoint Network Point-to-Point System Where permitted, the transceiver can also be used in a point-to-point arrangement. A point-to-point system consists of just two radiosone serving as a Master and the other as a Remote (see Figure 5). It provides a simplex or half-duplex communications link for the transfer of data between two locations. Invisible place holder Figure 5. Typical Point-to-Point Link MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 7 Continuously-Keyed versus Switched-Carrier Operation The keying behavior of the master station can be used to describe the operation of an MAS system. Continuously-Keyed operation means the master station transmitter is always keyed and an RF carrier is always present, even when there is no data to send. The master station is always transmitting and receiving simultaneously. Different frequencies must be used for transmit and receive. This is the method used in many MAS systems, as is shown in Figure 4. This network arrangement is useful for high-speed polling applications. NOTE: The SDx acting as a master does not support full-duplex oper-

ation. Switched-Carrier operation is a half-duplex mode of operation where the master station transmitter is keyed to send data and unkeyed to receive. Single-Frequency (Simplex) Operation Single-frequency operation (also known as simplex) is a special case of switched-carrier operation. Single frequency operation is automatically selected whenever the transmit and receive frequencies are set to the same value. NOTE: Data turn-around times are increased when inter-working with an MDS x710 network. This restriction does not apply to homogeneous SD networks. 4.0 INSTALLATION PLANNING Careful planning of the installation site helps achieve optimal performance from the transceiver. This section discusses pre-installation factors. After reviewing this section, refer to the step-by-step installation procedures begin-

ning on Page 18. 4.1 Typical Installation Figure 6 shows a typical station arrangement. Wiring connections and installa-

tion steps for the transceiver are provided in the sections that follow. 8 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E Figure 6. Typical Remote Station Arrangement 4.2 Mounting Options The transceiver is normally provided with flat mounting brackets attached to the bottom of the radio as shown in Figure 7. An optional 35 mm DIN rail mounting bracket is also available. See Optional DIN Rail Mounting on page 10. Invisible place holder

E SD Series Reference Manual (x710 Mode) 9 NOTE: To prevent moisture from entering the radio, do not mount the case with the cable connectors pointing up. Also, dress all cables to prevent moisture from running along the cables and into the radio. Transceiver dimensions are shown in Figure 8. Figure 8. SD Transceiver Dimensions Optional DIN Rail Mounting The unit can 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 9. The entire assembly then attaches to the mounting rail. Release Tab 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 9.

E 4.3 Antennas and Feedlines Antennas The transceiver can be used with a number of antennas. The exact style depends on the physical size and layout of your radio system. A direc-

tional Yagi (Figure 10) or corner reflector antenna is generally recom-

mended 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 10. 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 might reduce the range and reliability of the radio system. Table 2, Table 3, and Table 4 show the approximate losses that will occur when using various lengths and types of coaxial cable in the 200, 400, and 900 MHz bands. Regardless of the type used, the cable should be kept as short as possible to minimize signal loss. Table 2. Signal Loss in Coaxial Cables (at 200 MHz) Cable Type 10 Feet

The supply must be capable of providing at least 2.5 A of con-

tinuous current. NOTE: 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. A power connector with screw terminals is provided with each unit (see Figure 11). Strip the wire leads to 6 mm (1/4 inch) and insert in the wire ports. Be sure to observe proper polarity as shown in Figure 11. Figure 11. DC Power Connector (P/N 73-1194A39) NOTE: The radio is designed for use in negative ground systems only. 12 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E 4.5 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. 4.6 COM1 (Management) Connections The radios COM1 port is used to connect a PC for management or diag-

nostic purposes. Typically, a straight-through DB-9 cable can be used for this purpose. If desired, construct a cable as shown in Figure 13, con-

necting Pins 2 (RXD), 3 (TXD), and 5 (GND). Other custom cables or adapter kits are only needed for analog operation or other special-use applications. 5 1 9 6 Figure 12.

E 4.7 COM2 (Data) Connections The COM2 port (Figure 14) is used to connect the radio to an external DTE telemetry device supporting the EIA/RS-232 or EIA/RS-485 (bal-

anced) format, depending on how the radio is configured. Typically, a straight-through DB-9 cable is used to connect to COM2. The radio sup-

ports data rates of 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps (asynchronous data only). The following data formats are supported:

E SD Series Reference Manual (x710 Mode) 17 5.0 STEP-BY-STEP INSTALLATION In most cases, the steps given here are sufficient to install the trans-

ceiver. Refer to INSTALLATION PLANNING on Page 8 for addi-

tional details. 1. Mount the transceiver. Attach the mounting brackets to the bottom of the transceiver case (if not already attached), using the four 6-32 x 1/4 inch (6 mm) screws supplied. Mounting bracket dimensions are shown in Figure 7 on page 9. 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 13.) 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. Use low-loss coaxial feedline, and keep the feedline as short as possible. 3. Connect the data equipment. Make the connection using Serial protocols (RS-232/RS-485). Connect a serial device to COM2 on the front panel. The radio is hardwired as a DCE device. Use a straight-through cable for most applications. 4. Connect primary power. Input power must be within the range printed above the power connector, and capable of providing at least 2.5 A. A power connector with screw-terminals is provided with the unit (see Figure 11 on page 12). 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. 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. NOTE: To comply with IEC61850-3, paragraph 5.7.1.2, surge suppression must be used across the power supply for Class 3 and 4 severity levels as defined by IEC 61000-4-5 Annex A. 18 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E 5.1 Initial Startup & Checkout In-service operation of the transceiver is completely automatic. Once the unit has been properly installed and configured, 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. 2. Observe the LED status panel for proper indications (Table 10). 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 RSSI command can be used to display signal strength. Turn the antenna heading slowly so that the RSSI display can be updated. NOTE: The RSSI function limits the maximum displayed signal strength to 60 dBm. Invisible place holder Table 10. LED Status Indicators

