SR900 Series
The SR900 Series Wireless Radio was specifically designed for today's telemetry and SCADA application. It is a reliable, cost-effective, license-free radio interface with transceiver frequency hopping from 902 - 928 MHz. This telemetry radio is perfect for any point-to-point and point-to-multipoint serial equipment operation.
The SR900 is field configurable as either a master, slave or repeater and comes with built in CRC-16 error detection and auto-retransmit to provide accurate and reliable data transmission. It has the maximum allowable transmit power (1-watt) with a superior gain of 135 dB allowing line-of-sight communications at distances over 14 miles. Non line-of-sight communication is also possible since the SR900 can be used as a repeater to span the distances for other nodes in the network.
The sixty two different user-selectable pseudo-random hopping patterns support multiple networks and addressing includes station ID and network address. In addition, the user configurable encryption maximizes security and privacy.
The SR900 has a small footprint making it ideal for panel mounting, has digital and analog I/O options available, and it can be configured as either a master or slave with the included, easy-to-use Windows based configuration utility.

TSR900 Series
The TSR900 is the latest generation of industrialized license-free radios and was designed and developed specifically for today's telemetry and SCADA applications. It has all the features of our SR900 plus built-in input output capabilities utilizing the Modbus protocol. The Modbus I/O enables integrators to conveniently use a single device to monitor and control remote stations. The I/O includes 5 digital inputs, 2 digital outputs and 2 analog inputs with additional digital and analog I/O available in various configurations.
