Antenna Installation Warning
1.All antenna installation and servicing is to be performed by
qualified technical personnel only. When servicing the antenna, or
working at distances closer than those listed below, ensure the
transmitter has been disabled.
Output is measured at the antenna terminal of the transmitter. The
antenna(s) used for this transmitter must be fixed-mounted on
outdoor permanent structures to provide the minimum separation
distances described in this filing for satisfying RF exposure
compliance requirements. When applicable, RF exposure
compliance may need to be addressed at the time of licensing, as
required by the responsible FCC Bureau(s), including antenna
co-location requirements of §1.1307(b)(3).
2.Typically, the antenna connected to the transmitter is a directional
(high gain) antenna, fixed-mounted on the side or top of a building,
or on a tower. Depending upon the application and the gain of the
antenna, the total composite power could exceed 200 watts EIRP.
The antenna location should be such that only qualified technical
personnel can access it, and that under normal operating conditions
no other person can touch the antenna or approach within 3.05 meters of the antenna.

SERIAL NUMBER
1.1Introduction
This guide presents installation and operating instructions for the
1710A/2710A/4710A/9710A and 1710C/2710C/4710C/9710C
Series (150/230/350/400/900 MHz)
These transceivers (Figure1) 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, gas field automation, water and wastewater SCADA, and
online transaction processing applications. They use microprocessor
control and Digital Signal Processing (DSP) technology to provide
highly reliable communications under adverse conditions.
X710A/C radios use continuous-phase frequency shift keying
(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 Processing (DSP). DSP adapts to differences between components from
unit to unit, and ensures consistent and repeatable performance in
ambient temperatures from –40 to +70 degrees Celsius. 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 equipment provided by other manufacturers, including Remote Terminal
Units (RTUs), flow computers, lottery terminals, automatic teller
machines, programmable logic controllers, and others.

NOTE: Some features are not available on all radios, based on the
options purchased and the applicable regulatory constraints for
the region in which the radio operates.
1.2Applications
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
Figure2. A 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, however, a radio system consists of many widely separated
remote radios. A point-to-multipoint or SCADA (Supervisory Control
and Data Acquisition) system might be utilized for automatic, remote
monitoring of gas wells, water tank levels, electric power distribution
system control and measurement, and so on.
The radio system can 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
a way to switch 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 is to replace the phone line with
a radio path.

Point-to-Point System
REMOTE
Where permitted, the transceiver can also be used in a point-to-point
system. A point-to-point system consists of two radios, one serving as a
master and the other as a remote (Figure3). This system provides a sim-
plex or half-duplex communication link for the transfer of data between
two locations.

Figure 3. Typical Point-to-Point Link
Continuously-Keyed versus Switched-Carrier Operation
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 listening. Use different frequencies to transmit and receive. This is
the method used in many MAS systems, as is shown in the typical
system in Figure2. This is network arrangement useful for high-speed
polling applications.
NOTE
1710/2710/4710/9710 remotes do not support full-duplex operation.
Switched-Carrier operation is a half-duplex mode where the master station transmitter is keyed to send data and unkeyed to receive. The transceiver uses different frequencies for transmit and receive. This prevents
different remotes from interfering with each other, making it easier to
implement SCADA protocols. This mode results in slower polling times
than a Continuous-Keyed master due to the keying time for the master
and squelch opening time for the remote.
Additional information:
• Remotes always operate in switched-carrier mode, but can
receive data from a master that operates in either switched-carrier
or continuously-keyed modes.
• A single-frequency system cannot utilize a continuously keyed
master.
• An advantage of a continuously-keyed master is that it provides a
constant signal source to remotes that require a constant Data Carrier Detect signal.
05-3305A01, Rev. E 3
Page 12
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. Simplex mode results in slower polling because the TX synthesizer must move off the RX channel to receive, and back to transmit.
Single-frequency operation is useful for peer-to-peer communication
using omni-directional antennas with radios in close proximity to each
other.
1.3Model Number Codes
The radio model number is printed on the end of the radio enclosure and
provided through the software command MODEL (Page 28). It provides
key information about how the radio was configured when it was
shipped from the factory. This number is subject to many variations
depending on what options are installed, and in which country the
product is used. Contact us if
you have questions on the meaning
of the code.

