QUICK START GUIDE Below are the basic steps for installing the transceiver. Detailed instructions are given in ÒINSTALLA-TIONÓ on page 9 of this guide. 1. Install and connect the antenna system to the radio ¥ Use good quality, low loss coaxial cable. Keep the feedline as short as possible.¥ Preset directional antennas in the direction of desired transmission. 2. Connect the data equipment to the radioÕs INTERFACE connector ¥ Connection to the radio must be made with a DB-25 Male connector. Connections for typical sys-tems are shown below. ¥ Connect only the required pins. Do not use a straight-through RS-232 cable with all pins wired.¥ Verify the data equipment is conÞgured as DTE. (By default, the radio is conÞgured as DCE.) 3. Apply DC power to the radio (10.5Ð16 Vdc @ 2.5 A minimum) ¥ Observe proper polarity. The red wire is the positive lead; the black is negative. 4. Set the radioÕs basic conÞguration with a Hand-Held Terminal (HHT) ¥ Set the transmit frequency ( TX xxx.xxxx ).¥ Set the receive frequency ( RX xxx.xxxx ).¥ Set the baud rate/data interface parameters as follows. Use the BAUD xxxxx abc command, where xxxxx equals the data speed (110Ð38400 bps) and abc equals the communication parameters as follows: a = Data bits (7 or 8) b = Parity (N for None, O for Odd, E for Even c = Stop bits (1 or 2)(Example: BAUD 9600 8N1 )NOTE: 7N1, 8E2 and 8O2 are invalid parameters and are not supported by the transceiver. 5. Verify proper operation by observing the LED display ¥ Refer to Table 4 on page 14 for a description of the status LEDs.¥ ReÞne directional antenna headings for maximum receive signal strength using the RSSI command.

MDS 05-3305A01, Rev. A MDS 4710A/9710A Installation and Operation Guide 1 1.0 GENERAL 1.1 Introduction This guide presents installation and operating instructions for the MDS 4710A/9710A (400/900 MHz) digital radio transceivers.These transceivers (Figure 1) are data telemetry radios designed to operate in a point-to-multipoint environment, such as electric utility Supervisory Control and Data Acquisition (SCADA) and distribution automation, lottery systems, gas field automation, water and wastewater SCADA, and on-line transaction processing applications. They use microprocessor control and Digital Signal Processing (DSP) technology to provide highly reliable communications even under adverse condi-tions.MDS 4710A/9710A radios use continuous-phase frequency (CPFSK) modulation with root duo-binary filtering (the sum of two Nyquist-shaped, root-raised cosine responses). Demodulation uses a Virterbi decoder and equalization with soft decision decoding.Modulation and demodulation is accomplished using Digital Signal Pro-cessing (DSP). DSP adapts to differences between components from unit to unit, and ensures consistent and repeatable performance in ambient temperatures from Ð30 to +60 degrees Centigrade. The use of Digital Signal Processing eliminates the fluctuations and variations in modem operation that degrade operation of analog circuits.The transceiver is designed for trouble-free operation with data equip-ment provided by other manufacturers, including Remote Terminal Units (RTUs), flow computers, lottery terminals, automatic teller machines, programmable logic controllers, and others. NOTE: Some features may not be available on all radios, based on theoptions purchased and based on the applicable regulatory constraints for the region in which the radio will operate.
2 MDS 4710A/9710A Installation and Operation Guide MDS 05-3305A01, Rev. A Invisible place holder Figure 1. Transceiver Connectors and Indicators 1.2 Applications Point-to-Multipoint, Multiple Address Systems (MAS) This is the most common application of the transceiver. It consists of a central master station and several associated remote units as shown in Figure 2. An MAS network provides communications 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, however, a radio system consists of many widely separated remote radios. A point-to-multipoint or SCADA (Supervisory Control and Data Acquisition) system may be a new installation for automatic, remote monitoring of gas wells, water tank levels, electric power distri-bution system control and measurement, etc.The radio system may replace a network of remote monitors currently linked to a central location via leased telephone line. At the central office of such a system, there is usually a large mainframe computer and some means of switching between individual 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, a desirable alternative may be replacing the phone line with a radio path.EXTERNAL INTERFACECONNECTOR(DB-25)DIAGNOSTICS CONNECTOR (RJ-11)13.8 VDC POWER CONNECTORANTENNA CONNECTOR(TYPE ÒNÓ)SERIAL NUMBERLABELLED INDICATORS (4)

