GT-540P-3GWA-OEM2 user’s manual, Version 1.0, 2013/10 2/53
1. Introduction
The GT-540P-3GWA-OEM2 is the intelligent Active 3G Remote Terminal Unit product.
They are the highly integrated, stand-alone solution for M2M applications. Within the high
performance 32 bit CPU, the GT-540P-3GWA-OEM2 is suit for the hard industrial
environment. It features 3G module, 6 digital inputs, 2 digital outputs, 1 analog input, 2
RS-232, 1 RS-485 and micro SD interface. It can be used in M2M application fields to
transfer the local I/O and Modbus device’s data via 3G/GPRS by the defined period or
DI/AI triggers. The local I/O and GPS data can also be stored in the SD card to become a
remote data logger. For another communication mode, the GT-540P-3GWA-OEM2 offers
the e-mail mode to transfer the data by e-mail via 3G/GPRS for users to choose. The
simple I/O linkage function of the GT-540P-3GWA-OEM2 can reach the real time control
in the local field. It also supports Li-ion battery as another power source when the main
power is failed temporarily. Therefore, the GT-540P-3GWA-OEM2 is an ideal solution for
environmental monitoring and remote device management for M2M applications.
Meanwhile, it is supplied with easy-to-use API and OPC server Software that streamline
application development process, freeing system integrators from dealing with complex
communication protocols of 3G/GPRS and the Internet. In addition,
GT-540P-3GWA-OEM2 has the GPS function to apply in vehicle monitoring system.

zEasy to Establish 3G/GPRS Network Applications
It is a big headache for engineers to establish the 3G/GPRS applications
because the dynamic IP management is required. Applying the
GT-540P-3GWA-OEM2 and M2M RTU center software, the dynamic IP addresses
can be managed between them. The remote 3G/GPRS RTU product would connect
to M2M RTU Center automatically. Therefore, all remote 3G/GPRS RTU devices
can be managed by s single centralized M2M RTU Center software with a fixed IP
address. Moreover, there are M2M API tool and OPC server for engineers to develop
the 3G/GPRS applications by VB, VC or SCADA development tools conveniently
without any IP address management effort.
zActive data transmission
The GT-540P-3GWA-OEM2 with active I/O transmission mechanism can
raise the communication. Unlike the traditional poll communication, it would
transfer the data by the defined time, DI trigger or AI hi/lo alarm. In addition to
improve the way of communication, that can also reduce the AP effort.
zTransfer data by e-mail
Expect for the transferring data by the general communication with the
M2M RTU center, users can choose the e-mail mode to send these data by
e-mail over 3G/GPRS network in the fixed time.
zModbus RTU device connectivity
The GT-540P-3GWA-OEM2 is built-in Modbus RTU protocol. That can
make any Modbus RTU device connect to the GT-540P-3GWA-OEM2. By the
way of GT-540P-3GWA-OEM2, Modbus RTU devices can be used in
3G/GPRS remote system. The max Modbus RTU device can be connected to
the GT-540P-3GWA-OEM2 is three.
zSimple Local I/O link Control
There are I/O built-in 3G/GPRS RTU devices of ICP DAS. Therefore,
these products can be the 3G/GPRS I/O devices. Expect for these local I/O
data can be sent to the host PC, the I/O link function of them help users to do
the simple control in local field. For example: the DI trigger or high/low AI
alarm can driver the DO channel.
zBuilt-in I/O Data Logging
The GT-540P-3GWA-OEM2 provides an external mircro SD interface.
These local I/O and Modbus data are recorded in SD memory card for one
day in a single file.
