After reading the preceding thread, I thought I would pose a question to the list:
Does anyone know of a rotator interface for controlling selsyn motors? I have a dish that uses them for az and el drives. They seem to take +/-10 volts to position the dish. Dish position is determined from digital angle encoders (gray code). Unfortunately when I obtained the dish, I did not get the pointing software. It is complete with computer controller that talks via RS-232 with a computer running the tracking program. The company that built the dish is long out of business so no luck on getting schematics or software. These were custom built (only ten made).
