NOTE: If you do not want to use the Mantracourt supplied communications DLL (T24drv.dll) you may be interested
in the following:
We have successfully tested EasyHID which supplies the mcHID.dll which is a great generic way of connecting to
HID devices. This library is free and was written to ease both the programming of PIC devices and create sample
code for VB, Delphi and Visual C++.
The USB interface has also been successfully used with Windows CE but we do not supply any drivers for this
operating system.
LED Indication
Two LEDS indicate Power/Mode and Activity.
The red LED indicates mode and should flash at a 2Hz rate. If any errors are detected with the radio then the LED
will remain lit.
The green LED flashes once for each packet received or transmitted via radio, USB or serial.
