Description
Following the success of the original tGW-700/tDS-700 modules, ICP DAS has continued to develop new functions for these products in order to provide increased support for a greater number of applications. The tSH-700 module is a serial port sharer that provides a number of functions, including "Baud Rate Conversion", "Modbus RTU/ASCII Conversion" and "Two Masters Share One Slave". 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. Most query-response protocols (half-duplex), e.g. DCON, are supported in the raw data mode. Full-duplex communication should also work when the data size is smaller than the built-in 512 bytes buffer on each serial port.
- 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.
Features
- Supports Baud Rate conversion application
- Supports Modbus RTU/ASCII protocol conversion
- Supports two masters sharing one slave port for tSH-73x Series only
- Raw data mode for most query-response protocols
- Built-in web server for easy configuration (HTTP)
- Redundant power inputs: PoE (IEEE 802.3af, Class 1) and DC jack
- Allows automatic RS-485 direction control
- Tiny form-factor and low power consumption
