1024_0 v103 and tag 3911_0

Postby LUCA.CARIDA » Wed Sep 12, 2018 6:25 am

Hi guys,
here I come with an issue with my 1024_0 RFID module.

I'm trying to read this tag: https://www.phidgets.com/?tier=3&catid= ... prodid=555

but there's no way to have it detected.
I'm checking from the Phidget control panel and, even if a stick the tag to the box of the reader, that's what I can see.

Any hint? Am I missing something?

I've already installed drivers with Phidget22-x64_1.0.0.20180911.exe

It also made me update the reader firmare.

Thanks,
L.

Have you tried writing to the tag? (Select PhidgetTag for the protocol and type a few letters and click write when the tag is on the box). It's possible you got the writable version (3918_0) instead of the 3911_0.

Hi, thanks for the quick answer. Serendipity helped me out.

Writing the tag with the serie EM4100 protocol, which I supposed it was the right one according to tech specs (https://www.phidgets.com/?tier=3&catid= ... prodid=555), returns me an invalid argument error:

Error writing tag: PhidgetException 0x00000015 (Invalid Argument)

but with the PidgetTag protocol I can write the tag, and then I can read it.

So it's solved, thank you for the hint.

If you're getting invalid argument when writing EM4100, it means that the string you used is invalid for the EM4100 format. You need to choose a string that is a 10 digit hexadecimal string (e.g. 0087f3bc91) so only numbers 0-9 and letters a-f are allowed. With PhidgetTag you can use any ASCII character and it can be any length.

If the tag isn't changing when you try to write to it and you don't get an error message, it might be because it's not a writable tag or it's been locked.
