[BC] Query about modules...

[Tom]

HELP!

Big query for the brain trust...

I have acquired a couple of 8-channel auxiliary input modules from 
some sort of German (I believe) console.  Poser:

said modules use 2 - 25pin D connectors for in/out/power

The circuit board says "KM-E-8P" and the number 840117.

The modules also carry what appears to be a model number on a sticker - E610E

Also, same sticker seems to have a "serial number" - Nr 204 on one, 
and Nr 210 on the other.

Manufacturer appears to be TBG.  units are clean, and by appearances 
they should be able to be powered up and / or interfaced - IF i only 
knew a) which pins to power at what voltage(s) and polarities, and b) 
which pins carry which signals.

Anyone ever hear of these dudes?  Google-fu is most unhelpful with 
these babies...

Any and all info appreciated....
