Zulu Modem Data Module 2km SMT - 

The ZULU2-T868-SO from RF Solutions is a 868MHz ZULU-2 Smart radio telemetry module in SMT package. This module provides a reliable transceiver based industrial remote switch up to 2000meter range. Two modules are combined to provide a simple network for radio switching. Each unit is supplied ready to operate, once paired with another module a remote control system is created. Connections for power, antenna and input/output are the only connections required. Each module can be set to act as a transmitter or receiver. A remote telemetry system is achieved when two modules are paired together, as transmitter (Zulu-2 Tx) and receiver (Zulu-2 Rx). Each time input changes on ZuLU-2 Tx, it will transmit status of its inputs to paired receiver. Which will set its outputs to follow the Zulu-2 Tx input reply back with an acknowledge signal. Once completed the module will then go to sleep mode. It is used in remote control, remote networking, remote switching and remote traffic lights.