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 radiosÑone serving as a master and the other as a remoteÑas shown in Figure 3. It provides a simplex or half-duplex communications link for the transfer of data between two locations. Invisible place holder Figure 3. Typical Point-to-Point Link Continuously Keyed versus Switched Carrier Operation The keying behavior of the master station can be used to describe 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 simultaneously transmitting and continuously listening. Different frequencies must be used for transmit and receive. This is the method used in many MAS systems, and is shown in Figure 2. This is useful for high-speed polling applica-tions.ÐIDIAG13.8 VDCPWR+ ÐHOST SYSTEMREMOTE RADIORTURTURTURTUÐIDIAG13.8 VDCPWR+ ÐÐIDIAG13.8 VDCPWR+ ÐÐIDIAG13.8 VDCPWR+ ÐÐIDIAG13.8 VDCPWR+ ÐRTUMDS MASTERSTATIONCONTINUOUSLYKEYEDREMOTE RADIOREMOTE RADIOREMOTE RADIOREMOTE RADIOREMOTEMASTERHOSTCOMPUTERRTU
4 MDS 4710A/9710A Installation and Operation Guide MDS 05-3305A01, Rev. A NOTE: 4710A/9710A remotes do not support full-duplex operation. 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 that data turn-around times are increased when a single frequency configuration is used. 1.3 Model Number Codes The radio model number is printed on the end of the radio enclosure, and provides key information about how the radio was configured when it was shipped from the factory.

6 MDS 4710A/9710A Installation and Operation Guide MDS 05-3305A01, Rev. A 2.0 GLOSSARY OF TERMS 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 Messaging ÑThis 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 Gain ÑA 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. Bit ÑThe 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-second ÑSee BPS . BPS ÑBits-per-second. A measure of the information transfer rate of digital data across a communication channel. Byte ÑA string of digital data usually made up of eight data bits and start, stop and parity bits. Decibel (dB) ÑA measure computed from the ratio between two signal levels. Frequently used to express the gain (or loss) of a system. Data Circuit-terminating Equipment ÑSee DCE . Data Communications Equipment ÑSee DCE . Data Terminal Equipment ÑSee DTE . dBi ÑDecibels referenced to an ÒidealÓ isotropic radiator in free space. Frequently used to express antenna gain. dBm ÑDecibels referenced to one milliwatt. An absolute unit used to measure signal power, as in transmitter power output, or received signal strength. DCE ÑData Circuit-terminating Equipment (or Data Communications Equipment). In data communications terminology, this is the ÒmodemÓ side of a computer-to-modem connection. The MDS 4710A/9710A is a DCE device. Digital Signal Processing ÑSee DSP .
MDS 05-3305A01, Rev. A MDS 4710A/9710A Installation and Operation Guide 7 DSP ÑDigital Signal Processing. In the MDS 4710A/9710A trans-ceiver, the DSP circuitry is responsible for the most critical real-time tasks; primarily modulation, demodulation, and servicing of the data port. DTE ÑData Terminal Equipment. A device that provides data in the form of digital signals at its output. Connects to the DCE device. Equalization ÑThe process of reducing the effects of amplitude, fre-quency or phase distortion with compensating networks. Fade Margin ÑThe greatest tolerable reduction in average received signal strength that will be anticipated under most conditions. Provides an allowance for reduced signal strength due to multipath, slight antenna movement or changing atmospheric losses. A fade margin of 20 to 30 dB is usually sufficient in most systems. Frame ÑA 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 Control ÑA 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 Computer ÑThe computer installed at the master station site, which controls the collection of data from one or more remote sites. Intrusive Diagnostics ÑA mode of remote diagnostics that queries and commands radios in a network with an impact on the delivery of the system ÒpayloadÓ data. See Active messaging . Latency ÑThe 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. MAS ÑMultiple 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) ÑRadio which is connected to the host computer. It is the point at which polling enters the network. MCU ÑMicrocontroller Unit. This is the processor responsible for con-trolling system start-up, synthesizer loading, and key-up control. Microcontroller Unit ÑSee MCU .
8 MDS 4710A/9710A Installation and Operation Guide MDS 05-3305A01, Rev. A Multiple Address System ÑSee MAS . Network-Wide Diagnostics ÑAn advanced method of controlling and interrogating MDS radios in a radio network. Non-intrusive diagnostics ÑSee Passive messaging . Passive messaging ÑThis 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 data ÑThis is the applicationÕs user communication data which is sent over the radio network. It is the transfer of payload data that is the primary purpose of the radio communications network. Point-Multipoint System ÑA radio communications network or system designed with a central control station that exchanges data with a number of remote locations equipped with terminal equipment. PollÑA request for data issued from the host computer (or master PLC) to a remote radio.PLCÑProgrammable 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 ControllerÑSee PLC.Remote (Station)ÑA radio in a network that communicates with an associated master station.Remote Terminal UnitÑSee RTU.Redundant OperationÑA station arrangement where two transceivers and two power supplies are available for operation, with automatic switchover in case of a failure.RTUÑRemote Terminal Unit. A data collection device installed at a remote radio site. An internal RTU simulator is provided with 4710/9710 radios to isolate faults to either the external RTU or the radio.SCADAÑSupervisory Control And Data Acquisition. An overall term for the functions commonly provided through an MAS radio system.Standing Wave RatioÑSee SWR.Supervisory Control And Data AcquisitionÑSee SCADA.
MDS 05-3305A01, Rev. A MDS 4710A/9710A Installation and Operation Guide 9SWRÑStanding 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).3.0 INSTALLATIONThere are three main requirements for installing the transceiverÑade-quate and stable primary power, a good antenna system, and the correct data connections between the transceiver and the data device. Figure 6 shows a typical remote station arrangement.Invisible place holderFigure 6. Typical Remote Station Arrangement3.1 Installation StepsBelow are the basic steps for installing the transceiver. In most cases, these steps alone are sufficient to complete the installation. More detailed explanations appear at the end of these steps.1. Mount the transceiver to a stable surface using the brackets supplied with the radio.2. Install the antenna and antenna feedline for the station.

