[amsat-bb] Yaesu rotator connections

I have a Yaesu G-1000-DXA rotator and controller for azimuth. After I got into working satellites I purchased a used Yaesu G-5500 elevation rotator and the dual Az/El controller. (Thanks AA5PK it has been working great!)

I would like to hook the G-1000-DXA cable to the G-5500 controller but can't figure out how the pins correspond. Both are 6 wire cables. I found a better schematic for the G-5500 on the Yaesu site than was in my manual - it appears pins 4-5-6 have to do with power for the G-5500.

On the G-1000-DXA pins 4-5 are power, so in a wild guess I tried hooking 1-1, 2-2, 3-3, 4-4, 5-5, 6-6, but nothing happens.

Does anyone know how I need to hook this up?

Thanks
