Mega 2560 with Serial Barcode Scanner

Hello everyone!

I'm not very experienced using my Arduino with anything other than LEDs so my final project for school is proving to be interesting. We have lights, buttons, servos, and limit switches, which we've tested and are fine. The highlight of our project is a barcode scanner.

Originally we were going to use a PLC but we felt like we didn't have enough time to debug with it. So now I have a serial barcode scanner in the mail and I've been researching on how to bring it over to this project with the Arduino.

I found this thread which seems to be what I'm looking for but I'd like some more clarification: http://arduino.cc/forum/index.php?topic=21168.0

  1. I understand that I will need a converter to have it use the correct voltages for the Arduino. Is this the correct adapter? http://www.robotshop.com/dfrobot-rs232-ttl-adapter.html

  2. The seller of the barcode scanner told me that it comes with the data cable. Are serial barcode scanners powered by the db9 cable?

  3. From the converter, all I need is the Rx and Tx to the corresponding pins on the Arduino. Anything else?

Thanks! :)

Since that barcode scanner seems to have gotten lost in the mail, I bought one closer to home. I just received it today, it's a Quickscan 6000 Plus barcode scanner with PS/2 connection.

I've done everything in this tutorial but nothing is showing up in the serial monitor: http://playground.arduino.cc/ComponentLib/BarcodeScanner

Is this a hardware issue? I've gone through the manual (http://www.bluestarinc.com/techsupport/Datalogic/QS6000_PLUS_Manual.pdf), but I'm not really sure which setting is appropriate to use here. I've tried changing the baud rate of the scanner to 9600 and tried changing to one of the "Keyboard wedge" settings (page 25). Still nothing. Does anyone know if the factory reset will set it to RS232?

My eventual intention is to do something like this: http://arduino.cc/forum/index.php/topic,134385.0.html but I can't even get the basics to work. Can anyone lead me in the right direction? Thanks.

Sorry, I did not see much information on your post about the Serical .net Barcode Scanner issue. So would you give some more information about what barcode reading in java effects that you are trying to achieve.

HI, I have dozens of pdf document owning barcodes, can I use the C# barcode reading tool you recommended to read and scan the barcodes on pdf document?

Hi, Does it support PDF417 and UPC-A? I need such a tool for scanning driving licenses, my sisters' market also need it.
