UCG PROTOCOL SETUP
4.2.1
CONFIGURE THE DIP
SWITCHES
DIP switches on the ProtoNode, located
inside UCG, may need to be set for the
appropriate devices and communication
settings. These DIP switches are factory
preset when the field device and protocol
are known at the time of ordering. If
needed, remove the cover of the
ProtoNode located inside the UCG.
Note: If the DIP switches need to be
changed then the power to the unit will
need to be shut off before proceeding.
4.2.1.1
BMS PROTOCOL (DIP SWITCH S0
– S3)
The S bank of DIP switches (S0 – S3) are
used to select BACnet MS/TP, BACnet IP,
Modbus TCP, or Metasys N2 configurations
on the UCG (RER). The “S0 – S3” bank of DIP
switches on the UCG (LER) (LonWorks) are
disabled. See Table 2 below and set S bank
Dip switches to the desired configuration.

SETTING THE SERIAL BAUD RATE
DIP Switches B0 – B3 can be used to set the
serial baud rate to match the baud rate
provided by BMS. See Table 4 for B bank
configurations.
