1. General Information
1.1 BACnet MS/TP Introduction
BACnet is a data communications protocol for Building Automation and Control Networks.
BACnet Master Slave Token Passing (MS/TP) protocol is used to relay and exchange
information between building devices. BACnet MS/TP is a based on BACnet standard protocol
SSPC-135, Clause 9. BACnet MS/TP is a peer-to-peer, multiple master protocol based on token
passing. A token is information packets in the form of a pulse signal that is passed between
devices on a network. BACnet MS/TP is exclusive to BACnet and can be implemented using the
EIA-485 signaling standard. This is a shielded twisted-pair (STP) LAN operating at speeds from
9600 bit/s to 76800 Kbit/s. This LAN type is particularly suitable for single controller and low cost
communications.
1.2 Modbus TCP Introduction
MODBUS/TCP is a variant of the MODBUS family of simple, vendor-neutral communication
protocols intended for supervision and control of automation equipment. Specifically, it covers the
use of MODBUS messaging in an “Intranet” or “Internet” environment using the TCP/IP protocols.
The most common use of the protocols at this time are for Ethernet attachment of PLC’s, I/O
modules, and gateways to other simple field buses or I/O networks.

1.3 About GW-2139M
GW-2139M is a network gateway allowing Modbus TCP client devices to be accessed
BACnet MS/TP network as a BACnet MS/TP master. The BACnet Master Slave Token Passing
(MS/TP) protocol is used to relay and exchange information between building devices.
GW-2139M contains a large number of BACnet objects (AI,AO, AV, BI, BO, BV, MSI, MSO, MSV)
gives you flexibility in mapping Modbus TCP registers to any combination of BACnet objects.
BACnet interoperability building blocks (DS-RP-A, DS-RPM-A, DS-WP-A, DS-WPM-A,
DM-DDB-A, DM-DOB-A, DM-DCC-A, DM-RD-A) are Supported. All the data transfer is
configurable using ICPDAS Utility.

Ethernet Port
Terminal Block
The GW-2139M is equipped with a RJ45 port for
Ethernet LAN connection. When 100BASE‐TX is
operating, the 10/100M LED is lit orange. When
10BASE‐T is operating or the machine is not connected
to the network, it is turned off. When an Ethernet link is
detected and an Ethernet packet is received, the
Link/Act LED is lit green.
