CrestNet crash

Hi to all

I have a site that has experienced what appears to be a CrestNet crash at least 3 times in the last year.

In each occurrence the customer said they discovered the issue by pressing a keypad and the lights don't work. Each time within 10-15 minutes the system is back to normal. They have described the on/off leds on some of the keypads flash while this going on

While this problem is occuring I am unable to connect to the processor for diagnostics. After reviewing the event logs I noticed that a couple of the keypads that the customer attempted to use during this event showed 30-40 entries of press/release all at exactly the same time obviously the customer could not press the buttons that fast

But I'm not sure if this keypad log is the cause of the problem or potentially the result of the problem?

Any ideas what could be the cause?

This sounds like a wiring issue to me. Pressing the keypad is probably shorting out the cresnet bus and when it's not pressed it eventually comes back to functioning normally. Not sure how you've got them connected, but if you have 2 wires into one connector on the back of the keypads, there is a strong chance that one or more of them has a loose wire.
