Rs485_Bus Settings - DEGA UDA III User Manual

6.11.15 RS485_BUS settings

RS485 interface for connecting DEGA transmitters to the control panel. The control panel contains a total of 4 interfaces
marked RS485_BUS #0 to RS485_BUS #3. Depending on the settings, it is possible to use the individual interface as separate 4
segments or to connect two interfaces as one redundant segment. For redundancy mode, BUS #0 and BUS #1 or BUS #2 and
BUS #3 are connected to each other - the RS485 line starts on one interface and ends on the other. Thanks to this, the control
panel checks the correct function of the line and, in the event of a fault, detects an error without interrupting communication
with the transmitters.

Tip: The transmitter initialization timeout value should take into account the number of transmitters connected to the control panel - the
value in seconds should be higher than the number of configured transmitters.

Description
After the start, the control panel waits for the transmitters to
start up and initialize. After this time, the control panel marks
the transmitters that failed to initialize as faulty.
