General Description
The WD01 wireless controller has been designed to
offer flexibility and ease of use while ensuring reliable
point-to-point or multi-point data communications.
The WD01 can be used to create a complete wireless
data network or it can
function stand-alone, providing complete turn-key
solutions to wireless applications.
The WD01 accepts a range of RF modules ranging
from 150MHz to 915 MHz with power levels from
10mW to 100mW.
This provides flexibility for the application to
be used in a variety of applications and
geographical locations by simply plugging in the
appropriate RF module.
An RS232 Serial link to the controller is provided
that operates at 19200 Baud. This link can be used
to control hardware functions on any WD01
connected to the network and to upgrade the
operating firmware while the unit is running.
A dedicated ISCP connector is also available that
allows direct programming of the onboard micro
controller using Microchip PICSTART or similar
programmer.