Use only the required pins for the applicationÑDo not use a fully pinned (25 conductor) cable. Basic applications may require only the use of Pin 2 (transmit dataÑTXD), Pin 3 (Received DataÑRXD) and Pin 7 (signal ground). The radio can be keyed with the use of the DATAKEY command.Additional connections may be required for some installations. Refer to the complete list of pin functions provided in Table 4 on page 14.4. Measure and install the primary power for the radio. The red wire on the power cable is the positive lead; the black is negative.NOTE: Use the radio in negative ground systems only.5. Set the radio conÞguration. The transceiver is designed for quick installation with a minimum of software conÞguration required in most cases. The selections that must be made for new installations are:¥ Transmit frequency¥ Receive frequencyThe operating frequencies are not set at the factory unless they were speciÞed at the time of order. Determine the transmit and receive frequencies to be used, and follow the steps below to program them.6. Connect a hand-held terminal (HHT) to the DIAG. connector. When the HHT beeps, press to receive the ready Ò>Ó prompt.a. Set the operating frequencies using the TX xxx.xxxx (transmit) and RX xxx.xxxx (receive) commands.Press after each command. After programming, the HHT reads PROGRAMMED OK to indicate successful entry.ENTERENTER

Transceiver Mounting Dimensions3.3 Antennas and FeedlinesAntennasThe transceiver can be used with a number of antennas. The exact style depends on the physical size and layout of the radio system. A direc-tional Yagi (Figure 8) 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.8.5"216 mm1.75"4.44 CM6.63"168 mm2.75"70 mm7.25"184 mmALTERNATEPOSITION5.625"143 mm2.25"57 mm2.0"50 mm

Typical Yagi Antenna (mounted to mast)FeedlinesThe selection of antenna feedline is very important. Poor quality cables should be avoided as they will result in power losses that may reduce the range and reliability of the radio system.Table 2 and Table 3 show the losses that will occur when using various lengths and types of cable at 400 and 960 MHz. Regardless of the type of cable used, it should be kept as short as possible to minimize signal loss.Table 2.