There are numerous settings that go beyond basic configuration, and you may wish to access these later. A full description of commands is provided in TRANSCEIVER MANAGEMENT on Page 21. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 19 Serial vs. Telnet Access, and the Device Manager There are three methods available to communicate with the transceiver for configuration and management purposes: Serial (COM1 DB9 con-

nector), Telnet (ETHERNET RJ-45 connector), and the web-based Device Manager. Both serial and telnet present identical screens, but the method of access is different for each. The Device Manager provides a web interface using the transceivers built-in web server, and is the newest configuration interface, although all three options accomplish the same results. NOTE: Firmware reprogramming is best handled using the Device Manager. The focus of this section is on Serial access, but Telnet may also be used by following these additional points, which replace Steps 1-3 below:

Connect to the radio with a PC that is on the same IP network as the transceiver. Launch a Telnet program, and connect to the radio using its programmed IP address. The default IP address for an SD is 192.168.1.1. If you do not know the IP address of the radio, follow the serial configuration instructions below, where you can determine the radios address and continue configuration of the radio, or ask your network administrator. Connecting a PC & Setting Basic Parameters Follow these steps to configure the transceiver for its first use:

1. Connect a PC to the radios COM1 serial port as shown in Figure 17.

(Maximum recommended cable length: 50 ft./15 m) NOTE: Not all PCs include a serial port. If one is not available, a USB port may be used, along with a USB-to-Serial adapter (with appropriate driver software). Adapters are available from many manufacturers. NOTE: If COM1 has been configured to boot into data mode, pressing within 10 seconds of boot-up switches it into console ENTER

(management) mode. Console mode is required for the following steps. 2. Launch a terminal communications program, such as HyperTer-

minal (included with many Windows-based PCs) with the fol-

lowing communication parameters: 8 bits, no parity, one stop bit

(8N1), flow control disabled, VT100 emulation. The radios COM1 port automatically determines the connected baud rate (within the range of 1200115200 bps). The preferred baud rate is 9600 bps. 20 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E 3. Press the ENTER key several times at half-second intervals to choose and select the correct baud rate. This will result in the >

prompt. Invisible place holder Transceiver PC Running Terminal Session DB-9M to COM1 Port Figure 17. PC Connection to Transceiver NOTE: TX and RX frequencies might not be set when the radio is shipped from the factory, depending on ordering options. If frequencies have not been set, the PWR LED will flash, indi-

cating an alarm condition. The alarm will clear after the frequencies are set. In all cases, users should verify that the frequencies are properly set in accordance with the station license. 6.0 TRANSCEIVER MANAGEMENT To perform transceiver management, connect a PC as described in Section 5.1, Initial Startup & Checkout and obtain the > prompt. 6.1 Software Commands Table 11 is a reference chart of software commands for the transceiver.

This section provides detailed information for the user commands previously listed in Table 11 (Page 21). 24 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E In many cases, the commands shown here can be used in two ways:

Type only the command name to view the currently programmed data. Set or change the existing data by typing the command, followed by a space, and then the desired entry. In the list below, allowable programming variables, if any, are shown in brackets following the command name. Authorization Key AK The transceivers feature set may be expanded (if all features are not currently enabled) by entering a new authorization key, which can be purchased from GE MDS. Contact the factory to obtain a new Authori-

zation Key. ALARM Alarm Summary The ALARM command displays a summary of the radios current oper-

ating condition. An eight-digit code is presented which can be decoded as described in Major Alarms vs. Minor Alarms on Page 41. AMASK [0000 0000FFFF FFFF]

Alarm Mask The AMASK command displays or sets which events cause an alarm output signal to be active. Normally, the mask is FFFF FFFF, meaning that any of the 32 possible events will activate the alarm output signal. Entering the AMASK command alone displays the current setting of alarm events in hexadecimal format. Entering the AMASK command followed by an eight-digit hexadecimal number reprograms the specified events to trigger an alarm. The eight-digit hexadecimal number used as the command parameter specifies 0 to 32 events that can trigger the external alarm output. (See Table 14 on Page 41 for a list of events.) The hex value for the mask cor-

responds to the hex value for the STAT command (Page 38). Each bit that is a 1 identifies an alarm condition that can trigger the external output. For more information on configuring the alarm response, contact GE MDS. ASENSE [HI, LO]

Alarm Sense The ASENSE command sets or displays the sense of the alarm output at Pin 6 of the COM2 port. Entering the ASENSE command alone shows whether the alarm output is active high or low. Entering the ASENSE command followed by HI or LO resets the alarm output to active high or low. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 25 AUDIO [ON, OFF]

Audio Monitor/

Orderwire Status Used to set or display Audio Monitor/Orderwire functionality (on or off). If AUDIO ON is selected, the radios transmit functionality will switch to analog whenever PTT is asserted. BAUD [xxxxx abc]

Data Interface Port Baud Rate This command sets (or displays) the communication attributes for the DATA INTERFACE port (COM2). It has no effect on the COM1 manage-

ment port. The first parameter (xxxxx) is baud rate. Baud rate is specified in bits-per-second (bps) and must be one of the following speeds: 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200 bps. The second parameter of the BAUD command (abc) is a three-character block indicating how the data is encoded:

a = Data bits (7 or 8) b = Parity (N for None, O for Odd, E for Even) c = Stop bits (1 or 2) The factory default setting is 9600 baud, 8 data bits, no parity, 1 stop bit

(Example: 9600 8N1). BIN [DATA, CLEAR]

Data Counters Used to display or clear the data counters. Use BIN DATA to display. Use BIN CLEAR to clear the counters. BOOT Software Reboot Used to initiate a software reboot. Use BOOT alone to reboot the cur-

rently running firmware image. Use BOOT 1, BOOT 2, or BOOT OTHER to reboot to a specific firmware image. RX Data Buffer BUFF [ON, OFF]

