No Controller Data on my keypad. Help!

[dj2099113]

So I'm having an issue that i've seen discussed on this forum before where the keypads show no controller data on them. For starters, im running an OmniPro II with 2 keypads and one touchscreen keypad connected. 2 Backup batteries connected to it as well as a network cable for control and HA connected to it using OmniLinkBridge. Over the past week and a half ive been experiencing drops to the connection between the HA and the panel, but i thought that it was just a normal coincidence because i see it sparingly often over the time this panel has been in the church.

Today i got a call to checkout why no one was able to get into the church even with their Keyfobs. I came attempted to use my keyfob, no luck. Manually used a key and got into the church and both keypads were saying this error. I manually reset the panel and removed power from the batteries and unplugged and plugged back in and that's what ive been seeing for the past hour. I did a little research in the forum and check the ethernet lights which I'm seeing activity from and in my router can see that its showing a connection but the IP associated with it has no pings back and forth, no bulging on any capacitors and thats about all i got. Lol.

Would love some help on troubleshooting and narrowing down the problem. Please let me know any additional info you need.

So keypads and keyfobs are all connected over a RS-485 network, and if these wires are shorted anywhere, this will all go down. I would disconnect these 4 wires at the panel, then see if the panel acts better. If you could pull one keypad out and hook it to the panel directly, see if it works. Also, its possible a faulty keypad knocked out all communications, so connect one at keypad at a time to see if a bad one is causing problems.
