Crystal Vision
Installation
2.4 Connector pinout
Remote control / GPI connections
Each module slot has six connections that are brought out to one or more of the two
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.

The total current available from the 5.3V DC outputs is limited to approximately
1.5 Amps.
To maintain EMC compliance only good quality screened cable assemblies
should be used.
