I have an older, non-functional P800 board, and a newer, locked out P800 board. (Ebay purchase) If I knew for sure which chip was the EEPROM, could I swap them and gain access to programming? The one I suspect to be the EEPROM is labeled "Atmel034".
Thanks.
The eprom has 8 pins. The ATMEL chip sounds right, depending on the board version. Did you try defaulting the panel?
Power down panel Place a jumper from terminal 3 & PGM Power up panel Keypad will beep 3 times within 30 seconds I think. Power down panel Remove jumper Power up and test...
