Serial Port Sharer with PoE
Published on : Monday 24-04-2023
Nimbus Technologies offers the tSH-700 module – a serial port sharer/converter that provides a number of functions.
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.
Two Masters Share One Slave: This function allows two master devices connected to different serial ports to share slave devices. The queries from the masters are queued in the tSH-700 module and then processed one-by-one. Modbus mode can be used to convert the Modbus RTU/ASCII protocols, while raw data mode can be used for DCON or other query-response protocols. Different baud rates and data formats can also be used on the different serial ports.
Application:
1. Accessing a RS232 or RS485 device from PLC & SCADA at same time.
2. Providing redundant output for a serial device Modbus and Non Modbus.
Features
i. Supports baud rate conversion application
ii. Supports two masters sharing one slave port
iii. Redundant power inputs: PoE and DC jack
iv. Tiny form-factor and low power consumption
v. Supports Modbus RTU/ASCII protocol conversion
vi. Built-in web server for easy configuration (HTTP)
vii. Allows automatic RS-485 direction control
