2.14 Parallel Remote Control Connections
External Parallel remote control units can interface at the External I/O Board in the
rear of the cabinet. J13 through J17 are for remote Control, Status and Analogue
readings. The connectors are organised as follows:
•
J13 and J14 - Remote Transmitter Control Functions
•
J15 and J16 - Remote Status Outputs
•
J17 - Remote Analogue Metering Outputs
NOTE:
The forward slash ( / ) in front of a signal name means active low. The signal
/INPUT 1 for example is activated by momentarily bringing that input low.
Signal names without the forward slash are considered active high. This con-
vention is used throughout the schematics.
