To write a program that can read RFID using a rfid board .

[elkuco09]

Hello, my name is paulo and im trying to write a program that can read RFID thru serial cable. The RFID boart that I have is a APSX RFID KIT (Icode 2) RW-310 with C-100 Converter that i bought from Trossen Robotics.com. The main problem that I have now is that I do not know how to make the computer to communicate with the board. I tried the example that you guys have on LabView 7.0 at school but i didnt make it to communicate with each other. thank you, Paulo M.

Hey Paulo,

There's one thing that jumps out. I was wondering if you have the NI-VISA driver on your computer. Can you go to Start->Settings->Control Panel->Add or Remove Programs. And scroll down to National Instruments Software, and click "Change" In this menu, can you look for NI-VISA. You should be able to find it. If you don't have it, you can download it here.

If you do have NI-VISA, Can you perform a loopback test with your serial cable?

If those two work, can you include the example program you were using that didn't work?

Good luck with everything.

hey nick, thanks for the reply.

i do have NI-VISA and as far as the loopback test. it works.

I was using Basic Serial Write and Read.VI from the examples folder. When i ran the loopback test was working but when i connect the serial cable from the computer to the device it doesnt write or read anything. well i dont know if is writing or not but on the screen it doesnt show anything.

but my serial port and cable are working fine.

thanks

Can you get it to work in Hyperterminal? If so, then it probably is probably a matter of using the right termination character in LabVIEW.

In LabVIEW also make sure the serial port settings are set up correctly for the device within the vi (baud rate, etc)
