Wiegand data and com port

Yes, i guess that the code could be adapted. You only have to write a routine for storing numbers in EEPROM. Only thing that might get disturbing is PIC's oscillator frequency deviation due to temperature. It might affect RS232. Test it before hunting real treasures .)

Good warning on the temperature variation - a larger pic and external xtal (or something like a 16F88 with internal crystal/more acpability than is needed?) might be required.

I don't suppose you could re-post the 12XXXX IC code could you (my email is mac65 <at> cam.ac.uk if you'd prefer to send it by mail) as the web-links above are broken.

Thanks,

Hi.

I have found 2 samples of RFID Readers that have Wiegand and iButton format at the same time! Anyways, with their Control Panel they claim that readers can be 150 meters away.

Did anyone try any circuit to interface such readers with a PIC, with more than a few cm cable? I'd like to put them away.

I just hope that narrow pulses could travel through the long cabling.
