Industrial Gateway


  • ​​​Supports Baud Rate conversion application
  • Supports Modbus RTU/ASCII protocol conversion
  • Raw data mode for most query-response protocols
  • Built-in web server for easy configuration (HTTP)
  • Read-cache ensures faster response 


The tSH-700 module is a serial port sharer/converter that provides a number of functions, including "Baud Rate Conversion", "Modbus RTU/ASCII Conversion", "Two Masters Share One Slave" and "Read-Cache Function".
The built-in web server provides easy configuration interface, and no console commands are required.
Baud Rate Conversion:
This function allows a single master device to communicate with slave devices using different baud rates and data formats.

Modbus RTU/ASCII Conversion:
This function allows a single Modbus RTU/ASCII master device to communicate with Modbus RTU/ASCII slave devices using different protocols, baud rates and data formats.
Modbus RTU_ASCII Conversion

Two Masters Share One Slave (for tSH-73x Series only):
This function allows two master devices connected to different serial ports to share slave devices.

Note: It's recommended to have large timeout value and scan interval settings on the two masters, since the slave port is now having double loadings

Read-Cache Function:
The built-in cache function reduces the loading of serial communication on the slave port by removing duplicated queries when the two master devices are requesting the same information.
