3 MXi AMPLIFIER CONTROLLER
The MXi amplifier control board (Assembly 31C1897) is a single-circuit assembly that provides all of the control
functions required for the MXi series amplifier on a single circuit board. This board can be configured for a number
of different amplifier types, power levels, transmission standards and options.

The board implements status/telemetry for remote monitoring through a rear panel connector that will interface to
a typical remote control systems (such as Moseley or Gentner). An RS232 serial port is also provided to allow
communication with the main controller located inside the main control chassis. The MXi control board has RF
detectors for forward and reflected power and all the circuitry to support AGC/VSWR/Cutback functions.
