Help Needed with USB RFID R/W module

Gevand

Hello I'm very new to Stamp.

I have a USB RFID R/W module and after downloading the BASIC stamp editor i wanted to see if i can run one of the test programs provided with it. The program is called rfid_rw_test.bs2

After connecting the module via usb to my PC i tried running the code and it said "No BASIC Stamp found".
If anyone could clarify what this means it would be great.

I also tried using the identify command. After the editor finished scanning the identification GUI showed that i had a device connected to COM3 and that loopback and echo were both on NO. There was nothing written in the "Device type" cell. I know that for everything to work both echo and loopback have to be set on YES.
Can anyone explain what I'm doing wrong and how fix the loopback and echo problem?

Thank you in advance, Gevand.

There is no USB RFID R/W module. There's a USB RFID module (#28340) that works with read-only tags and there's a serial RFID R/W module (#28440). There's also a serial RFID module (#28140) that works with read-only tags. Which do you have? The USB RFID module (#28340) has no Stamp on board. There is an SX microcontroller, but it's not user programmable and the module doesn't work with the Stamp Editor as you've found out.

The two serial modules are intended to be used with some kind of microcontroller like the Stamps. You would need a Stamp like the BS2 on a board like the USB Board of Education. You'd plug the serial RFID reader into the Board of Education and your PC's USB cable into the Board of Education and then the Stamp Editor could be used.

If you have the USB RFID module, there is a demo program here and there are links on the Parallax webstore page for the product for documentation and other examples of the use of the module with a PC.

Thanks mike i have 28340,
So i guess its not programmable.
Does the only thing it can do is read tags ID numbers?

Yes, the only thing it does is read tag ID numbers, specifically EM Microelectronics EM4100-family of passive read-only transponder tags or equivalent.
