8.D.10.d COM Port, BMS
The control has Modbus and BACnet MSTP (RS485) protocols on board, for use with Building Management Systems.
Gateways can be used for other communication protocols.
To navigate to the COM Port Conguration Screen, touch the Misc Icon on the Conguration Screen, then touch
the COM Port Icon on the Misc Conguration Screen. The COM Port Conguration Screen allows adjustment of the
following parameters:
With Modbus protocol selected, the following parameters are adjustable on this screen:
•
Baudrate – Modbus can be congured for the following standard baudrates: 9600, 19200, 38400, and 57600.
•
Address – The address of the unit on the Modbus network.
•
Timeout – Upon loss of communication, this is the duration of time in which the unit will wait prior to timeout conditions
occurring.
With BACnet protocol selected, the following parameters are adjustable on this screen:
•
Baudrate – BACnet can be congured for the following standard baudrates: 9600, 19200, 38400, and 76800.
•
Address – The address of the unit on the BACnet network.
•
Timeout – Upon loss of communication, this is the duration of time in which the unit will wait prior to timeout conditions
occurring.
•
Device Model Name – The name of the unit Model on the BACnet network.
•
Device Object Name – The name of the unit Object on the BACnet network.
•
Object Instance – The object number of the unit on the BACnet network.