2.1Installation Steps
Below 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 feedline for the station. Point directional
antennas in the direction of the associated network’s Master Station.
3.Connect the data equipment to the transceiver’s DATA INTERFACE
connector. Use only the required pins for the application—Do not
use a fully pinned (25-conductor) cable. Basic applications might
require only the use of Pin 2 (Transmit Data—TXD), Pin 3
(Received Data—RXD) and Pin 7 (Signal Ground). The radio can
be keyed by using the DATAKEY command.
Additional connections might be required for some installations.
Refer to the complete list of pin functions provided in Table6 on
Page11.

2.3Antennas and Feedlines
Antennas
The transceiver can be used with a number of antenna styles. The exact
style depends on the physical size and layout of the radio system. A
directional Yagi (Figure6) or corner reflector antenna is generally rec-
ommended at remote sites to minimize interference to and from other
users. Antennas of this type are available from several manufacturers.
ײª·-·¾´» °´¿½» ¸±´¼»®
Figure 6. Typical Yagi Antenna (mounted to mast)
Feedlines
The selection of antenna feedline is very important. Avoid poor quality
cables as they will result in power losses that can reduce the range and
reliability of the radio system.
Table4 and Table5 show the losses that will occur when using various
lengths and types of cable at 400 and 960 MHz. Keep the cable as short
as possible to minimize signal loss.

2.4Power Connection
The transceiver is compatible with any well-filtered 10.5 to 16 Vdc
power source. The power supply should be capable of providing at least
2.5 A(for RF 5W) of continuous current.
The red wire on the power cable is the positive lead; the black is negative.
NOTE: The radio is designed for use only in negative ground systems.
2.5Safety/Earth Ground
To minimize the chances of damage to the transceiver and connected
equipment, a good safety ground is recommended which bonds the
antenna system, the radio transceiver, power supply, and connected data
equipment to a single-point ground. Normally, the transceiver is adequately grounded if the mounting brackets are used to secure the radio
to a well-grounded metal surface.
If the transceiver is not mounted to a grounded surface, connect a safety
ground to the transceiver case. A ground can be connected to one of the
four screws on the bottom of the transceiver. Do not use any of the four
screws that hold together the upper and lower parts of the transceiver
case.
Connect all rack equipment and associated hardware grounds to the
building’s ground system for the primary power. The objective is to
create a single-point ground system, keeping all grounds leads as short
as possible.
To prevent damage, provide a good ground connection for the equipment connected to the INTERFACE connector.
Finally, use lightning protectors where the antenna transmission lines
enter the building. Bond them to the tower ground, if it is nearby.

Page 19
2.6Data Interface Connections
Connect the transceiver’s DATA INTERFACE connector to an external
DTE data terminal that supports the EIA-232 (formally RS-232) format.
The transceiver supports autobaud asynchronous data rates of up to
19200 bps. The data rate at the DATA INTERFACE connector might differ
from the data rate used over the air.
Table6 lists and describes each pin on the DATA INTERFACE connector.

