Hi,
I have come into a surplus of ADT 148495 (focus) alarm keypads and
see that it has an RS485 interface and rom a prior newgroup post, I
believe it is 4800-7N1 baud. Can anyone point me in the direction of
information about the actual protocol used to drive the RS485 bus? I
am basically interested in the addressing scheme, getting text to
display, and getting the user input from the keypad to my RS485 PC
(without the main panel).
Thank your for your time!