This command sets or displays the received data handling mode of the radio. The command parameter is either ON or OFF. The default is ON. The setting of this parameter affects the timing of how received RF data is sent from the DATA INTERFACE connector. Outgoing (transmitted) data is not affected by this setting. If data buffering is OFF, the radio operates with the lowest possible average latency. Data bytes are sent from the DATA INTERFACE port as soon as an incoming RF data frame is disassembled. Average and typ-

ical latency will be minimized, but idle character gaps may be intro-

duced into the outgoing data flow. 26 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E If data buffering is ON, the radio operates in seamless mode. Data bytes are sent over the air as quickly as possible, but the receiver buffers

(stores) the data until enough bytes have arrived to cover worst-case gaps in transmission. This mode of operation is required for protocols such as MODBUS that do not allow gaps in their data transmission. NOTE: Seamless mode (BUFF ON) is intended only for applications where the transmitters baud rate is greater than or equal to the receivers baud rate. Enforcement of this rule is the users responsibility. CKEY [ONOFF]

Key TX Continuously The CKEY command enables or disables the continuously-keyed func-

tion of the radio. When CKEY is set to ON, the radio is continuously keyed and the Timeout Timer is disabled. CTS [0255]

Clear-to-Send Time The CTS (clear-to-send) command selects or displays the timer value associated with the CTS line response. The command parameter ranges from 0 to 255 milliseconds. For DCE operation, the timer specifies how long to wait after the RTS line goes high, before the radio asserts CTS and the DTE can transmit the data. A CTS value of zero keys the radio and asserts the CTS line immediately after the RTS line goes high. For CTS Key operation (see DEVICE command), the timer specifies how long to wait after asserting the CTS, before sending data from the DATA INTERFACE port. A timer value of zero means that data will be sent from the data port without imposing a key-up delay. (Other delays might be present based on selected radio operating parameters.) CTSHOLD [060000]

Used in DEVICE CTS KEY mode, this command sets the amount of time in milliseconds that CTS remains present after transmission of the last character from the RXD pin of the DATA port. This hold time can be used to prevent squelch tail data corruption when communicating with other radios. The CTSHOLD setting can range from 0 to 60000 ms (60 seconds). The default value is 0, which means that CTS will drop immediately after the last character is transmitted. If the command is entered when the radio is in DEVICE DCE mode, the response CTSHOLD N/A is shown. Clear-to-Send Hold Time MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 27 DATAKEY [ON, OFF]

Key on Data Activity The DATAKEY command enables or disables the ability of the radio to key the transmitter as data is received at the DATA INTERFACE connector. Asserting RTS keys the radio regardless of this command setting. If DATAKEY is set to ON, the radio will key when a full data-character is received at the transceivers DATA INTERFACE connector. If DATAKEY is set to OFF, the radio needs to be keyed by asserting RTS. DEV Modem Deviation Displays modem control deviation in Hertz (Hz). This is a read-only command, and cannot be changed in the field. DEVICE [DCE, CTS KEY]

Data Device Mode The DEVICE command controls or displays the device behavior of the radio. The command parameter is either DCE or CTS KEY. In DCE mode (the default setting), CTS will go high following RTS, sub-

ject to the CTS programmable delay time. If the DATAKEY command is set to ON, keying can be stimulated by the input of characters at the data port. Hardware flow control is implemented by signaling the CTS line if data arrives faster than it can be buffered and transmitted. In CTS KEY mode, the SD is assumed to be controlling another radio. The SD will still key based on the RTS line, but the CTS line is used as a key-

line control for the other radio. CTS is asserted immediately following the receipt of RF data, but data will not be sent out the DATA INTERFACE port until after the CTS programmable delay time has expired. (This gives the other radio time to key.) DKEY Unkey Transmitter This command deactivates the transmitter after it has been keyed with the KEY command. DLINK [ON/OFF/xxxx]

Diagnostic Link Use this command to configure the local diagnostic link protocol used in network-wide diagnostics. Entering DLINK ON enables the diagnostic link. Entering DLINK OFF dis-

ables the diagnostic link. To change the diagnostic link, enter DLINK followed by one of the fol-

lowing baud rates: 1200, 2400, 4800, 9600, 19200 (default), 38400, 57600, 115200. 28 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E NOTE: The radio is configured by default to be in DLINK mode. The COM1 port automatically determines the connected baud rate

(within the range of 1200115200 bps). Enter a series of Return Key presses about a half second apart until the > prompt appears. This indicates that the radio is ready to receive commands. DTYPE [NODE/ROOT]

Units Diagnostics Type This command establishes the local radio as a root radio or node radio for network-wide diagnostics. Entering DTYPE NODE configures the radio as a node radio. Entering DTYPE ROOT configures the radio as a root radio. Entering the DTYPE command alone displays the current setting. DUMP Read Current Unit Profile Modem TX Audio Pre-Emphasis This command causes all of the programmed settings to be displayed. EMP [ON/OFF]

This command displays or sets the TX pre-emphasis and RX De-Emphasis when the radio is operating with the analog mode and the radios MODEM is turned off (MODEM NONE). It should be set to match the other radios in the system. The use of pre- and de-emphasis can help reduce the detrimental influence of high frequency audio noise. ETHADDR Ethernet Address Displays programmed Ethernet MAC address (set at the factory). FORCEALARM [ON or OFF]

Force Alarm Generates a test alarm for 10 sec. Use to test alarm outputs and switch-over in redundant systems. FORCEDCD [ON or OFF]

Force DCD Forces Data Carrier Detect (DCD) to always be asserted. Use when con-

necting to equipment that requires a constant DCD indication. HELP User Help Show available commands. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 29 INIT Initialize EEPROM Defaults The INIT command is used to re-initialize the radios operating parame-

ters to the factory defaults. This can be helpful when trying to resolve configuration problems that might have resulted from the entry of one or more improper command settings. If you are unsure of which com-

mand setting caused the problem, this command allows you to get back to a known working state. The following changes to the radio are made when INIT is entered:

CTS is set to 0 DATAKEY is set to ON DEVICE is set to DCE PTT is set to 0 SCD is set to 0 TOT is set to 30 seconds and set to ON PWR is set to +37 dBm (5 watts) All other commands remain as previously set. INIT [SDx]

(Where x denotes SD radio model) Initialization (for standalone radio) This command sets the transceiver for normal operation outside the P-20 chassis by setting the following parameters to the values shown below:

ASENSE ACTIVE HI AMASK FFFF FFFF (assert alarm output on all alarms) RXTOT NONE (receive time-out timer disabled) Use this command to restore these three parameters to the standard transceiver defaults if it was previously used in a P-20 package. INIT [P-20]

Initialization for P-20 Implementation This command sets the transceiver for service inside a P-20 redundant chassis by setting the following parameters to the values shown below:

E IPCONFIG Ethernet Configuration Ethernet interface configuration. This command is used to display or change the configuration of the Ethernet interface. The command can be used in several ways:

IPCONFIG alone displays all current network settings. IPCONFIG DHCP [ON/OFF] is used to switch between DHCP and static addressing. IPCONFIG IP [ipaddr] is used to set a static IP address. IPCONFIG NET [netmask] and IPCONFIG GW [Gateway] are used to set subnet mask and gateway, respectively. KEY TX Key This command activates the transmitter. See also the DKEY command. MENU Menu Activate Activates the menu-based program within the transceiver (when sup-

ported), used for reprogramming the units firmware. MODEL1 Displays the factory software configuration of the radio. MODEL2 Displays the hardware configuration bill of material identifier. Model Number Information See Table 11 on Page 21 for information on these pre-programmed fields. MODEM [xxxx]

Analog/Digital Modem Selection This command selects the radios modem characteristics. For digital operation enter MODEM xxxx, where xxxx equals the modem selection of the radio. Table 12 shows the supported modem types. NOTE:For compatibility with an existing MDS x710 system, make sure to select the matching MODEM type. See Table 11. Table 12.

COM2 Settings Set or show COM2 data port interface settings. Push-to-Talk Delay PTT [0255]

This command sets or shows the key-up delay in milliseconds. This timer specifies how long to wait after the radio receives a key signal, before actually keying the radio. Push-to-Talk Configuration PTTSIG [OFF, LOW, HI]

Used to set or show the configuration of the push-to-talk signal. This signal is used for analog operation. TX RF Power Output Level PWR [2037]

NOTE: This function might be restricted due to regulatory constraints. This command displays or sets the desired RF forward output power set-

ting of the radio. The PWR command parameter is specified in dBm and can range from 20 through 37. The default setting is 37 dBm (5 watts). To read the actual (measured) power output of the radio, use the SHOW PWR command. A dBm-to-watts conversion chart is provided in Section 8.6 (Page 55). RESTORECONFIG Restore Configuration This command restores a user configuration. Command is timed and aborts in 3 sec if no response is provided. RESTOREDEFAULTS Restore Defaults This command restores the original factory configuration. Command is timed and aborts in 3 sec if no response is provided. Radio Mode RMODE [X710, TRANSPARENT, PACKET, CMAC, HELP]

Allows the reconfiguration of the SD operating mode. An MS radio model normally ships with x710 mode and provides the command inter-

face documented in this manual. Changing to a mode other than x710 causes the radio to exit the x710 command emulation interface and prompt for a user login. RSSI Received Signal Strength Indicator This command continuously displays the radios Received Signal Strength Indication (RSSI) in dBm, until you press the Enter key. Incoming signal strengths up to -60 dBm can be read. 34 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E NOTE: The RSSI samples the incoming signal for one to two seconds before providing an average reading to the connected PC. RTSKEY [ON, OFF]

RTS Keying Behavior Used to set/display how the radio responds to RTS keying. The default setting is RTSKEY OFF. RTSKEY ON causes the radio to respond to RTS by keying the transmitter. When RTSKEY OFF is selected, key-on-RTS is suppressed. RTU Emulator NOTE: Terminal emulators such as HyperTerminal and Procomm typically initiate the RTS signal continuously upon the start of a connection. When connected to the radios COM2 payload port, this typically causes the transmitter to remain constantly keyed. In such cases, RTSKEY OFF allows a terminal emulator to be connected to the radios COM2 port without the need for special cables or a break-out box. RTU [ON/OFF/0-80]

This command enables or disables the radios internal RTU simulator, which runs with proprietary polling programs such as poll.exe and rsim.exe. The internal RTU simulator is available whenever a radio has diagnostics enabled. This command also sets the RTU address that the radio will respond to. The internal RTU can be used for testing system payload data or pseudo bit error rate testing. It can be helpful in isolating a problem to either the external RTU or the radio. RX [xxx.xxxx]

Receive Frequency This command selects or shows the radios receive frequency in MHz. The frequency step size is 125 Hz. If the customer frequency has not been programmed at the factory, a default frequency will be programmed in the radio near the center of the frequency band. For a list of frequency bands per radio model, refer to Technical Specifications on Page 43. RXATTN [ON or OFF]

Receive Attenuation Enables or disables receive attenuation. Enable receive attenuation when a remote is in close proximity to a master (such as on a test bench). RXLEVEL [20 to 0]

RX Audio Output Level The RXLEVEL command selects or shows the desired receive audio output level. For more information, refer to the detailed description of analog operation beginning on Page 46. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 35 RX Tolerance RXTOL [NORMAL or CUSTOM]

The RXTOL command allows custom configuration of the receive toler-

ance, to improve performance with legacy radios (x790, x310, and so on). RXTOT [NONE, 1-1440]