2.7Using the Radio’s Sleep Mode
In some installations, such as at solar-powered sites, use Sleep Mode to
keep the transceiver’s power consumption to an absolute minimum. In
Sleep Mode, power consumption is reduced to less than 15 mA (nominal), yet preserves the radio’s ability to be brought online quickly.
All normal functions are suspended while the radio is in Sleep Mode.
The PWR LED is off, except for a quick flash every 5 sec.
12 05-3305A01, Rev. E
Page 21
Enable Sleep Mode through RTU control by asserting a ground on Pin
12 of the radio's DATA INTERFACE connector. When Pin 12 is opened,
the radio will be ready to receive data after a delay period that varies
with modem type. With MODEM NONE, the delay will be less than 75 ms.
Digital modems will typically require an additional 60 to 100 ms to resceive data when receiving a continuous keyed master station. This additional delay is reduced to less than 20 ms when receiving a switch-keyed
master station.
NOTE: Our radio recommends against applying RS-232 voltages to
Pin 12 of the radio’s DB 25 connector. Only apply ground or
+5 Vdc to this pin. Our radio recommends that you connect the
radio and RTU using the circuit shown in Figure7.
For information on using an ABB Totalflow meter to control
the radio’s sleep mode, refer to GE MDS Product BulletinPB-0904.
The following example describes Sleep Mode implementation in a typical system. Use this information to configure a system that meets your
particular needs.
Sleep Mode Example:
You need communication 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 radio’s DATA INTERFACE
connector. This allows each RTU to be polled once per hour with
a significant savings in power consumption.

3.0OPERATION
In-service operation of the transceiver is completely automatic. Once
the unit is properly installed and configured, operator actions are limited
to observing the front panel LED status indicators for proper operation.
05-3305A01, Rev. E 13
Page 22
If all parameters are correctly set, start radio operation by following
these steps:
1.Apply DC power to the transceiver.
2.Observe the LED status panel for the proper indications (Table7).
3.If not done earlier, refine the antenna heading of the station to maximize the received signal strength (RSSI) from the master station.
Use the RSSI command from an HHT or PCconnected to the radio’s
connector. See Section4.0, TRANSCEIVER PROGRAMMING on
Page 15. This can also be done with a DC voltmeter as described in
Section3.2, RSSI Measurement (Page 14).

4.4Detailed Command Descriptions
The only critical commands for most applications are transmit and
receive frequencies (RX xxx.xxxx, TX xxx.xxxx). However, proper use of
the additional commands allows you to tailor the transceiver for a specific use, or conduct basic diagnostics on the radio. This section provides more detailed information for the user commands previously
listed in Table9 (Page 19).
In many cases, the commands shown here can be used in two ways:
• You can type only the command name to view the currently pro-
grammed data.
• You can set or change the existing data by typing the command,
followed by a space, and then the desired entry. In the list below,
acceptable programming variables, if any, are shown in brackets
following the command name.
ALARM
The ALARM command displays a summary of the radio’s current operating condition. An eight-digit hexadecimal code is presented that can
be decoded as described in “Major Alarms vs. Minor Alarms” on Page
33.
AMASK [0000 0000–FFFF FFFF]
Alarm MaskThe AMASK command displays or sets a mask indicating which events
cause the alarm output signal to be active. Normally, the mask is FFFF
FFFF, meaning that any of the 32 possible events can 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.
05-3305A01, Rev. E 21
Page 30
The eight-digit hexadecimal number used as the command parameter
specifies 0 to 32 events that can trigger the external alarm output (see
Table 10 below for a list of events). The hex value for the mask corresponds to the hex value for the STAT command (Page 31). Each bit that
is a ‘1’ identifies an alarm condition that can trigger the external output.
The AMASK command is used to set or display which events cause the
alarm output signal on pin 25 to be active. The default AMASK is
FFFF FFFF (hexidecimal). Therefore, all major and minor alarms provide a logic high on pin 25. The first four hexidecimal values represent
major alarms that provide a logic high on pin 25, and the next four hexidecimal values represent minor alarms. Converting the hexidecimal
value to binary shows which bits are set in the AMASK. For example:
AMASK (default) = FFFF FFFF (hex)
=1111 1111 1111 1111 1111 1111 1111 1111 (binary)
Each bit represents a different major or minor alarm. The most significant 16 bits represent specific major alarms and the least significant 16
bits represent specific minor alarms. All major and minor alarms are set
as the default AMASK. Use the AMASK command to reset any or all of
these bits if alarm outputs for specific alarms are not desired. Table10
provides a list of event codes.
To disable the alarm signal for a specific alarm, reset the bit associated
to the specific alarm and convert back to hexidecimal.
ASENSE [HI/LO]
Alarm SenseThe 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.
05-3305A01, Rev. E 23
Page 32
BAUD [xxxxx abc]
Data Interface Port
Baud Rate
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 set to one of the following speeds:
1200, 2400, 4800, 9600, or 19200.
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).
NOTE: 7N1, 8O2, and 8E2 are invalid communication settings and are
not supported by the transceiver.
BUFF [ON, OFF] [xxx]
RX Data BufferThis command sets or displays the received data handling mode of the
radio. The command parameter is either ON or OFF. The default is ON.
This command affects the timing of how received RF data is sent out
from the DATA INTERFACE connector. Outgoing (transmitted) data is not
affected by this command.
If data buffering is OFF, the radio operates with the lowest possible
average latency. Data bytes are thus sent out the DATA 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 might be
introduced 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 MODBUS™ that do not allow gaps in their data transmission.
Seamless Mode (BUFF ON) is intended only for applications where the
transmitter’s baud rate is greater than or equal to the receiver’s baud
rate. Enforcement of this rule is left to the user.
In some rare cases, the default timing parameters for Seamless Mode are
not optimal. In these cases, the user might need to specify an exact delay
time. To set a custom delay time, enter BUFF xxx (xxx is a value between
1 and 255). Entering BUFF xxx resets the default delay time.

