Establishing Communication Protocol
The PowerScout communicates using the BACnet MS/TP or Modbus RTU protocols via the
RS-485/Ethernet interface. To establish communication with a RS-485, the settings must meet the
following requirements:
 The Modbus/BACnet address on the PowerScout and in the ViewPoint software must be set to
the same value.
 The PowerScout meter default serial parameters are:
Parameter
Defaults
Modbus
Settings
BACnet
Settings
Baud 9600 76800
Data bits 8 8
Parity None None
Stop Bit 1 1
Table II-11: Serial Communication Settings
T
he supported baud rates include 9600, 19200, 38400, 57600 (Modbus only), 76800, and 115200
(Modbus only).
NOTE: The baud rate on the user interface (ViewPoint) must match the PowerScout setting. If these
settings differ, the PowerScout cannot communicate. There are no baud rate settings when connected
via Ethernet.
SWITCHING BETWEEN BACNET AND MODBUS MODE
Changing Communication Mode
Using ViewPoint
Using the Comms Setup tab in ViewPoint is the preferred way to change communications modes
between Modbus and BACnet.
Note: The baud rate and serial settings may need to change between Modbus and BACnet. Setting
address switches to “00” will set the unit in Modbus protocol, 9600 baud rate.
If communication fails, see the section Changing Baud Rate or Communication Mode using Address
Switches (between Modbus and BACnet) on the next page.
