I've been thinking of working on a controller design that can talk back to the computer. I use addressable Renards (all boards receive the same signal) have the RS485 chip that can receive and transmit, but only the receive side is being used. I've been thinking that if the controller could talk back it could help identify comm issues, and potentially other issues such as power used, bad zero cross etc while they are in the field. I also realize that with comm speeds required to run a show, this would be a "mode" the controller would be put into and not used during the show times, but only during the testing or nightly at startup.
I'm just in the brain storming part of this activity, and thought maybe this excellet group could provide some input on what would be nice/fun to report back. Some/most may not be possible, but it's ok to dream isn't it?
Here is what I've come up with so far:
1. quality of packet received, (checksum?)
2. DC voltage on the board (volts)
3. current required to operate the SSRs (amps)
3. if AC power is to the SSR's (yes/no)
4. zero cross (Hz)
What else do you think I could look at?
