Help needed for a Contegra console

[Ciphernet]

Hi all,

I have just purchased an old Comtegra console type L1925A but I need a pin-out for the DIN power connection at the back.

I have been told that these units can use MDC1200 signalling depending on the options selected but I am not sure if this console have these functions available. I opened the unit and checked the EPROM. It has "TGL CBAS.1M" printed on a label. I guess that it tells the firmware version installed but I have no clue what options the firmware contains.

Also are the impedance used for the balanced repeater connection 600 ohms?

How about it?? Can anybody on the board help me with these few questions...?? I am much more into Astro handhelds than base station equipment.