Page 33
CKEY [ON–OFF]
Key TX
Continuously
The CKEY command enables or disables the continuously-keyed function of the radio. When CKEY is set to ON, the radio is continuously keyed
and the Timeout Timer is disabled.
CTS [0–255]
Clear-to-Send TimeThe 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 ms.
For DCE operation, the timer specifies how long to wait after the RTS
line goes high, before the radio asserts CTS and the DTE transmits 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 through the
DATA INTERFACE port. A timer value of zero means that data is sent
through the data port without imposing a key-up delay. Other delays
might be present based on selected radio operating commands.
DATAKEY [ON, OFF]
Key on Data ActivityThe 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 transceiver’s 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]
Data Device ModeThe 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 transceiver is assumed to be controlling another
radio. It will still key based on the RTS line, but the CTS line is used as
a keyline 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 TransmitterThis command deactivates the transmitter after it has been keyed with
the KEY command.
DIN [ON/OFF]
Digital InputWhen DIN ON is selected, the “not” PTT line (Pin 16 on the DB-25 con-
nector) is re-defined as a digital input for network-wide diagnostics.
See “User-Programmable Interface Output Functions” on Page39 for
more information. The default is DIN OFF.
To change the diagnostic link, enter DLINK followed by one of the following baud rates: 1200, 2400, 4800, 9600, 19200 (default).
DLINK [ON/OFF/xxxx]
Diagnostic LinkUse this command to configure the local diagnostic link protocol
required for network-wide diagnostics.
DLINK ON enables the diagnostic link. DLINK OFF disables the diagnostic
link.

Modem TX Audio
Pre-Emphasis
To change the diagnostic link, enter DLINK followed by one of the following baud rates: 1200, 2400, 4800, 9600, 19200 (default).
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 “Performing Network-Wide Remote Diagnostics” on Page37.
DUMP
This command displays all the programmed settings. 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.
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
radio’s MODEM is turned off (MODEM NONE). It should match the other
radios in the system. The use of pre- and de-emphasis helps reduce the
detrimental influence of high-frequency audio noise.

Packaged Model
Initialization
The INIT command is used to re-initialize the radio’s operating parameters to the factory defaults. This is 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 command
setting caused the problem, this command allows you to return 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 stay in the previously established setting.
INIT [x710]
This command sets the transceiver for “normal” operation outside the
P-20 chassis by setting the following parameters to the values shown
below:
Use this command to restore these three parameters to the standard
transceiver defaults if it was used in a P20 package.

operation, enter 9600 (WDS x710A) or 19200 (WDS x710C). For analog
operation, enter NONE.
When the MODEM is set to NONE, the analog TX Input and RX Audio out-
puts of the DATA INTERFACE are used to interface with the connected
external modem. These levels must match the audio signal level requirements of the external modem. See “RXLEVEL [–20 to +6]” on Page30
and “TXLEVEL [–20 to +6, AUTO]” on Page 32 for details on setting
these levels.

