Description
The TX2 and RX2 data link modules are a miniature PCB mounting UHF radio transmitter and receiver pair
which enable the simple implementation of a data link at upto 40 Kbit/s at distances upto 75 metres in-building
and 300 metres open ground.
Available for operation at 433.92 MHz in Europe and 418.00 MHz in the U.K., both modules combine full
screening with extensive internal filtering to ensure EMC compliance by minimising spurious radiations and
susceptibilities. The TX2 and RX2 modules will suit one-to-one and multi-node wireless links in applications
including car and building security, EPOS and inventory tracking, remote industrial process monitoring and
computer networking. Because of their small size and low power requirements, both modules are ideal for use
in portable, battery-powered applications such as hand-held terminals.
