Thanks for your input. I did that last night. I will keep my fingers crossed.Are you using the network interface?
Test by disconnecting the Ethernet interface(s) and doing a power off (battery and transformer) rebooting and watching to see if it happens again in a day or two.
Thanks. I will try that. I even changed keypad address for grins and giggles.After doing what Pete suggests, you may want to disconnect the keypads, one at a time. It can be something on the keypad bus.