MDS 05-3305A01, Rev. A MDS 4710A/9710A Installation and Operation Guide 133.4 Power ConnectionThe transceiver can be operated from any well-filtered 10.5 to 16 Vdc power source. The power supply should be capable of providing at least 2.5 amperes of continuous current.The red wire on the power cable is the positive lead; the black is nega-tive.NOTE: The radio is designed for use only in negative ground systems.3.5 Data Interface ConnectionsThe transceiverÕs DATA INTERFACE connector is used to connect the transceiver to an external DTE data terminal that supports the EIA-232 (formally RS-232) format. The transceiver supports asynchronous data rates of up to 38400 bps. The data rate at the DATA INTERFACE connector may differ from the data rate used over the air.Table 4 lists each pin on the DATA INTERFACE connector and describes its function.Do not use a 25 wire (fully pinned) cable for connection to the DATA INTERFACE connector. Use only the required pins for the application. Damage may result if improper connections are made. Typical applica-tions require the use of only Pins 1 through 8 for EIA-232 signaling.3.6 Using the RadioÕs Sleep ModeIn some installations, such as at solar-powered sites, it may be necessary to keep the transceiverÕs power consumption to an absolute minimum. This can be accomplished using the Sleep Mode. In this mode, power consumption is reduced to less than 16 milliamperes (nominal).Sleep mode can be enabled under RTU control by asserting a ground (or RS-232 low) on Pin 12 of the radioÕs DATA INTERFACE connector.When Pin 12 is opened (or an RS-232 high is asserted), the radio will be ready to receive data within 75 milliseconds.All normal functions are suspended while the radio is in sleep mode. The PWR LED will be off, except for a quick flash every five seconds.System ExampleThe following example describes Sleep Mode implementation in a typ-ical system. Using this information, you should be able to configure a system that will meet your own particular needs.CAUTIONUSEONLY REQUIREDPINS
14 MDS 4710A/9710A Installation and Operation Guide MDS 05-3305A01, Rev. AExample:Suppose you need communications to each remote site only once per hour. Program the RTU to raise an RS-232 line once each hour (DTR for example) and wait for a poll and response before lowering it again. Connect this line to Pin 12 of the radioÕs DATA INTERFACE connector. This will allow each RTU to be polled once per hour with a significant savings in power con-sumption.Table 4.

MDS 05-3305A01, Rev. A MDS 4710A/9710A Installation and Operation Guide 23AMASK [0000 0000ÐFFFF FFFF]The AMASK command displays or sets which events cause the 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 is used to classify up to 32 events as alarm triggers, or disable alarm noti-fication for an event. (See Table 8 below for a list of events.) The hex value for the mask corresponds to the hex value for the STAT command (page 30). Each bit that is a Ô1Õ identifies the associated alarm condition as a major alarm. Each bit that is a Ô0Õ disables major alarm notification for that condition. If both the major and minor alarm bits are set to Ô0Õ for that condition, alarm notification is entirely disabled.

