tSH-735

Introduction

The tSH-735 module is a serial port sharer with 3 RS-485 ports that provides a number of functions, including "Baud Rate Conversion", "Modbus RTU/ASCII Conversion" and "Two Masters Share One Slave". It has a built-in web server that provides a configurable interface. No console commands are required.

This device has Baud Rate and Modbus RTU/ASCII Conversion features. The Baud Rate Conversion makes it possible communication between master and slave devices. It allows for differences in baud rates and data formats to be sent. Modbus RTU/ASCII Conversion allows for a single Modbus RTU master device to communicate with Modbus RTU/ASCII slave devices through different protocols, baud rates, and formats.

Features

• 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
• Baud Rate Conversion
• Modbus RTU/ASCII Conversion
• Allows Two Master Devices to Access a Slave Device

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

Applications

• Office Lighting Control Application
• Production Line Application
