Remote Control Mode, Computer Control
Refer to Chapter 2 for connection details and 0103123300 (CIF
protocol) for communication and command details. Also refer to
Appendix B for operation with CPI supplied Setup & Remote
Control Software (remote.exe).
In the LOCAL mode, turn the amplifier ON and set it for the
REMOTE control mode. Install the supplied remote.exe program or
a user-supplied amplifier control program in the computer to be
used for normal operations. Using this program, setup the
operating parameters and operate the amplifier.

Shutdown
5.4.1
Normal Shutdown
If no transmission is planned for an hour or two, the amplifier AC
power should be switched off to conserve electricity and prolong
the life of the TWT (traveling wave tube). Proceed as follows:
a.
b.
c.
5.4.2
Prime Power Interrupts
The amplifier will automatically recover after a prime power
failure. Transient prime power interrupts result in proportional
time delays before the amplifier returns to the pre-interrupt
operational state. (See 5.6.2.) The purpose of the proportional
delay cycle is to re-establish the proper cathode operating
temperature before the high voltage is turned ON.
5-4
Place the amplifier in "STANDBY" mode. Verify that the
STANDBY LED is lit.
Wait approximately 5 minutes to allow the TWT to cool off.
(The fan will still be operating.)
Switch off the applied AC power.
