MSA 665 linear Encoder

Hi all
I 'm fresh meat here in this forum and I would like to ask for some help with a linear Encoder that I recently picked up, its a MSA655 linear Encoder without a Plug connection on the cable, if anyone is able to give details for the Wiring diagram +5V, Gnd, ChA, ChB.

There is a red & Black wire perhaps thats +5V & Gnd if that can be confirmed I'm sure I could figure the rest out using the Scope.
btw I have had no replies from RSF Elektronik .

PN Code: 82277804
No: 081-0308430110
Grating: 0.04mm
MSA: 665
Spec: 5F
Zero ref Pulse: 7

TIA
Regards
Thomas
