older G-11 mount with encoders for hand slewing on gemini 1

A couple of years ago I bought a used G-11 and it seems to have encoders for hand slewing the telescope without needing to recalibrate the mount but it was missing the cable needed to connect the encoders to the gemini 1 computer.  Losmandy did not seem to know what I was talking about as well as I started a thread here with no response so I am trying again.  Anybody know anything about this?

The Gemini 1 does have an encoder port.....and there is information in the losmandy gemini 1 on connecting the encoders. If you scroll almost all the way to the bottom of the manual you will find some info including pin configurations etc......page 127.

Per the manual the Y cables for most popular DSC's will work for this.....

Thanks Greg.  I will try Losmandy again to see if they can supply the "Y" cable.

You can probably get a compatible Y cable here..... http://www.skyeng.com/  Both my GM-100 and GM-200 losmandy mounts have losmandy encoders and work fine with my Sky Commander and its Y cable....
