Installation
2.4 Connector pinout
Remote control / GPI connections
Each frame slot has six connections that are brought out to one or more of the four high-
density D-Type connectors on the rear of the frame labelled RMT 1 and RMT 2. These
connections are referred to as lines 'a' to 'f'. The functions assigned to them are dependent on
the module inserted in each slot, but a typical use is as a GPI line. Refer to the documentation
supplied with each Crystal Vision module to determine the actual functions assigned.
RMT 1 and RMT 2 connections (26-way high density D-Type socket and plug):
