I have a couple boxes full of HHP IT3800 Barcode Scanners with the PS/2 connectors on them.

The PS/2 cable is connected to the unit via a 10 pin modular.

I would like to be able to read a barcode and dump it to the debug screen.

Once I have this figured out then I will dump the read to the Nokia 3110 LCD screen and possibly log it to the SD Card.

I have figured out Power, GND, Data, & Clock lines for the scanner.

My issue is I cannot find any wiring or code examples on how to read barcodes.

Do I want to connect the data pin on the scanner to an Analog or Digital input?

Where do I connect the clock line? Pin 13 on the netduino?

I don't think you need to worry about reading the barcode as such. If the reader had a PS2 connector on it then it will be highly likely that it will act as a keyboard. I'd be looking for keyboard drivers. Hope this helps, Mark

Any chance someone could attempt porting this PS2Keyboard Library to Netduino?

Forgot to mention, assuming the scanner has two PS2 connections, one female, one male, you can verify this by connecting the scanner to Notepad. Connect the Male connector to a PC, connect a PS2 keyboard to the female connector. Start the PC and open notepad. Make sure notepad has focus. Grab something with a barcode - say a book and scan the barcode. You should see the barcode decoded and appearing in notepad. Regards, Mark
