7. OPERATION

This Section describes the normal operation of the SSPB in a stand-alone configuration. The

design of this equipment allows for minimal operator intervention and maintenance.

The SSPB may be monitored and controlled via the RS-232 or RS-485 Serial Interfaces, Discrete

Interface or from the front panel controls and display. The Discrete Interface provides for the user

an alarm indication and remote RF mute capability. The RS-232 and the RS-485 Serial Interfaces

and the front panel controls and display provide access to the unit's functions including system

monitoring of key operating parameters, control of gain, frequency and shutdown (mute).

A software communication program is provided with the SSPB allowing full access to the unit's

functions. For front panel operation refer to Figure 6 at page 33.

WARNING:

Prolonged operation without a load at the output may cause severe bodily

harm, loss of sight and even death. Do not operate the SSPB if the RF output connector is not

connected to a proper load.

Please note that an SSPB failure due to the above condition will be attributed to abuse or neglect

and will not be covered by the standard warranty.

Perform the following operating procedure:

1. Verify that the 'Pre-Power and System Checkout' procedure as described in Section 6 at page

29 was performed successfully.

2. Switch ON the main power source.

3. Wait for the software to boot into a PC.

4. Turn on the front panel power switch. The Alarm LED must be unlit.

5. 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 7.6 at page 34. Press t2

<ENTER> (command to switch to PC Terminal) in Term95 or HyperTerminal

communications program. After establishing communication, use the command txu <ENTER>

(transmission un-mute) to un-mute the unit. Ensure that the L-Band input signal is being applied

to the SSPB.
