DIU3000 data output question

Postby thebopps » Wed Nov 20, 2013 12:29 pm

Does the DIU3000 output data (unit id, talk group info, etc.) out of the COMPUTER port on the front of the device?

If it does then it's not documented in anything I've seen both that's not to say it can't.

The DIU does output the talkgroup, unit ID, and emergency status via the "Centracom Signalling Link", which is a subset of pins on one of the DB-25's on the back. It's 9600 baud asynchronous data, but the protocol/format is proprietary. If I remember right, it periodically sends a byte or two, looking for a response from the Centracom console. If it doesn't get that response, you won't see any of that talkgroup or unit ID data.

I've heard if you send the same byte or bytes back to it, it will start to send more stuff... But I've never actually tried it.

The newer DIU's came with a small booklet that covered the "Centracom Signalling Link" connections and operation.

I think the DIU does send an error message out the COMPUTER port on the front when it receives a transmission encrypted with a key that it doesn't have, but that's about it from what I've seen.
