3.4.6 Interface M&C Connector (J6)
The interface M&C connector (J6) is a 26-pin, MS style, female connector. It provides
the system M&C interface with EIA-485 or EIA-422 control of the redundant
KST-2000A/B, provides diode OR'd +12V power for a KP-10, and routes uplink and
downlink fault relay contacts from each KST-2000A/B to the remote M&C system. Refer
to Table 3-6 for connector pinout.
