Internal pin layout for Analog in/out IF-AN24 board

[Ittol]

Hello,
I purchased an IF-AN24 board on Ebay, but the 50pin IDC flat ribbon cable is missing.
Those cables and connectors are easy to find , but I need the wiring diagram, since there must be 2 50 pin IDC connectors at one end ( one for the input, and one for the output) and one connector at the other end to the mother board.
Maybe it can be found on the MX2424 service manual ?
Thanks for your help

Looking at my cables they are pin 1 to pin 1 2 to2 and so on, same with the loop part of the cable for Input and output.

Hope that makes since

Thank you Warren,
If I understand, both input and output are on the same wire?
