SECTION 1 GENERAL INFORMATION
1.1 General Information
GTOR series products connect to serial MODBUS devices with TCP / IP based
systems via GPRS service. In this way, it is possible to remotely control and monitor
serial devices connected to MODBUS network via GPRS service. GTOR can be easily
integrated into existing MODBUS networks thanks to their wide range of configuration
options.GTOR series products works as a TCP / IP server, allows 4 MODBUS Gateway
connections and 1 configuration connection.
Server Mode:
GTOR converts MODBUS TCP or MODBUS RTU over TCP and MODBUS ASCII Over TCP
queries received via GPRS to MODBUS RTU and MODBUS ASCII queries and sends
them to serial devices via built-in RS485 / RS232 interface.The response from the
serial devices is converted to the request protocol and sends it to the querying device
(master) via TCP / IP.
It provides configuration via USB or TCP / IP using GPRS service. The on-screen LED
shows a lot of information such as power, signal strength level, operating status.

power connection.To use the“GatewayMaster”program; this port must be connected to
the computer. However, GPRS functions of GTOR will not work when GTOR is energized
via USB.
The GTOR scan for 5 seconds at startup to see if the Micro-USB cable is plugged in, and
the RX andTX LEDs will blink during this time. If the micro-USB cable is plugged in, the RX
and TX LEDs are always on and the GTOR is ready to be configured via “GtorUSBConfig”
via USB. If the Micro-USB cable is not plugged in, the RX and TX LEDs will go out and the
GTOR is prepare to perform its basic functions.
RS485 Port:
Provides, communication with serial devices that MODBUS RTU and Modbus ASCII
protocols supported.
Antenna:
The SMA type connection where the external antenna connection is made.

Port:
The TCP port that GTOR will listen to.
Request Type:
The type of MODBUS queries that are sent to the GTOR over the GPRS network is
determined by this field.
“MODBUS TCP”,“MODBUS RTU over TCP” and“MODBUS ASCII over TCP”protocols are
selected.
Response Type:
The type of MODBUS responses to the GTOR via the serial link is determined by this
field. One of the“MODBUS RTU”and “MODBUS ASCII”protocols is selected.
Request Timeout:
In server mode, if a new query does not arrive in GTOR until the query “timeout”
expires, the GTOR will close the TCP connection with the sending machine and
allocate resources for new TCP connections.
If the time between two queries is greater than the timeout expired on the query
side, a new TCP connection must be opened before the query is sent.

GPRS/SerialGateway
Response Timeout:
In GTOR’s MODBUS network, it is the response waiting time from each serial device
that is interrogated. If no response is received from the querying device during this
time, the next remote connection query is passed.
Server Mode Communication Example:
In this scenario, it is desired to take data from a device that accepts MODBUS RTU
query using a computer that is connected to the network. MODBUS software in the
computer can create MODBUS TCP queries only from port no. 502. In this case, in
oder to have a healthy data communication, the following steps should be taken:

1. The MODBUS TCP query created by the software on the computer is sent to the
network via the GPRS.
2. The GTOR connected to the same network takes the MODBUS TCP query via GPRS
and turns it into the MODBUS RTU query.
3. The GTOR transmits the query to the serial device via the serial port and waits until
the timeout expires (assuming 1 second is suicient for this scenario).

4. The serial device transmits the data corresponding to the MODBUS RTU inquiry
from the GTOR to the GTOR from the serial port as MODBUS RTU response. The
GTOR takes the MODBUS RTU response from the serial port and translates it into the
MODBUS TCP response.
5. GTOR sends the converted MODBUS TCP response over the GPRS network.
6. The software on the computer informs the user of the use of the MODBBUS TCP
respond received from the network.
