Yes, it works! (without any pull up resistors) =)

And: It is possible to upload software to the arduino without cutting the RX -> Pin 9 wire. Just put a diode between the RX pin from the arduino and the pin 9 from the ID12 module. It works great!

Best, Edo

To zach:

If you’re using pull up resistors and still getting FF’s, your problem is that you’re in Wiegand26 format output. Change the output to Ascii mode as I described in my last post.

To solve the ffff’s problems you have to use pull up resistors.

There’s another problem with this IC.

You MUST disconnect the power supply pin of the IC and connect it to GND. After this step the IC takes the new configuration of the format selector pin (7). (5v – Wiegand26 ; 0V – Ascii; PIN 10 – Magnet Emulation). This is because the reset pin doesn’t work as expected.

You don’t need to use pull-up resistor in Ascii Mode.

I have the same ffff problem….

The thing is that the ID12 isn’t responding to changes in format pin… in other words the output is always in Wiegand26 format. (I have a logic analyzer).

I don’t know what I’m doing wrong (I’m using pull ups resistor and connect the format pin to GND!

HEEELP!

i am having the same ffffff problem, i tried a pullup resistor but it doesnt work any suggestions?

I have a problem with the ID-12.
i connect pin 9 through the Max232 to the computer serial port to see the readed Tag code on the hyperterminal.
when power on the led goes red even there is no tag to read.
and the hypertermial didn’t receive anything (if the tag exist).
can anyone explain this to me?did the ID-12 IC blow up.
