Connections (USB)
The Parallax RFID Card Reader USB version can be connected directly to any PC, Macintosh, or Linux
machine that has a USB port and the appropriate drivers installed. The module is powered from the host
computer’s USB port and uses an industry-standard FTDI FT232R device to provide the USB connectivity.
FTDI drivers are available from www.ftdichip.com/Drivers/VCP.htm.
When the Parallax RFID Card Reader is connected to the host computer, it will appear as a Virtual COM
port and will have a COM port number automatically assigned to it. This COM port can be accessed by
any software application, programming language, or interface that provides COM port connectivity and
will allow you to read the data stream transmitted by the module.
An example program, including Visual Basic/VB.net source code, for reading tags in Windows XP/Vista is
available on the Parallax website at http://forums.parallax.com/forums/default.aspx?f=21&m=269675.
The DEBUG window within the Parallax BASIC Stamp Editor (www.parallax.com/tabid/441/Default.aspx)
provides functionality to set the state of a COM port’s DTR line. Checking the DTR box in the toolbar will
activate the RFID Card Reader.
