ADDLINK
RF TRANCEIVER/RS232 MODEM MODULE with integral Antenna
The ADDLINK RF Module is a miniature PCB mounting module. It
comes supplied as a complete RS232 Modem (with digital telemetry
and analogue link). The module is an ideal low-cost wireless component
which can be treated as a simple wireless connector, and as such
less experience in radio engineering is required. It provides a
complete high performance RF interface, easily controlled by a host
PC or laptop.
It can provide a reliable serial data communications link that can
be used for many data communications applications, such as controlling
RF alarm systems. The ADDLINK device is very simple to use and provides
an RS232 'invisible link' up to 38K4 baud.
The ADDLINK 112 RS232 Modem contains an integral antenna, which
requires only the power and RS232 signals to control. As it is a
complete product, it already has the complete EMC compliance and
requires no further EMC testing.
