8. OPERATION
8.1 INTRODUCTION
This Section describes the normal operation of the SSPB Block Up-Converter. The design of this
equipment allows for minimal operator intervention and maintenance.
The SSPB or the system may be monitored and controlled via the RS-232 or the RS-485 serial
interfaces, or via the Relay interface. The Relay interface provides for the user an alarm
indication and remote RF mute capability of the designated SSPB unit. The RS-232 and the RS-
485 serial interfaces provide access to the SSPB functions, including the monitoring of key
operating parameters and shutdown (mute) command.
8.2 SAFETY CONSIDERATIONS
WARNING:
Prolonged operation without a load at the output may cause severe bodily
harm, loss of sight, even death. Do not operate any transceiver if the RF output connector
is not connected to a load.
Please note that an SSPB Block Up-Converter 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
was
performed successfully.
2. Switch ON the main power source.
3. Wait for the software to boot into PC.
4. Using the RS-232 interface set up the serial communication linkage between a unit and the
user’s computer terminal. Press
t2
(command to switch to PC Terminal) in Term95 or
HyperTerminal communications program.
CAUTION:
The unit will always start in RF ON state. In order to MUTE the unit, the
communication link through RS-232 serial interface should be established, using Term95 or
HyperTerminal communications program. Use
t2
command to switch for PC communications
and then use
txm
command to mute the unit.
5. Ensure that the L-Band input signal is being applied to the SSPB unit.
