RS-485 BUS PROBLEMS
Solution
Identify device from the location/name and the device
type. Check device addressed correctly to match
programming. Ensure that 2 devices of the same type
do not share the same address. Check connections at
device, and cabling to it. If above correct, re-boot
device, followed by re-boot of End Station.
Part of routine initialisation procedure.
If persists, check display at other keypad(s) to confirm if
device failure at that keypad or complete system RS-
485 failure (temporarily attach additional keypad direct
to End Station if necessary).
Check keypad address, noting that a keypad at address
00 must be present to program system.
Also check "Assigning Keypads" menu in Engineer mode
set up correctly.
Correct addressing so that no overlaps. Then power
system down and up again to correctly reinitialise.
The option 'Allow Engineer Menu' will need to be
enabled by the master manager
