What’s the Problem? What it means: How to Resolve:
Modem will not power
up or down The wiring to the modem may not be connected
properly.
•Check the ignition sense
wiring.
•Verify that the diagnostic port
is plugged in correctly.
•Check LED status to see if the
modem is communicating.
NOTE: The Status LED remains red for up to 3 minutes after power is applied to the
iR1200 or immediately after the Reset button is pressed
The following important information will allow you to safely operate the iR1200 and
iR1200 GPS-Enabled modems.
Safe Operating Guidelines
Your modem contains a transmitter and receiver. When it is ON, it receives and transmits
radio frequency (RF) energy. This product is authorized by FCC Rule Part 47CFR 2.989 which
states that it should be used in such a way that it maintains a distance of at least 8 inches (20
cms) between the radio’s antenna and the human body.
Medical and Personal Electronic Devices
Most electronic equipment is protected from RF energy. However, certain equipment may not
be shielded against RF signals being emitted from your modem.
Pacemakers
Operators should not use the modem if individuals with pacemakers are within 6 inches (0.15
meters) of the antenna.
Hearing Aids
The modem may interfere with hearing aid devices. Individuals who experience such
interference should consult the hearing aid manufacturer to discuss alternative solutions.
Other Medical Devices
Individuals who have other medical devices not specifically mentioned in this guide and may
want to consult their physician or device manufacturer to determine if it is adequately
protected from external RF energy.
Interference with Other Electronic Devices
RF energy may affect improperly installed or inadequately protected electronic operating and
entertainment systems in motor vehicles. Check with the manufacturer or representative to
determine if these systems are adequately shielded from external RF energy.
Introduction
The iR1200 modem is designed to work specifically within the iDEN
 network.
Once installed and configured, it provides you with wireless data communications.
This quick reference guide provides important information for operating your
modem.
Getting Started
The modem is designed to power up or turn ON when an ignition signal is sensed.
Power Up from Vehicle:
1. Turn ON your iR1200 modem by simply starting your vehicle.
2. The modem automatically turns on and connects to the Nextel network
(this process may take up to 3 minutes).
3. Turn on your mobile device (e.g., laptop, Mobile Data Terminal (MDT),
etc).
4. Use your mobile device to receive or send information.
Power Up from Building or Desktop:
1. Insert the ignition bypass plug into the IGNITION connector located on
the back panel of the modem.
2. Turn ON your iR1200 modem by plugging the power connector into a
12-volt DC power supply.
3. Turn on your mobile device (i.e. laptop, MDT, etc.).
4. Use your mobile device to send and receive information.
LED Indicators and Statuses
LEDs on the front panel of the modem indicate whether it is operating
appropriately. The following table summarizes what each LED indicates.
LED (signal indicators)
displays the modem’s
serial interface status.
Status LED
displays the
modem’s
iDEN network
status.
Diagnostic Connector
used to receive modem
diagnostic information.
Pressing the reset button
on the front panel of the
modem will cause the
modem to recycle power,
equivalent to re-
establishing the connection
to the network.
LED (signal indicators)
displays the modem’s
serial interface status.
Status LED
displays the
modem’s
iDEN network
status.
Diagnostic Connector
used to receive modem
diagnostic information.

Quick Reference Guide
The following table will help you determine if the modem is communicating
appropriately.
Signal Color Indication
Tx Blinking
Green Modem is transmitting data to the computer data terminal.
Rx Blinking
Green Modem is receiving data from the computer. Modem is receiving data from the computer.
RTS Green
(Off) Request To Send from computer is asserted (not asserted).
CTS Green
(Off) Clear To Send from modem is asserted (not asserted).
DTR Green
(Off) Data terminal equipment is ready (not ready).
DSR Green
(Off) Modem is ready (not ready).
STATUS Solid
Red The modem is searching for signal within the Nextel network. If the modem status changes from blinking green back to solid red,
the signal has been lost and the modem is attempting to re-
acquire.
NOTE: If after a period of several minutes, the status does
not return to green, you may be out of range. The
modem will attempt to re-acquire automatically
when you are back in range.
The STATUS indicators are different depending on the type of mode the modem is
operating in. The following table lists the STATUS indicators for the Packet Data and
Circuit Switched Data modes.
Packet Data:
STATUS Blinking
Green In-range (modem is connected to the Nextel network) but idle (but not passing data).
STATUS Blinking
Green The modem is in use – Nextel network communication is active and is passing data.
Circuit Switched Data:
STATUS Blinking
Green In-range (modem is connected to the Nextel Network) but idle (but not passing data).
STATUS Solid
Green The modem is in use – Nextel network communication is active and is passing data.
Common Problems
What’s the
Problem?
What it means: How to Resolve:
Nothing happens when
I power up the modem. No power is being supplied to the modem. There are several things that could be wrong. Go through this list and eliminate
all the possible problems:
•Is the ignition on?
•Is the ignition bypass plug inserted
into the IGNITION connector on the
modem (for building installations)?
•Check power supply and make
sure that everything is connected
properly.
•Is the battery voltage at least 12
volts?
•Check the cables and wiring.
The modem has power
but the LED light is not
blinking green.
Check to make sure the antenna is
properly connected.
The modem doesn’t
appear to be
communicating.
This could indicate a
number of things (see
How to Resolve column
to eliminate the
possibilities).
Verify cabling:
•Is data cable plugged into the
diagnostic port?
•Is data cable connected properly to
the mobile device or computer.
•Check the RSSI
•Check coverage - move to another
location to see if coverage is not
affected.
•Verify that your account has been
activated.
GPS does not operate. Either:
- Coverage in the area is
bad
- Antenna may be
improperly installed or
defective.
•Verify that the antenna has direct
line of sight to satellite.
•Move to another area
GPS is slow. It is normal for the GPS
to take up to 5 minutes to
acquire the first reading.
Wait for an appropriate amount of time
for communication to take place. If
attempts take longer than 5 minutes,
contact your system administrator.
