Swapping BME #0 RS-232 / RS-422 Ports

Swapping BME #0 RS-232/RS-422 ports (not required on BME #1 - BME #5) involves moving a ribbon cable from one Main Control card connector to another.

Ribbon Cable Connectors

The ribbon cables used in the Matrix 3200/6400
Video Switcher use a self-latching style receptacle.
Figure 5-4.A shows how it operates.
1. Press each of the two tabs outward, this unlocks
the receptacle and ejects the ribbon cable
connector part way. Pull evenly on the ribbon
cable connector to remove it.
2. When reconnecting the cable, first align the pins
in the receptacle with the holes in the connector
and press evenly into the receptacle until the
receptacle tabs lock the connector in place.	Figure 5-4.A
