4.6 Exciter to Transmitter Interface
Exciter interface cables included in STXe60 kits, 949-4144 or 949-4150, are built using
solder pot D-subminiature connectors that can be accessed by opening the shell. These can
be modified to suit the requirements of the transmission system.
The 919-4001 interface adapter board is required to adapt machine interfaces of select
transmitters, such as C- and T-series transmitters, that output active high control logic. Note
that STXe60 output signals pass through unchanged. Systems with active low/ground
control logic can skip this section. Follow the remaining steps in this section to mount this
adapter to a P-rail in the back of a rack and make the required cable connections.
