1.4 PROTOCOL SELECTION
The System-10 Dual Network BTU Meter 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 configured for BACnet
MS/TP or MODBUS RTU. The protocol options are selected via dip switch settings. The table
below identifies the dip switch settings for each protocol. The switch settings also control
which network is allowed to remotely reset totals on the network.