Loss of RX Data Alarm Time The RXTOT command selects or shows the receive time-out timer value in minutes. This timer triggers an alarm (event 12) if data is not detected within the specified time. Entering the RXTOT command without a parameter shows the timer value in minutes. Entering the RXTOT command with a parameter ranging from 0 to 1440 resets the timer in minutes. (1440 minutes equals 24 hours.) Entering the RXTOT command with the parameter NONE disables the timer. SAVECONFIG Save Configuration Saves a user configuration. Command is timed and aborts in 3 sec if no response is provided. SCD [0-255]

Soft-Carrier Dekey This command shows or changes the soft-carrier dekey delay in milli-

seconds. This timer specifies how long to wait after the removal of the keying signal before actually releasing the transmitter. A value of 0 millisec-

onds will unkey the transmitter immediately after the removal of the keying signal. SER Radio Serial Number This command shows the radios serial number as recorded at the fac-

tory (non-configurable). SHOW [DC, PWR]

Show Power Settings The SHOW command shows different types of information based on the command variables. The different parameters are:

DCDisplay DC input/output voltages PWRDisplay RF power output SNR RX Signal-to-Noise Ratio This command continuously shows the signal-to-noise ratio of the received signal expressed in dB, until you press the Enter key. As used in this guide, the signal-to-noise measurement is based upon the signal level following equalization, for received frames. 36 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E The SNR is an indication of the received signal quality. A value of 10 dB represents a very poor signal. A value of 24 dB represents a very good signal. When the SNR command is used, it causes the DIAG. port to enter an update mode, and the signal-to-noise ratio is updated and redisplayed every 2 seconds. The SNR continuously updates until the pressed. ENTER key is SPECTRUM [xxx.xx]

Internal Spectrum Analyzer Activates the built-in spectrum analyzer tool (see Figure 18) that can be shown on a connected PC. This tool is helpful in diagnosing interference problems on or near your channel frequency. Access the spectrum analyzer by entering spectrum at the command prompt. A display appears showing detected signals on your current channel. Optionally, you can specify a frequency at the command prompt to view the surrounding spectrum of that frequency. To do this, enter spectrum xxx.xx, where xxx.xx is the frequency in MHz. A typical spectrum analyzer display is shown in Figure 18. The display creates a received signal strength indication (RSSI) vs. frequency plot for the fre-

quency and surrounding signals. By analyzing the display, you can determine the presence of other signals near the transceivers operating frequency. This information can be helpful in troubleshooting interference problems. Invisible place holder Figure 18. Internal Spectrum Analyzer Display SQUELCH [AUTO, BYPASSED]

ware. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 37 STAT Alarm Status This command shows the current alarm status of the transceiver. Switched Carrier If no alarms exist, the message NO ALARMS PRESENT appears. If an alarm does exist, a two-digit code (0031) is displayed and the alarm is identified as Major or Minor. A brief description of the alarm code is also given. If more than one alarm exists, the word MORE appears at the bottom of the screen, and additional alarms are viewed by pressing the key. Detailed descriptions of event codes are provided in Table 14 on Page 41. ENTER SWC [ON, OFF]

How you configure this command is based on whether or not the trans-

ceiver is listening to a continuously keyed master. If the master is not continuously keyed, then the master is operating in switched carrier mode and the transceivers SWC setting should be ON. If the master is continuously keyed, the transceivers SWC setting should be OFF. For B modem operation only. SWC should be OFF for A modems. NOTE: SWC must be set to ON for switched carrier operation. TFTP TFTP Settings Used to set/show all TFTP settings for upgrading the radios firmware through the Ethernet port using TFTP transfer. The command can be used in several different ways:

TFTP HOST [ipaddr] sets the IP address of the TFTP server hosting the firmware. TFTP FILE [filename] specifies the filename of the firmware to downloaded. TFTP GET is used after the above commands to begin the TFTP transfer. TFTP STATUS can be used to check on the progress of the down-

load. TEMP Internal Temperature This command shows the internal temperature of the transceiver in degrees Celsius. 38 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E TX Timeout-Timer TOT [1-255, ON, OFF]

This command sets or shows the transmitter Time-out Timer value

(1255 seconds), as well as the timer status (ON or OFF). If the timer is on, and the radio remains keyed for a longer duration than the TOT value, the transmitter is automatically unkeyed. When this happens, the radio must be commanded back to an unkeyed state before a new keying command is accepted. The default timer value is 30 seconds. TX [xxx.xxxx]

TX Frequency This command selects or shows the radios transmit frequency in MHz. The frequency step size is 125 Hz. If the customer frequency has not been programmed at the factory, a default frequency will be programmed in the radio near the center of the frequency band. TXLEVEL [20 to 0, AUTO]

TX Audio Input Level The TXLEVEL command selects or shows the expected transmit audio input level from an external modem. For more information, refer to the detailed description of analog operation beginning on Page 46. Unit Address For optimum performance, set this parameter to match the external modem level. For example TXLEVEL 10. TXLEVEL AUTO is also available

(default setting: 10 dBm). UNIT [10000...65000]

The unit address is the radios unique identity for the networks diag-

nostic activities. The unit responds to a request for a diagnostics code broadcast by the Master Station to all Remotes in an MAS network, if its unit address matches the number broadcast. The default number is programmed by the factory to the last four digits of the radios serial number. UPTIME Up Time Displays time since last system reboot. VERSION Firmware Version Displays package version information for each firmware image. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 39 7.0 TROUBLESHOOTING Successful troubleshooting of the radio system is not difficult, but it requires a logical approach. It is best to begin troubleshooting at the master station, as the rest of the system depends on the master for polling commands. If the master station has problems, the operation of the entire network might be compromised. 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. The radio contains an inter-

nal self-resetting fuse (5 A). Remove primary power to reset. Secure cable connections (RF, data and power). An efficient and properly aligned antenna system with a received signal strength of at least 90 dBm (it is possible for a system to operate with weaker signals, but reliability might be degraded). Proper programming of the transceivers operating parameters

(see Section 6.0, TRANSCEIVER MANAGEMENT on Page 21), especially the TX/RX frequency and MODEM type selec-

tions. The correct interface between the transceiver and the connected data equipment (correct cable wiring, proper data format, timing, etc.) 7.1 LED Indicators The LED status indicators are an important troubleshooting tool and should be checked whenever a problem is suspected. Table 10 on Page 19 describes the function of each status LED. 7.2 Event Codes When an alarm condition exists, the transceiver creates a code that can be read on a connected PC. These codes can be very helpful in resolving many system difficulties. Refer to Table 14 (Page 41) for a definition of the event codes. Checking for AlarmsSTAT command To check for alarms, enter STAT on the PC. If no alarms exist, the mes-

sage NO ALARMS PRESENT appears. If an alarm does exist, a two-digit alarm code (0131) is shown and the event is identified as a Major or Minor Alarm. A brief description of the alarm is also given. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 40 Major Alarms vs. Minor Alarms Major Alarms (1-16)report serious conditions that generally indicate a hardware 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 Technical Service representative for further assistance. Minor Alarms (17-32)report conditions that, under most circum-

stances, will not prevent transceiver operation. This includes out-of-tol-

erance conditions, baud rate mismatches, etc. The cause of these alarms should be investigated and corrected to prevent system failure. Event Code Definitions Table 14 contains a listing of event codes that can 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. Only the codes applicable to this product are shown, and this list is subject to change with product revi-

(TO SCADA APPLICATION) HOST COMPUTER Figure 19. Network-Wide Remote Diagnostics Setup If a PC is connected to any radio in the network, intrusive polling

(polling which briefly interrupts payload data transmission) can be per-

formed. To perform diagnostics without interrupting payload data trans-

mission, connect the PC to a radio defined as the root radio. A radio is defined as a root radio using the DTYPE ROOT command locally, at the radio. A complete explanation of remote diagnostics can be found in the Net-

work-Wide Diagnostics System Handbook (Part No. 05-3467A01). See the Handbook for more information about the basic diagnostic proce-

dures outlined below. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 45 1. Program one radio in the network as the root radio by entering the DTYPE ROOT command at the radio. 2. At the root radio, use the DLINK ON and DLINK [baud rate] commands to configure the diagnostic link protocol on the Management Port. 3. Program all other radios in the network as nodes by entering the DTYPE NODE command at each radio. 4. Use the DLINK ON and DLINK [baud rate] commands to configure the diagnostic link protocol on the Management Port of each node radio. 5. Connect same-site radios using a null-modem cable at the radios diagnostic ports. 6. Connect a PC running the management software to the root radio, or to one of the nodes, using the radios COM1 port. This PC can also be the PC used to collect payload data, as shown in Figure 19. 7. Launch the diagnostic program at the PC. 8.3 User-Programmable I/O Functions - Pending 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 analog input monitoring. Once the transceiver has been properly configured, these pins can be activated through compatible NMS software, such as Element Manager 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. 8.4 Analog Operation of the Transceiver The transceiver is designed for full digital modulation, while offering analog support to those systems that require it. Operation is compatible with the MDS x710 family of products, but some SD radio-specific command configuration and wiring might be necessary based on differ-

ences in SD hardware. This section provides important information for using the radio in analog service. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 46 Physical Interface The physical interface for analog operation utilizes pins on the radios COM1 (management) connector. This connector is multiplexed with the serial data lines used for software commands. The applicable pins of the DB-9 are as follows:

Pin 4Transmit Audio

(-20 dBm to 0 dBm, as set by TXLEVEL command) Pin 5Ground (negative supply potential) Pin 6Push-to-Talk (3 V TTL, 5 V tolerant) Pin 8Receive Audio

(-20 dBm to 0 dBm, as set by RXLEVEL command) Operational Characteristics Analog operation is available in two general modes: Analog-only or Mixed Analog/Digital. Analog-only operation is typically useful when interfacing with external analog modems. Operation is selected by specifying MODEM NONE. In this mode, RX and TX Audio are both always active; Carrier Detect output and the LINK LED are asserted based on the receiver unsquelching. Key sources automatically assume the use of TX Audio as the input source. In analog-only mode, carrier detect is based on squelch status. Mixed analog/digital operation is useful for orderwire application, or for analog systems that need to make use of GE MDS Network-Wide Diag-

nostics. Operation is enabled by selecting a digital modem type (for example, MODEM 9600) and selecting AUDIO ON. In this mode RX Audio is always active, but TX Audio only becomes active when the Push-to-Talk (PTT, Pin 6) input signal is asserted. All other key sources use digital modulation automatically. In this mode, Carrier Detect output and the LINK LED are asserted based only on detection of digital modulation. The PTT asserted condition is defined by the PTTSIG command. Entering PTTSIG HI configures the system for an active high Push-to-Talk signal. Entering PTTSIG LO configures the system for an active low Push-to-Talk signal. Entering PTTSIG OFF disables the Push-to-Talk inputuseful for RX audio monitoring of the channel when no TX analog transmission is desired. Analog operating characteristics (selected either by PTT assertion or the MODEM NONE command) vary based on channel type. As a simple rule, SD characteristics associated with MODEM NONE are driven by the last digital modem selection. For example, if MODEM 9600 is selected followed by MODEM NONE, the characteristics for analog oper-

ation match the corresponding 12.5 kHz FCC/IC channel constraints. If MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 47 MODEM 9600M is selected followed by MODEM NONE, analog operation conforms to the channel constraints for a 12.5 kHz ETSI-compliant channel. Table 15 defines the relationship between digital modem selec-

