cDAQ-9189 chassis documentation

I am using a CompactDAQ system for some robotics testing, and I need to connect a custom module the cDAQ-9189 chassis. Is there documentation for the pinout of the DB 15 connector used on the CompactDAQ chassis backplane? I have searched the user manual for that information, and spent a good deal of time on NI's website, but I cannot find this information. Does anyone have this information?


Thanks in advance.

From what I found and the links below, custom cDAQ modules are rare.  But the CompactRIO has quite a few 3rd party modules and a development kit.

This is the only 3rd party module I found for cDAQ
