Brad, my client continues to have the problem I have described above. I ran Menu 8 6 from the most commonly used keypad and got a “DataBusErrors Retry T2A2 01925” response. The system had run fine for many years with no such error, and nothing had been changed for some time previous to receiving the errors. No jumpers had been added or removed. There have been no changes in any of the wiring. The system has a single ELK-M1XRF2H expansion module and 2 ELK-M1KP2 keypads. What should I check?
