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).
2)
Set the rotary
Network Address
switches to “
F
” and “
F
” on the PS3 or “
999
” on the PS24.
3)
Power up the PowerScout (connect the black & red voltage leads to power).
4)
Set
SW1
(
PS3
) or
SW2
(
PS24
) to one of the following communication modes:

After powering up the PowerScout 3 Plus, 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.
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.
