T24-GW1 - Wireless Telemetry Modbus Gateway

Image T24-GW1

The T24-GW1 is a Modbus interface gateway that provides a simple interface for users to gather data from up to 100 acquisition modules in a T24 network using either the standard Modbus interface RTU* protocol or a simple ASCII protocol.

Some simple commands are available to wake, sleep, and keep awake T24 acquisition modules.

The licence free 2.4GHz direct sequence spread spectrum (DSSS) radio telemetry technology offers high integrity, error free communications which can co-exist with other wireless technologies such as Wi-Fi, Bluetooth® and Zigbee®. ETSI, FCC and IC approvals.

*Modbus is a serial communications protocol which was originally designed for use with PLCs (Programmable logic controllers). Over time its simple and robust nature has made it a communication protocol standard. It is now amongst the most common available means for connecting industrial electronic devices.
