1. To use the Relay interface, construct the interconnecting cable using the mating connector
provided in the shipping kit (see TABLE 2 at page 21). Refer to TABLE 3 at page 22 for
the correct pin assignment.
2. To use the RS-232 serial interface, construct an interconnecting cable with a proper mating
connector as given by TABLE 2 at page 21. Refer to TABLE 4 at page 23 for the correct
pin assignment.
3. To use the RS-485 serial interface, construct an interconnecting cable with a proper mating
connector as given by TABLE 2 at page 21. Refer to TABLE 5 at page 24 for the correct
pin assignment.
4. Construct an AC (or DC) power cable with a proper mating connector as given by TABLE 2
at page 21. For the correct pin assignment, refer to TABLE 8 at page 28.

ONSIDERATIONS
The AWMT contains a forced air cooling system, which prevents the internal components from
overheating. The cooling subsystem consists of a single fan operating at a variable speed to
effectively distribute and remove the air from within the AWMT unit.
Prior to installing the AWMT, verify that:
1. Environmental conditions listed in TABLE 6 below will be met.
TABLE 6 : ENVIRONMENTAL CONDITIONS
Temperature:
Non-operating (continuous exposure)
Operating (ambient) - 50° C to + 85° C
- 30° C to + 55° C
Relative Humidity: 100% max., condensing, up to 2”/hr rain
Altitude: 10,000’ AMSL, derated 2° C / 1,000’ from AMSL
2. A minimum clearance of 30-cm (12 inches) is necessary in front of the air intake and exhaust
openings on the AWMT mounting-frame.
3. The fan intake grill and the exhaust openings of the AWMT are free of obstructing debris.
CAUTION! Obstructing objects and/or debris may reduce the efficiency of the cooling system
and significantly impact the transceiver longevity.