24 MDS 4710A/9710A Installation and Operation Guide MDS 05-3305A01, Rev. AASENSE [HI/LO]The ASENSE command sets or displays the sense of the alarm output at Pin 25 of the DATA INTERFACE connector.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.BAUD [xxxxx abc]This command sets (or displays) the communication attributes for the DATA INTERFACE port. It has no effect on the RJ-11 DIAG. 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: 110, 300, 1200, 2400, 4800, 9600, 19200, or 38400.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 19200 baud, 8 data bits, no parity, 1 stop bit (Example: 19200 8N1).NOTE: 7N1, 8O2, and 8E2 are invalid communication settings and arenot supported by the transceiver.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 out the 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 thus sent out the INTERFACE port as soon as an incoming RF data frame is disassembled. Average and typical latency will both be below 10 ms, but idle character gaps may be intro-duced into the outgoing data flow.If data buffering is ON, the radio operates in seamless mode. Data bytes will be 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 MODBUSª that do not allow gaps in their data transmission.
MDS 05-3305A01, Rev. A MDS 4710A/9710A Installation and Operation Guide 25Note that seamless mode (BUFF ON) is intended only for applications where the transmitterÕs baud rate is greater than or equal to the receiverÕs baud rate. Enforcement of this rule is left up to the user.CKEY [ONÐOFF]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.CTS [0Ð255]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 out the DATA INTERFACE port. A timer value of zero means that data will be sent out the data port without imposing a key-up delay. (Other delays may be present based on selected radio operating parameters.)DATAKEY [ON, OFF]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 transceiverÕs DATA INTERFACE connector. If DATAKEY is set to OFF, the radio needs to be keyed by asserting either the RTS or PTT signal or with the CKEY or KEY command.DEVICE [DCE, CTS KEY]The DEVICE command controls or displays the device behavior of the radio. The command parameter is either DCE or CTS KEY.The default selection is DCE. In this mode, CTS will go high following RTS, subject to the CTS programmable delay time. If the DATAKEY com-mand 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.
26 MDS 4710A/9710A Installation and Operation Guide MDS 05-3305A01, Rev. AIf CTS KEY is selected, the radio is assumed to be controlling another radio. The RTS line is ignored and the CTS line is used as a keyline con-trol 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.)DKEYThis command deactivates the transmitter after it has been keyed with the KEY command.DLINK [ON/OFF/xxxx]This command is used 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).DMGAP [xx]The DMGAP command sets the amount of time in milliseconds to wait after the receipt of a character before interpreting the next received char-acter as the start of a new message. When data port baud rates are slow, the gap between characters within a poll may be so long that the radio interprets the next character as the start of a new poll. When diagnostics is being performed using passive messaging (see Performing Net-work-Wide Remote Diagnostics on page 37), this command may be used to change this behavior.DTYPE [NODE/ROOT]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. See ÒPerforming Network-Wide Remote DiagnosticsÓ on page 37.DUMPThis command displays all the programmed settings with this one com-mand. The HHT display is too small to list all the command settings at one time. Therefore, this command is most useful if the command is issued from a computer or full-screen terminal.HREVThis command displays the transceiverÕs hardware revision level.
MDS 05-3305A01, Rev. A MDS 4710A/9710A Installation and Operation Guide 27INITThe INIT command is used to re-initialize the radioÕs operating parame-ters to the factory defaults. This may be helpful when trying to resolve configuration problems that may have resulted from the entry of one or more improper command settings. If you are unsure of which command setting may have caused the problem, this command allows you to get back to a known working state.

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]This command selects or displays the radioÕs receive frequency in MHz. The frequency step size is 6.25 kHz.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.NOTE: A large change in receive frequency (more than 5 MHz)requires adjustment of the receiver helical filters for maximumperformance and RSSI. See Section 7.2, Helical Filter Adjust-ment (page 36) for details.RXTOT [NONE, 1-255]The RXTOT command selects or displays 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 displays the timer value in minutes. Entering the RXTOT command with a parameter ranging from 0 to 255 resets the timer in minutes. Entering the RXTOT command with the parameter NONE disables the timer.SCD [0-255]This command displays 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.SERThis command displays the radioÕs serial number as recorded at the fac-tory.
30 MDS 4710A/9710A Installation and Operation Guide MDS 05-3305A01, Rev. ASHOW [DC, PORT, PWR]The SHOW command displays different types of information based on the command variables. The different parameters are:¥DCÑDisplay DC input/output voltages¥PORTÑDisplay the connector port (RJ-11 or DB-25) that is active for diagnostics and control.¥PWRÑDisplay RF power outputSNRThis command continuously displays 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.The SNR is an indication of the received signal quality. The SNR indi-cation ranges from 10 dB to 33 dB. 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 key is pressed.SREVThis command displays the software revision level of the transceiver firmware.STATThis command displays the current alarm status of the transceiver.If no alarms exist, the message NO ALARMS PRESENT appears at the top of the HHT display.If an alarm does exist, a two-digit code (00Ð31) is displayed and the alarm is identified as ÒMajorÓ or ÒMinor.Ó 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.

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]This command selects or displays the radioÕs transmit frequency in MHz. The frequency step size is 6.25 kHz.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.UNIT [10000...65000]The unit address is factory programmed to the last five digits of the serial number. 6.0 TROUBLESHOOTINGSuccessful 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 can 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 (4A).

