We have recently installed an M2 az/el system, with two of the controllers mentioned above. The controllers are separate units, linked with a single ribbon cable.
The units work OK when given raw commands using hyperterm, but only the last addressed unit seems to send back to hyperterm its info as it moves. Ie send a command to change Az, followed immeadiately by a command to change El, and only the El position appears in hyper term as its changing.
Command the az/el from the front panel of the units works OK, also.
When we try using 'standard' ham satellite software, eg Nova, nothing seems to happen. The rotors just dont budge.
If anyone has any experience in solving this problem, I'd love to hear from them
