That particular cable was designed by one of our Partners and I do not have access to the pinout.

Microscan does offer a backward compatible cable to make the new QX-870's M-12 connectors into a single 25 pin DB sub like the one that would have been found on the MS-860.

The part number is 61-000172-01 QX Cordset, M12 12-pin plug and M12 12-pin socket to DB25 socket, 2 m.

It is referred to in the Transition Guide and on the website (page 9) .
Here is the transition guide link: Transition Guide
Pinout of cable is also on website: Pinout
(Both are in the Tech Support Self Help.)

Pinout of any Microscan cable can be sent upon request by emailing Helpdesk@microscan.com.

Having the pinout for this cable on the website would be helpful.
