1. General Infor m a ti on
1.1 BACnet Introduction
BACnet (Buil ding Automation and Control Networki ng) protocol has been designed specifi cally to
meet the communication needs of building automation and control systems for applications such as
heating, v entil ating, ai r-conditioni ng control…etc. The GW-549x gateways contains a large num ber of
BACnet objects (AI, AO, AV, BI, BO, BV, MSI, MSO, MSV) gives you flexibility in mapping Modbus RTU
registers to any combination of BACnet objects. Multiple BIBBs (DS-RP-B, DS-RPM-B, DS-WP-B,
DS-WPM, DS-COV-B…etc.) are supported. All t he data transfer is configurabl e using a standard Web
browser.
1.2 About GW-5492
GW-5492 is a fully configurable universal Modbus RTU to BACnet/IP gateway. The GW-5492
includes BACnet/IP Server and Modbus RTU Master which is used to make Modbus RTU devices
accessible on a BACnet network.
1.3 About GW-5493
GW-5493 is a fully configurable universal Modbus RTU to BACnet/IP gateway. The GW-5493
includes BACnet/IP Server and Modbus TCP Client which is used to make Modbus TCP devices
accessible on a BACnet network.

2.2 LED Indication
GW-5492/GW5493 provides two LEDs to indicate what situation is in the GW-5492/GW-5493.
They are described as follows.
2.2.1 Power LED
The GW-5492/GW-5493 needs +10 ~ +30 VDC power input and consumes 4.8W. The Power LED
will be turn on after applyi ng power and i t will be flashing two tim es per second.
2.2.2 Module Status indicator LED
The LED indicates the communication status of the GW-5492/GW-5493. The following
description shoes the conditions of error status.
Green light flashes: BACnet Client is communicating with GW-5492/GW-5493
Red light flashes: Time out error on Modbus end