Use this command to display or program the desired RF forward output
power setting of the radio. The PWR command parameter is specified in
dBm and can range from 20 to 37. The default setting is 37 dBm (5 W).
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 6.7 (Page 43).
RSSI
Received Signal
Strength Indicator
This command continuously displays the radio’s Received Signal
Strength Indication (RSSI) in dBm units, until you press the key.
ENTER
You can read incoming signal strengths from –50 dBm to –120 dBm.
NOTE: The RSSI samples the incoming signal for 1 to 2 sec before
providing an average reading to your computer terminal or
HHT.
RTU [ON/OFF/0-80]
RTU SimulatorThis command enables or disables the radio’s internal RTU simulator,
which runs with proprietary polling programs (poll.exe and
rsim.exe). The internal RTU simulator is available whenever diagnostics is enabled in a radio. This command also sets the RTU address to
which the radio will respond.
Use the internal RTU 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.
Use the RTU simulator in a polled environment for testing purposes. See
Publication 05-3467A01
for more information.
RX [xxx.xxxx]
Receive FrequencyThis command selects or displays the radio’s receive frequency in MHz.
The frequency step size is 6.25 kHz. Some models might be set to 5 kHz
steps to match the frequencies of some band plans.
If the customer frequency is not programmed at the factory, a default
frequency is programmed in the radio near the center of the frequency
band.
NOTE: A large change in receive frequency (more than 5 MHz)
05-3305A01, Rev. E 29
requires adjustment of the receiver helical filters for maximum
performance and RSSI. See Section6.2, Helical Filter Adjust-
ment (Page 36) for details.

the last four digits of the serial number.
5.0TROUBLESHOOTING
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 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 internal self-resetting fuse (4A). Remove primary power to reset.
• Secure connections (RF, data and power)
• An efficient and properly aligned antenna system with a good
received signal strength of at least –90 dBm (it is possible for a
system to operate with weaker signals, but reliability will be
degraded).
• Proper programming of the transceiver’s operating parameters
(see Section4.0, TRANSCEIVER PROGRAMMING on Page 15).
• The correct interface between the transceiver and the connected
data equipment (correct cable wiring, proper data format, timing,
and so on).
5.1LED Indicators
The LED status indicators are an important troubleshooting tool and
should be checked whenever a problem is suspected. Table7 on Page14
describes the function of each status LED.
32 05-3305A01, Rev. E
Page 41
5.2Event Codes
When an alarm condition exists, the transceiver creates a code that can
be read on an HHT connected to the DIAG port. These codes can help
resolve many system difficulties. Refer to Table11 (Page 34) for a definition of the event codes.
Checking for Alarms—STAT command
To check for alarms, enter STAT on the HHT. If no alarms exist, the message NO ALARMS PRESENT appears at the top of the display (Figure11).

Major Alarms vs. Minor Alarms
Major Alarms—report serious conditions that generally indicate a hard-
ware failure, or other abnormal condition that prevents (or seriously
hampers) further operation of the transceiver. Major alarms generally
indicate the need for factory repair. Contact us for further assistance.
Minor Alarms—report conditions that, under most circumstances, do
not prevent transceiver operation. This includes out-of-tolerance conditions, baud rate mismatches, and so on. The cause of these alarms should
be investigated and corrected to prevent system failure.

