ICP DAS tGW-735i Modbus/TCP to RTU/ASCII gateway with PoE

The ICP DAS tGW-735i is a small Modbus/TCP to RTU/ASCII Gateway with PoE and 3-port RS-485. It enables a Modbus/TCP host to communicate with serial Modbus RTU/ASCII devices through an Ethernet network and eliminate the cable length limitation of legacy serial communication devices.

The module can be used to create a pair-connection application (as well as serial-bridge or serial-tunnel application) and can then route data over TCP/IP between two serial Modbus RTU/ASCII devices, which is useful when connecting serial devices that use Modbus RTU/ASCII protocols and do not themselves have Ethernet capability.

The tGW-735i module features a 32-bit MCU to enable efficient handling of network traffic and has a built-in web server that provides a management interface for users to modify the configuration of the module.
