Data transmission by the WIZ-SML-IA module

The WIZ-SML-IA modules are transceivers for point-to-point data transfer in half-duplex mode. They are the

right solution for all those applications in which the so called “virtual cable” has to be implemented, i.e. the
RF connection of two systems with RS232 output (for instance two PCs.) The WIZ-SML-IA module is

available in 12V and 5V version: in the first case the voltage is supplied by a connector with central positive

Vcc, while in the 5V version the voltage is supplied through the input 10 of the data connector. Connected to
the module can be used W232 ADAPTER connector which foresees inside an integrated circuit which shall

care for the conversion of the electric signals from RS232 logic to TTL logic and vice versa.

The module has very small dimensions (4 x 9 cm only) and in its card integrates a 100 kbps XTR transceiver,
a microprocessor which administrates the RF syncronizing protocol and a tuned antenna realized on a

printed circuit. Besides these components is fitted also a confirguration dip-switch with 6 positions and 2

indication LED (supply and operation).

The module is enclosed in a special case which complies with the EN 61000-4-2 rule.