Figure 13. Network-Wide Remote Diagnostics Setup
If a PC is connected to any radio in the network, you can perform intrusive polling (polling that briefly interrupts payload data transmission).
To perform diagnostics without interrupting payload data transmission,
connect the PC to a radio defined as the “root” radio. A radio is defined
as a root radio using the DTYPE ROOT command at the radio.
A complete explanation of remote diagnostics can be found in
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 configure 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.
38 05-3305A01, Rev. E
Page 47
4.Use the DLINK ON and DLINK [baud rate] commands to configure the
(TO COMPUTER)
diagnostic link protocol on the RJ-11 port of each node radio.
5.Connect same-site radios using a null-modem cable at the radios’
diagnostic ports.
6.Connect a PC with InSite software installed to the root
radio, or to one of the nodes, at the radio’s DIAG port (this PC can
also be the PC used to collect payload data, as shown in Figure13).
To connect a PC to the radio’s DIAG port, an RJ-11-to-DB-9 adapter
( P/N 03-3246A01) is required. If desired, an adapter cable can
be made using the information shown in Figure14.

6.4User-Programmable Interface Output
Functions
You can manually activate two pins of the DATA INTERFACE using
MDS’ InSite NMS software. These two outputs (#1–Pin 22 and
#2–Pin 15) can be connected to compatible user-provided data devices.
The pins provide either a logic high or low depending on the last command from the USER I/O SETTINGS in the Network Wide Radio Configuration
screen of InSite. In this InSite window, clicking the SET button sets the
output to high, and clicking on CLEAR sets the output to low. Figure15
shows the software controls.
One pin on the DATA INTERFACE can be configured as a digital
input. If DIN ON is selected, Pin 16 becomes a digital input. The input is
set when 5 V is applied, and clear when grounded. The same physical
input can be queried as the analog input value on other InSite screens.

These output-only pins are designed for low switching rates and do not
pass high-speed data, nor are they suitable for latency-sensitive remote
controls. An example of this function is to reset the connected remote
RTU or turn on a security device at the associated transceiver’s location.
Windows-based Radio Configuration software is available ( P/N
03-3156A01) for upgrading the internal radio software when new features become available from us. Contact us for ordering
information, or download new radio software from www.gemds.com.
To connect a PC to the radio’s DIAG port, an RJ-11 to DB-9 adapter
( P/N 03-3246A01) is required. If desired, an adapter cable can be
made using the information shown in Figure14.
Using the Radio Configuration software, select RADIO SOFTWARE
UPGRADE under the SYSTEM menu. Follow the prompts and online
instructions to determine how to proceed.

Page 49
Software upgrades are distributed as ASCII files with an “.S28” extension. These files use the Motorola S-record format. When the download
is activated, the radio’s PWR LED flashes rapidly to confirm that a
download is in process. The download takes approximately 2 min.
NOTE: If a download fails, the radio is left unprogrammed and inop-
erative. This is indicated by the PWR LED flashing slowly (1
sec on/1 sec off). This condition is only likely if there is a
power failure to the computer or radio during the downloading
process. The download can be attempted again when the fault
is corrected.
6.6External Orderwire Module
During installation or troubleshooting activities, it is desirable to communicate by voice between personnel at the Master Station and the
Remote Station sites to coordinate their activities. An optional external
orderwire module from (P
can be inserted between the radio’s DATA INTERFACE and the user’s
data communication device.
HANDSET JACK
/N 12-1297A01) is available that
ײª·-·¾´» °´¿½» ¸±´¼»®
TO RADIO DATA DEVICE
Installation
Install the Orderwire (O/W) Module between the radio transceiver’s
DATA INTERFACE connector and the connected device. A handset
should also be connected to the associated Master Station’s orderwire
jack.
The payload data exchanges pass through the Orderwire Module uninterrupted until the Orderwire Module is in use. The module has a
voice-operated switch (VOX) that keys the connected transceiver whenever audio is picked up by a handset plugged into the RJ-11 phone jack.
Any standard telephone handset can be used, or a rugged handset (P/N

