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.

Figure 3-10 Gateway Settings
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.
SECTION 3 CONFIGURATION SOFTWARE

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.
