RS232 + RS485
It is possible to combine two previous ways of interconnection and connect two Remote display to one Master
controller concurrently. All the parameters and settings are the same as mentioned above.
5.4.5 Connection process
Remote display after power on automatically tries connect to last known Master (if such configuration exist in
Remote display). Otherwise Remote display starts to search for any Master controller connected. It starts to
search on COM 2 (RS-485) using Master controller address 1 – 32 and continues with COM 1 (RS-232).
Remote display tries two communication speeds 57600 bps and 115200 bps.
During this autodetection process the message “Trying to connect” is displayed on screen. This process takes
approx. one minute.
When incompatible configuration type is found in detected controller, the message “Unknown cfg format COM x
Addr yy” is displayed on screen for 5 seconds and detecting continues with next address in the range.
When detecting finishes with no compatible Master controller found, the message “No connection” is displayed
on screen for 5 seconds and detecting process starts from the beginning and continues until compatible master
controller is found.
Not supported types of controllers or controllers that are not properly communicating are skipped during the
search.
5.4.6 Connection troubleshooting
There are few reasons why Remote display cannot connect to Master controller:
Not supported type of Master controller is connected.
Not supported firmware in Master controller.
Configuration table error in Master controller.
Wrong settings of setpoint COM x Mode in master controller.
Wrong settings of setpoint COM x Communication Speed in master controller.
Wrong connection, wiring, communication fail.
