Hello group,
I've been working to use an astrotac 3000 comparator in an Amateur radio mixed mode repeater system. I got it working OK so far but I would like to be able to extract live info and control from the comparator. In research I found third party products that are used to monitor and control the comparator. Being a cheap Amateur I need info on info that can be read from the RS 232 port on the Scm if possible. CTI products has a device that talks to the synchronous port J 15 I have no Idea how to interface with a synchronous port, Any Info here. Is there info on the available commands that one can talk to the comparator via the rs232 port ?
One critical thing I need is to get a COS signal out of the comparator when a analog signal is voted so I can interface it to a repeater analog controller. The controller is used to do analog linking with other repeaters. One solution is to use a companion Digitac analog voter. But I have no rack space to do that . Any ideas or information out there would be greatly appreciated
Thanks
regards
Larry

Only way I've ever seen to get voting information out of these things is with the CTI Products equipment.

I wouldn't put any DIGITAC comparators in service due to high failure rates as they age (and I speak from experience). Your money is better spent on a JPS SNV12 or SpectraTAC comparator for analog voting.
