Overview
WL-TX/RX-900 modules provide an economical method to transfer industrial signals
over long distances (using radio signals in the license free band). They can be used
for Analogue current/voltage and Digital signals. Transmission is one-way (from
Transmitter to Receiver).
WL-TX/RX-900 modules are available as transmitters (WL-TX-900) and receivers
(WL-RX-900). The transmitter monitors its analogue, thermocouple and digital inputs
and transmits the information to one or more receiver units. The receiver units
reproduce the signals at their outputs according to the configuration. Linking one of
the Transmitter inputs or internal variables to an output on a Receiver module is
known as mapping.
Transmitters and Receivers include a default setup to work as a pair. The default
setup maps the most commonly used Transmitter inputs to the Receiver outputs. You
can setup more complex applications using the configuration software via the RS232
RJ-45 serial port on the front of the unit.
