Changing Baud Rate or
Communication Mode Using
Address Switches (between
Modbus and BACnet)
This procedure is only required if Changing Communication Mode using ViewPoint (between Modbus
and BACnet) fails and the PowerScout needs to be returned to a particular communications protocol and
baud rate.
1) Power down the PowerScout (disconnect all voltage leads or the USB cable).
2) Set the rotary Address switches to “F” and “F”.
3) Power up the PowerScout (connect the black & red voltage leads to power or connect the USB
cable).
4) Set LSB to one of the following communication modes:
LSB Address
Switch
Communication Mode RS-485 LED COM LED
1 Modbus* Red On Off
2 BACnet Red On Red On
*Factory Default
5) Next set MSB to one of the following baud rates:
MSB

5 76800 Green Off Green
6 115200 (Modbus only) Green Green Off

fter powering up the PowerScout 3037, you will have 10 seconds to make changes. However, every
time a rotary switch is changed, the 10 second timer resets. After 10 seconds of no switch action, the
settings take effect and the switches revert to the Modbus Address selector if in Modbus mode or MAC
address if in BACnet mode.
FAILSAFE: If all address switches are “0,” the meter is placed in Modbus mode at 9600 baud rate.
Communication registers can be modified for baud rate and for mode.
