Hardware
HPAC-100/125/150/200/250-RM units
Two HPAC-100/125/150/200/250-RM units are used for a 1:1 redundant configuration.
They communicate with each other through the interface cable passing system control-
ler information, serial information, and fault information. The units distinguish them-
selves by their factory set local addresses.
Power Supply
Each amplifier contains a +28V power supply to supply power to the waveguide/coaxial
switch.
RF Switch
The HPAC-100/125/150/200/250-RM redundant system controls a -28V waveguide/
coaxial switch using the 6-pin rear panel connector. The switches are controlled by
ap28V to the common of the switch and pulsing either position to ground.
The system then verifies the position of each switch.
Switch Connector
The 6-pin circular connector (MS3112E10-6S) on the rear panel is used to interface
with the switch. Table B-1 lists each pin function.
