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.
