Introduction
WIZ2-434-x modules allow to connect, via radio, two or more units; they supply a complete radio frequency
system, by integrating receiver, transmitter and antenna and by indipendently administrating a low level
packaging of the data sent from a control unit (for instance a Personal Computer), and the managing
functions of the radio link interconnection.
They are supplied by a voltage ranging from 9 to 15V.
A 96 bytes maximum length data packet can be sent to the transmitter module by a personal computer; the
data to be transmitted are memorized in an input buffer and forwarded to the remote connected WIZ2
module, to which are addressed.
The packet received by the WIZ2 module will be decoded, stored in the reception buffer and, in case,
confirmed. It shall be forwarded, then, to the downstream connected unit, through a serial port.
The WIZ2 modules bear a
polling
system where a master unit can address up to 255 slave units.
The host personal computer dispatches, to the WIZ2 module, the data preceded by an address byte of the
remote module; the data exchanging administration unit adds the preamble and error control bytes.
