QUICK START GUIDE
Below are the basic steps for installing the transceiver. Detailed instructions are provided in
“Installation
Steps” on Page 9
of this manual.
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/reception.
2.
Connect the data equipment to the radio’s 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 con
fi
gured as DTE. (By default, the radio is con
fi
gured as DCE.)
3.
Apply DC power to the radio (10.5–16 Vdc @ 2.5 A minimum)
• Observe proper polarity. The red wire is the positive lead; the black is negative.
4.
Set the radio’s basic con
fi
guration with a Hand-Held Terminal (HHT)
• Set the transmit frequency (
TX xxx.xxxxx
).
• Set the receive frequency (
RX xxx.xxxxx
).
• Set/verify the data rate using the
BAUD
command. The default setting is
BAUD 4800 8N1
. (Refer to
“TRANSCEIVER PROGRAMMING” on Page 17
for command details.)
5.
Verify proper operation by observing the LED display
• Refer to
Table 5 on Page 16
for a description of the status LEDs.
• Re
fi
ne directional antenna headings for maximum receive signal strength using the
RSSI
com-
mand.

FACTORY REPAIRS
Component-level repair of radio equipment is
not
recommended in the field. Many compo-
nents are installed using surface mount tech-
nology, which requires specialized training
and equipment for proper servicing. For this
reason, the equipment should be returned to
the factory for any PC board repairs. The
factory is best equipped to diagnose, repair and
align your radio to its proper operating specifi-
cations.
If return of the equipment is necessary, you
will be issued a Service Return Order (SRO)
number. The SRO number will help expedite
the repair so that the equipment can be repaired
and returned to you as quickly as possible.
Please be sure to include the SRO number on
the outside of the shipping box, and on any
correspondence relating to the repair.
No
equipment will be accepted for repair without
an SRO number.
A statement should accompany the radio
describing, in detail, the trouble symptom(s),
and a description of any associated equipment
normally connected to the radio. It is also
important to include the name and telephone
number of a person in your organization who
can be contacted if additional information is
required.
The radio must be properly packed for return
to the factory. The original shipping container
and packaging materials should be used when-
ever possible. All factory returns should be
addressed to:
When repairs have been completed, the equip-
ment will be returned to you by the same ship-
ping method used to send it to the factory.
Please specify if you wish to make different
shipping arrangements. To inquire about an in-
process repair, you may contact our Product
Services Group at: 585-241-5540 (FAX: 585-
242-8400) or vie e-mail at:
