I know there have been a lot of posts about wiring the AD2USB, but all the instructions say something like "use the standard 4-wire connection to the panel, just like a keypad" - or they talk about pinouts (4, 5, 6 and 7).
I'm not an expert in Ademco security panels, but I do have access near my PC to the 4 keypad wires. However, they are not labeled DI, DO, 12V and ground (and I can't see the pins they are connected to) - instead, the wires are four different colors (red, black, green and I think yellow, have to check). I can't easily follow the wires back to the panel itself, which is three floors above where I have access to the wires.
Does anyone know which color wires correspond to DO/DI/12V/Ground?
Thanks in advance for your help.
