Trouble with install. My Vista terminals have numbers

[joedavis44]

Hi,

Trying to install an Invisalink 3 into my Vista 20P panel. The instructions say to run four wires into the four terminals on the Vista board labeled Red, BLK, YEL, and GRN. However, my Vista does not have any letters on the terminals. They are just labeled 1-25.

I looked at the schematic on the panel door and I think I figured out that these four colors are for the expansion modules which go into Terminals 4-7. This is the mapping I get from the schematic:
BLK - Term 4
RED - Term 5
GRN - Term 6
YEL - Term 7

I think this is correct, but thought I would check in here to see if any one can confirm I am doing this correctly before I possibly blow the board or the Vista.

Thanks for any help.

Joe
