TX2 & RX2
UHF FM Data Transmitter and Receiver Modules
The TX2 and RX2 data link modules
are a miniature PCB mounting UHF
radio transmitter and receiver pair
which enable the simple imple-
mentation of a data link at upto 160
kbit/s at distances upto 75 metres in-
building and 300 metres open
ground
.

Features:
CE certified by independent Notified Body
Verified to comply with harmonised radio standard EN 300 220-3 by accredited Test Laboratory
Verified to comply with harmonised EMC standard EN 301 489-3 by accredited Test Laboratory
Data rates up to 160 kbps
Usable range up to 300 m
433.92 MHz versions.
Fully screened
Available for operation at 433.92 MHz in Europe (including UK), 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.