tion and analog operation. Table 15. Relationship Between Digital Modem Selection and Analog Operation Command Command Agency Compliance Analog Chan. Size Peak Deviation MODEM 19200 followed by... MODEM NONE FCC/IC 25.0KHz 5.0 kHz MODEM 9600 followed by... MODEM NONE FCC/IC 12.5KHz 2.5 kHz MODEM 9600M followed by... MODEM NONE ETSI 12.5KHz 2.0 kHz MODEM 4800 followed by... MODEM NONE ETSI 12.5KHz 2.0 kHz Modem transmission/reception characteristics are further qualified by the EMP (emphasis) command. When EMP ON is entered, pre-emphasis is applied on the transmitter and de-emphasis is applied on the receiver. This setting is typically used in operation with voice radios. To disable emphasis, select EMP OFF. Audio signal levels are governed by the RXLEVEL and TXLEVEL com-

mands. Both commands support a range from -20 dBm to 0 dBm. For RX operation, this means that a received signal at the peak deviation will be scaled to the specified RXLEVEL. For TX operation, this means that a transmit input signal of the specified TXLEVEL will translate into the specified peak deviation for transmit. Note that TXLEVEL can also be set to AUTO to automatically scale the input to the target deviation. Values outside the expected range will cause clipping of the RF signal. By default, built-in squelch thresholds automatically mute the receive audio when a signal is not present. To bypass the squelch controls, enter the command SQUELCH BYPASSED. To restore normal operation, enter the command SQUELCH AUTO. 8.5 Upgrading the Radios Firmware From time to time, GE MDS releases new firmware for its radio prod-

ucts to take advantage of engineering improvements or to add opera-

tional features. New firmware can be installed into existing radios in the field, bringing them up to date with the firmware shipped with new units. Firmware files are available free of charge online at:

www.gemds.com/app/support/downloads NOTE: Only firmware specifically designed for this model of radio can be installed in the unit. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 48 Three methods can be used to load new firmware into the radio: Web reprogramming, TFTP, and Serial Transfer. Firmware reprogram-

ming is best handled using the web-based Device Manager. Instructions for these methods of transfer are given below, beginning with Web pro-

gramming. Web Method Determining Current Firmware Version This screen shows Bootloader version information and indicates which firmware image (1 or 2) is currently active, as well as the firmware ver-

sion of each image. The information on this screen is read-only. RefreshClicking this button updates the displayed information on demand. AutoInitiates automatic updating of the information. A time (in seconds) may be entered in the box provided, to specify how often the display is updated. NOTE: The latest firmware version for this product can be obtained at www.gemds.com. Web Reprogramming In the space provided, enter the *.mpk file to reprogram into this radio, then click Program to start the file upload process. Do not click away from this page until the upload has finished processing. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 49 TFTP Method What You Will Need To install firmware by TFTP, you will need:

1. A valid firmware file (see web address above). This will be a file with a .mpk extension. 2. A PC equipped with Telnet, and a TFTP server running on the same computer where the .mpk file is located (a Windows-based TFTP server can be downloaded from the GE MDS Web site at:

www.gemds.com/Resources/TechnicalSupport). 3. The IP address of the PC running the TFTP server. If you do not know your computers IP address, use the RUN function from the Start menu and enter cmd to invoke the Windows Command Inter-

preter. At the > prompt, enter ipconfig to determine the address. 4. The IP address of the radio (the radios IP address can be found by entering the ipconfig command with a serial command line session at the radio). Connecting the Transceiver for Firmware Upgrade There are several alternatives to connecting the transceiver for firmware upgrade. Figure 20 and Figure 21 show two common methods. It is essential that all of the equipment be on the same subnet. LOCAL PC WITH FIRMWARE FILE Invisible place holder TRANSCEIVER T P F T S E R V E R

Firmware Upgrade SetupOption 2

(TFTP Server and Firmware File Must Reside on Same Computer) Upgrade Procedure

(TFTP) To load a new firmware file (filename.mpk) into the transceiver via TFTP, follow these steps:

1. Connect an Ethernet cable between the radios LAN port and the PC

(refer to Figure 20 or Figure 21, as applicable). Verify that the yellow LED on the radios LAN port lights and stays lit. This verifies that the network is functioning. 2. Launch the TFTP server on the PC. If using the GE MDS TFTP Server, click the Options tab (A in Figure 22 below) and modify the Outgoing path (B) using your browser to point to the folder where the reprogramming package (.mpk file) is located. The path (C) will be displayed once the operation is completed. Leave the application running until reprogramming on the radio is complete. Figure 22. TFTP Server Screen

(GE MDS Server shown) 3. Launch a Telnet session and connect to the radio using its pro-

grammed IP address (the radio and PC must be on the same IP net-

work to connect via Telnet). MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 51 4. Use the tftp command to configure the IP host and file to program. For example:

>tftp host 10.4.147.63

>tftp file SDx-3_0_0 5. Enter tftp get to begin reprogramming. The file is loaded into the radios inactive image. A series of progress messages display every few seconds indicating the reprogramming status, followed by Reprogramming Complete when the process is finished. 6. Reboot the radio to the other image using the boot other command.

