1.4 PROTOCOL SELECTION
The D-100 Dual Network Flow Display is provided with an IP connection and a single RS485
connection. Both MODBUS TCP/IP and BACnet UDP/IP are always available from the IP
connection via a single IPv4 IP address. The RS485 connection can be congured for BACnet
MS/TP or MODBUS RTU. The protocol options are selected via dip switch settings. The table
below identies the dip switch settings for each protocol. The switch settings also control
which network is allowed to remotely reset totals on the network.
