Fischer connectors for Cello equipment

Can someone tell me (a) the model number of the Fischer connectors used in Cello equipment, and (b) which pins are +/- and ground? Thanks.
I'm not familiar with the particular Fischer connector used on the Cello but you can go to and cruise through their online catalog. If you need more help, call them at (800) 551-0121 and ask to speak to Tomika Cameron, she's very helpful. You might also want to call Cello at 203-865-1237

I've bought a lot of Camac/RCA adaptors and Camac shorting plugs for my Levinson gear directly from them.

Good luck!