12-1307A01 without PTT; 12-1307A01 with PTT) can be purchased
from us. Handsets must
have carbon microphone elements
installed. Dynamic microphones do not work with the module. Handsets
with a push-to-talk (PTT) button are supported and recommended, as
background noise can activate the VOX circuit and interrupt the payload
data.
Operation
To operate the orderwire, activate the handset (PTT or VOX). This keys
the transmitter and passes the audio over the network to the handset of
the Master Station. Only one person can speak at a time (simplex). In
noisy locations, it might be necessary to cover the handset mouthpiece
to prevent accidental keying of the transmitter.
NOTE: When the transmitter is keyed by the orderwire operation,
normal payload data is interrupted.
Be sure to disconnect the module or handset to restore normal
data communications.

6.7dBm-Watts-Volts Conversion Chart
Table13 is provided as a convenience for determining the equivalent
wattage or voltage of an RF power expressed in dBm.
Table 13. dBm-Watts-Volts Conversion—for 50 Ohm Systems
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 transceiver.
Active Messaging—This 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—A 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—The 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—See BPS.
BPS—Bits-per-second. A measure of the information transfer rate of
digital data across a communication channel.
Byte—A 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 Equipment—See DCE.
Data Communications Equipment—See DCE.
Data Terminal Equipment—See DTE.
dBi—Decibels referenced to an “ideal” isotropic radiator in free space.
Frequently used to express antenna gain.
dBm—Decibels referenced to one milliwatt. An absolute unit used to
measure signal power, as in transmitter power output, or received signal
strength.
DCE—Data Circuit-terminating Equipment (or Data Communications
Equipment). In data communications terminology, this is the “modem”
side of a computer-to-modem connection. The 1710/2710/ 4710/9710 is a
DCE device.
Digital Signal Processing—See DSP.
44 05-3305A01, Rev. E
Page 53
DSP—Digital Signal Processing. In the1710/2710/4710/9710 transceiver,
the DSP circuitry is responsible for the most critical real-time tasks; primarily modulation, demodulation, and servicing of the data port.
DTE—Data Terminal Equipment. A device that provides data in the
form of digital signals at its output. Connects to the DCE device.
Equalization—The process of reducing the effects of amplitude, fre-
quency or phase distortion with compensating networks.
Fade Margin—The 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—A segment of data that adheres to a specific data protocol and
contains definite start and end points. It provides a method of synchronizing transmissions.
Hardware Flow Control—A 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 transmission until CTS again returns to the high state.
Host Computer—The computer installed at the master station site,
which controls the collection of data from one or more remote sites.
Intrusive Diagnostics—A 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.
Latency—The delay (usually expressed in milliseconds) between when
data is applied to TXD (Pin 2) at one radio, until it appears at RXD
(Pin3) at the other radio.
MAS—Multiple Address System. A radio system where a central
master station communicates with several remote stations for the purpose of gathering telemetry data.
Master (Station)—Radio which is connected to the host computer. It is
the point at which polling enters the network.
MCU—Microcontroller Unit. This is the processor responsible for con-
trolling system start-up, synthesizer loading, and key-up control.
Network-Wide Diagnostics—An advanced method of controlling and
interrogating our radios in a radio network.
Non-intrusive diagnostics—See Passive messaging.
Passive messaging—This 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—This is the application’s 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—A radio communications network or
system designed with a central control station that exchanges data with
a number of remote locations equipped with terminal equipment.
Poll—A request for data issued from the host computer (or master PLC)
to a remote radio.
PLC—Programmable 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 Controller—See PLC.
Remote (Station)—A radio in a network that communicates with an
associated master station.
Remote Terminal Unit—See RTU.
Redundant Operation—A station arrangement where two transceivers
and two power supplies are available for operation, with automatic switchover in case of a failure.
RTU—Remote 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.
SCADA—Supervisory Control And Data Acquisition. An overall term
for the functions commonly provided through an MAS radio system.
Standing Wave Ratio—See SWR.
Supervisory Control And Data Acquisition—See SCADA.
SWR—Standing 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).
