2 - BACnet Setup (cont.)
2.3 - Select field protocol
Select the desired field protocol: BACnet MS/TP, BACnet/IP, Modbus/TCP, or Metasys N2 via S bank DIP switches for ProtoNode RER
(FPC-N34 BACnet).
2.3.1 - Using the S0–S3 bank of DIP switches
•
The S bank of DIP switches, S0–S2, is used to select BACnet MS/TP, BACnet/IP, Modbus/TCP, or Metasys N2 on ProtoNode RER.
•
The S3 DIP switch is used to enable Auto Discovery of known devices attached to the ProtoNode RER, as well as save the recently
discovered configuration. When the S3 DIP is Off, the ProtoNode will load the current saved configuration.
Turn S3 to On if the
ProtoNode is being installed for the first time.
•
The following chart describes S0–S2 DIP switch configuration settings for the devices to support
BACnet MS/TP or BACnet/IP
on a
ProtoNode RER.
•
When the S bank of switches are all off (default setting), BACnet/IP is enabled.
•
The OFF position is when the DIP switches are set closest to the outside of the box.
