Power Monitoring Connections to J11
In systems with one or more external amplifiers, J11 is used to communicate the output
forward and reflected metering voltages back to the driver. J11 is connected directly to
the external amplifier when there is only one external amplifier and is connected through
the system metering module when multiple external amplifiers are used.
In multiple external amplifier systems there are thermal switches mounted on the output
combiner reject loads. The reject load interlock is connected to thermal switches and is
used to shut down the system if the reject load overheats. In systems with no external
amplifier, the only connection used is the Reject Load Interlock, which must be
connected to Supply Return using a jumper from J11-6 to J11-9.

Remote Connections to J12
The remote connections for the Innovator CX Series system are made to the Remote 15
Pos Female “D” connector Jack J12 located on the rear panel of the drawer.
NOTE: In dual exciter systems, remote connections are made to the rear panels of the
two drivers.