A6.1 LED IndicatorsThe LED status indicators are an important troubleshooting tool and should be checked whenever a problem is suspected. Table 5 on page 16 describes the function of each status LED.6.2 Event CodesWhen an alarm condition exists, the transceiver creates a code that can be read on an HHT connected to the DIAG. port. These codes can be very helpful in resolving many system difficulties. Refer to Table 9 (page 33) for a definition of the event codes.Checking for AlarmsÑSTAT commandTo check for alarms, enter STAT on the HHT. If no alarms exist, the mes-sage NO ALARMS PRESENT appears at the top of the display (Figure 12).Invisible place holderFigure 12. HHT Display in Response to STAT CommandIf an alarm does exist, a two-digit alarm code (00Ð31) is displayed and the event is identified as a Major or Minor Alarm. A brief description of the alarm is also given.If more than one alarm exists, the word MORE appears at the bottom of the screen. To view additional alarms, press .Major Alarms vs. Minor AlarmsMajor AlarmsÑreport 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 MDS for further assistance.Minor AlarmsÑreport conditions that, under most circumstances will not prevent transceiver operation. This includes out-of-tolerance condi-tions, baud rate mismatches, etc. The cause of these alarms should be investigated and corrected to prevent system failure.ENTER

Apply a steady signal to the radio at the programmed receive fre-quency (Ð80 dBm level recommended; no stronger than Ð60 dBm). This can be done with a signal generator or an over-the-air signal.4. Measure the radioÕs RSSI using one of the following methods:¥ With an HHT (See Section 5.0, TRANSCEIVER PROGRAM-MING on page 17).¥ With MDS Radio Configuration Software (See Section 7.4, Upgrading the RadioÕs Software on page 39).¥ With a voltmeter connected to Pin 21 of the DATA INTERFACE connector (See Section 4.2, RSSI Measurement on page 16).5. With a non-metallic adjustment tool, adjust each section of the helical Þlters for maximum RSSI. Re-install the cover to the trans-ceiver.Invisible place holderFigure 13.

Network-Wide Remote Diagnostics SetupIf 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 ÒrootÓ 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 MDSÕ Network-Wide Diagnostics System Handbook. See the Handbook for more information about the basic diagnostic procedures outlined below.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 conÞgure the diagnostic link protocol on the RJ-11 port.3. Program all other radios in the network as nodes by entering the DTYPE NODE command at each radio.RTUDIAGNOSTICS DATA(TO InSite)HOST COMPUTERRTU TODIAGNOSTICSPORTTO DATAPORTMASTER STATIONROOTDTYPEROOTPAYLOAD DATA(TO SCADA APPLICATION)RTUDTYPENODEDTYPENODEDTYPENODE

Use the DLINK ON and DLINK [baud rate] commands to conÞgure the diagnostic link protocol on the RJ-11 port of each node radio.5. Connect same-site radios using a null-modem cable at the radiosÕ diagnostic ports.6. Connect a PC on which MDS InSite software is installed to the root radio, or to one of the nodes, at the radioÕs diagnostic port. (This PC may be the PC being used to collect payload data, as shown in Figure 14.)To connect a PC to the radioÕs DIAG. port, an RJ-11 to DB-9 adapter (MDS P/N 03-3246A01) is required. If desired, an adapter cable may be constructed from scratch using the information shown in Figure 15.Invisible place holderFigure 15. RJ-11 to DB-9 Adapter Cable7. Launch the MDS InSite application at the PC. (See the MDS InSite UserÕs Guide for instructions.)7.4 Upgrading the RadioÕs SoftwareWindows-based Radio Configuration software is available (MDS P/N 03-3156A01) for upgrading the internal radio software when new fea-tures become available from Microwave Data Systems. Contact MDS for ordering information.To connect a PC to the radioÕs DIAG. port, an RJ-11 to DB-9 adapter (MDS P/N 03-3246A01) is required. If desired, an adapter cable may be constructed from scratch using the information shown in Figure 15.Using the Radio Configuration software, select RADIO SOFTWARE UPGRADE under the SYSTEM menu. Follow the prompts and online instructions to determine how to proceed.Software upgrades are distributed as ASCII files with a Ò.S28Ó exten-sion. These files use the Motorola S-record format. When the download is activated, the radioÕs PWR LED will flash rapidly, confirming that a download is in process.
