Cytron Technical Forum

Hi forumers,

I have some problems with this RFID reader (Wiegand RFID Reader: RFID-IDR-WIEGAND)

1) does any of you have the datasheet for this product? mind sharing?

2) how to control the buzzer and the LED. the buzzer is too loud, i hope can turn it off without breaking the reader's case. i tried to pull down the cable for buzzer (give LOW signal) but the sound still comes out.


Please help, thank you.

never use that RFID reader before, it seem cheap

You can try to find the buzzer location, seal it, this should be able to lower the volume.

You can refer to PR25 for the sample application and Wiegand Protocol.
