JMI MiniMax Pinout Help

I recently purchased a JMI MiniMax DSC system off AstroMart and am about to install it on my Dob. I am missing one 5 pin encoder plug to RJ11 female jack adapter. I was going to use the other one as a guide to make a couple new ones but after looking it over it seems to me that channels A and B are backwards. Each ALT and AZ male RJ11 jack that comes from the computer unit has four (4) colored wires in it (yellow, green, red, and black). Can anyone tell me which colour is associated with which pin on the encoder. I have a schematic of the US Digital encoders and the pin values.

Thanks in advance,

Dave.

Thats correct, they are reversed. We need to know which encoder you are working with so the we can get it right the first time. Anyway, if one of them is intact, the other is the exact opposite. Black, skip, red, green, yellow. One of your encoders runs with a negative sign in the setup routine.
