8. OPERATION
8.1 INTRODUCTION
This Section describes the normal operation of the AWMT. The design of this equipment allows
for minimal operator intervention and maintenance.
The AWMT may be monitored and controlled via the serial interfaces, or the Relay interface.
The Relay interface provides for the user an alarm indication and remote RF mute capability of
the designated AWMT unit. The RS-232 and the RS-485 serial interfaces provide access to the
AWMT functions, including the monitoring of key operating parameters, gain control (in both
transmission and receive paths), transmission/receive frequency control and shutdown.
8.2 SAFETY CONSIDERATIONS
WARNING! Prolonged operation without a load at the output may cause severe bodily
harm, loss of sight and even death. Do not operate the transceiver if the RF
output connector is not connected to a load.
Please note that an AWMT failure due to the above condition will be attributed to abuse or
neglect and will not be covered by the standard warranty.
8.3 BASIC OPERATING PROCEDURE
Perform the following operating procedure:
1. Verify that the ‘Pre-Power and System Checkout’ procedure as described in Section 7 at
page 29 was performed successfully.
2. Switch ON the main power source.
3. Allow at least ten seconds for the software to boot into the PC.
4. If using either the RS-232 or the RS-485 interface, set up the serial communication linkage
between the AWMT and the user’s computer terminal. See Section 8.5 at page 33. Press t2
(command to switch to PC Terminal) and <ENTER> in Term95 or HyperTerminal
