need pinouts for qube 3 - unit needs 5, 12, and -12v power

I am unable to identify the supply lines.. I do know the grounds.

Known: the unit needs +5, +12, and -12 volts

unknown: which terminals on the 8 pin din connector is the 12, 5, and

USE: this number layout

I know pins 7,5,4 are connected to ground (chassis)

if someone here with a qube 3 could measure the pins it would be
greatly appreciated.

SEARCHED the web for this NO INFO anywhere to be found.

why couldnt the manufacturer supplied this fundamental info in their
user manuals .

post results here or at
