Description
The RF620 Smart Radio modules provide low cost reliable wireless data communications.
The modules enable a simple ‘plug & play’ solution, providing a direct radio link for either a serial data stream
(CMOS/TTL) or 2 remote control telemetry lines.
The modules contain integrated microprocessors which perform the necessary encryption to optimise the data
for transmission by radio. This ensures the maximum range and reliability.
In the non-learned mode, all RF620R receiver modules within range of the. RF620T transmitter module will
transparently decode and output the data sent to them over the RF link.
If a secure point to point link is required then the RF620R receiver can be matched to the RF620T transmitter
by a simple learn procedure. This also allows several separate point to point links to communicate
consecutively in the same area.
Possible applications include 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.
