Application #1 — BACnet/IP or Modbus TCP Remote I/O

Assume that someone forgot to pull MS/TP twisted-pair

wiring to a distant part of the building or that the

specication calls for only CAT 5 structured wiring

cable, a connection can still be made to the BACnet

network. Since the BASremote Master is BACnet/IP

compliant, a simple 10/100 Mbps Ethernet connection

to the IP infrastructure is all that is needed. If the

BASremote Master is located on a separate subnet

from the other BACnet equipment, the unit can register

as a foreign device with a BACnet/IP Broadcast

Management Device (BBMD) located on another subnet

in order to initiate and receive all BACnet broadcasts. If

the Modbus protocol is of more interest, the

BASremote Master supports Modbus TCP as well. If

more I/O points are required, a BASremote Expansion

module can be connected to the BASremote Master

DN port. Up to three BASremote Expansion modules

can be attached in a daisy-chain wiring fashion.