(At the Are you sure? message, make sure to enter y within 5 seconds or the operation will be cancelled and you will be returned to the >

prompt.) After y is pressed, the message Rebooting to image... will be shown. NOTE: Rebooting ends the current Telnet session. Reestablish a new Telnet connection and proceed with the step below. 7. Enter the SREV command to verify the radio is running the new application image. This completes the TFTP upgrade procedure. NOTE: If a firmware installation fails, the radio is left with the original active image intact, and the inactive image will be unusable. Reprogramming should be attempted again. Serial Transfer Method Firmware upgrade via serial transfer is an alternative method which takes longer to complete than TFTP, but accomplishes the same result. This method is typically used when an Ethernet connection to a PC is not available. What You Will Need To install firmware by serial transfer, you will need:

1. A valid firmware file (see web address given under Upgrading the Radios Firmware on Page 48). This will be a file with an .s28 extension. 2. A PC equipped with a terminal program, such as HyperTerminal

(included with many pre-Vista PCs). Connecting the Transceiver for Firmware Upgrade Connect a PC to the radios COM1 Serial connector as shown in Figure 23 to prepare for firmware upgrade. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 52 Invisible place holder Transceiver PC Running Terminal Session DB-9M to COM1 Port Figure 23. PC Connection to Transceiver (Serial) Follow the steps below for serial transfer upgrade. NOTE: Serial reprogramming takes several minutes at 115200 bps baud rate (the recommended speed), but reprogramming is possible at lower baud rates. 1. Launch a terminal session to the radio with the following communications parameters: Baud 115200, 8 data bits, no parity, one stop bit (8N1), XON/XOFF flow control, and VT100 emulation. 2. At the > prompt, enter program. At the ARE YOU SURE? prompt, enter yes. 3. At the LOADER> prompt, enter erase. The response ERASED OK is returned. 4. At the LOADER> prompt, enter program. Do not type any more char-

acters at the prompt. 5. From the terminal program, quickly select Transfer->Send Text File and choose the correct file/file folder on the PC where the .s28 firm-

ware file is located. This process initiates the file transfer and causes the radio to repro-

gram the inactive image. When using HyperTerminal to perform reprogramming, no status indication is available. 6. Programming is complete when PROGRAMMED OK appears at the prompt. The active image has now been changed to the new package. If this message is not seen, reprogramming did not com-

plete successfully and must be attempted again. 7. Reboot the unit by typing the exit command at the LOADER> prompt. This completes the serial upgrade procedure. To verify that the radio is running the newly loaded firmware image, enter the srev com-

mand after rebooting. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 53 NOTE: If a firmware installation fails, the radio is left with the original active image intact, and the inactive image will be unusable. Reprogramming should be attempted again. Error Messages During File Transfers It is possible to encounter errors during a file transfer. In most cases errors can be quickly corrected by referring to Table 16. Table 16. Common Errors During TFTP Transfer Error Message Invalid File Type File not found Invalid file path Timeout Bad CRC Likely Cause/Corrective Action Indicates that the file is not a valid firmware file. Locate proper file and re-load. Invalid or non-existent filename on TFTP server Invalid or non-existent file path to TFTP server TFTP transfer time expired. Increase the timeout value. Cyclic Redundancy Check reporting a corrupted file. Attempt to re-load, or use a different file. Version String Mismatch Invalid file detected. Attempt to re-load, or use a different file.

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 SCADA system polling communications (contrast with pas-

sive messaging). Active (or intrusive) messaging is much faster than passive messaging 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. 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. ByteA string of digital data usually made up of eight data bits and start, stop and parity bits. 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. 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. 56 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E 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. EqualizationThe process of reducing the effects of amplitude, fre-

quency or phase distortion with compensating networks. Fade MarginThe greatest tolerable reduction in average received signal strength to be expected under most conditions. Provides an allow-

ance 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. 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. 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 station site, which controls the collection of data from one or more remote sites. 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. 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. MASMultiple Address System. A radio system where a central master station communicates with several remote stations for the pur-

pose 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. Non-intrusive diagnosticsSee Passive messaging. MDS 05-4670A01, Rev. E SD Series Reference Manual (x710 Mode) 57 Passive messagingThis is a mode of diagnostic gathering that does not interrupt SCADA system polling communications. Diagnostic data is collected non-intrusively over a period of time; polling messages are carried with SCADA system data (contrast with active messaging). Payload dataThis is the applications user communication data which is sent over the radio network. 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. Programmable Logic ControllerSee PLC. Remote (Station)A radio in a network that communicates with an associated master station. 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. 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. SCADASupervisory Control And Data Acquisition. An overall term for the functions commonly provided through an MAS radio system. 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). 58 SD Series Reference Manual (x710 Mode) MDS 05-4670A01, Rev. E NOTES MDS 05-4670A01, Rev.

*Note: ______(Insert Explanation as Necessary)______ GE MDS LLC has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality:

The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: Long term requested The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of NA days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify ACB in the event information regarding the product or the product is made available to the public. ACB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705. NOTE for Industry Canada Applications:

The applicant understands that until such time that IC distinguishes between Short Term and Permanent Confidentiality, either type of marked exhibit above will simply be marked Confidential when submitted to IC. Sincerely, By:

(Signature/Title) 1 - The asterisked items (*) require further justification before permanent confidentiality will be allowed. These also currently require review by the FCC under their Permit-But-Ask policy before the grant is issued and can delay completion of an application. Further justification should be added to the note above. One such example for a potted device would be: The EUT is FULLY potted using a non-removable epoxy based material. Removal of potting material causes irreparable damage to internal circuitry. See photographs exhibits that outline the device before and after potting. 022311 6

Product: MDS SD4 FCC ID: E5MDS-SD4 Dear Sir/Madam, The SD4 is a multi-modem system operating between 350-512MHz, in channel bandwidths of 6.25kHz, 12.5kHz, and 25.0kHz. Modulation is CPFSK, OTA data rate and maximum ERP power is based on the FCC ULS user site license. The SD4 covers 350-512MHz. This device is designed to operate from 350-512MHz, but is limited by the device software to ensure operation only between the desired bands, which are by allowed by FCC rules. FCC bands B&C cover the 406.1-512MHz range, The SD4 is approved under part 90 and part 22 A = 350.0 to 400.0MHz B = 400.0 to 450.0MHz C = 450.0 to 512.0MHz D = 300.0 to 360.0MHz FCC rules are violated if the device operates on unauthorized frequencies. This letter serves as attestation supporting evidence for the frequency banding. If you have any queries, please do not hesitate to contact me at 585 734-3899:
