Issue
Correlate which output relays go with which resident I/O addresses in the 7780
Environment
7780 Lighting Controller Resident I/O Editor
Cause
Wiring diagrams and software designations need to line up for proper lighting control.
Resolution
On the 7780 the first matrix card controls the bottom eight on each side of the controller giving you your first 16 relays. The bottom front relay on the right side is your first relay. The relay directly behind it is the second relay. This continues up the right side of the controller till you reach the eighth relay, then the numbering jumps to the front bottom left relay and continues with relay number nine. The first relay will be circuit 0000. The second relay will be 0001 and so on. Till you reach 0007. Relay nine will be 0100, ten will be 0101, etc..
