1. Introduction
Reset IP Address
Press to reset gateway IP
address to the default.
Ethernet Port
10/100 Mbps Ethernet port with autonegotiation and Auto-MDIX. Protocols
supported include HTTP, IP, UDP, TCP,
Modbus TCP and BACnet/IP
Modbus Port
Removable 3-wire isolated RS-485
connection with support for 2-wire
non-isolated devices.
Modbus LED:s
Monitoring of Modbus
transmit and receive activity.
Redundant Power Input
24 V AC/DC 10 VA half-wave regulated design
allows power sharing with other half-wave devices.
Power LED

(Intended for Class II circuits only)
Power DC AC
Input voltage: 24 V 24 V
Input power: 6 W 10 VA
Input frequency: N/A 47–63 Hz
The Anybus BACnet to Modbus Gateway is housed in a metal case that mounts on 35-mm DIN-rail.
Power is from a 24 VAC/VDC (± 10%) source. The half-wave rectified power supply allows sharing of
power with other half-wave devices.
The optically-isolated serial port allows for connection to either 2-wire or 3-wire RS-485 networks, using
a removable 5-pin terminal block. Up to 30 RS-485 Modbus devices can share the serial bus at data rates
2.4 to 115.2 kbps.
The Ethernet port provides a shielded RJ-45 connector. Auto-negotiation and Auto-MDIX automatically matches connections to the attached equipment, thus allowing either CAT5 straight-through or
crossover cable to be used for connecting to the BACnet/IP or Modbus TCP network at 10/100 Mbps.
A resident web server allows for commissioning, and troubleshooting via a standard web browser. A
reset switch is provided for returning to the factory default IP address. LED indicators provide communication status on both the Ethernet and serial ports.
