LF Dual modulation FSK and ASK

I'm trying to clone a lf key by a company called ISONAS.

They claim their keys are "Dual modulation with FSK and ASK". I have never heard of this but it's taking me for a loop on how to clone.

Here is a link to the documentation I could find.

I've run every test I could find without results.

Is it even possible to have both FSK and ASK?

Re: LF Dual modulation FSK and ASK

The datasheet is about the reader that is both dual frequency (13.56MHz-ISO14443-only & 125kHz) and dual modulation (ASK and FSK); you should find the spceific key datsheet. From that datasheet ISONAS seems to be together with HID so probably their ISONAS tags are 125kHz.

Re: LF Dual modulation FSK and ASK

Thanks for the tip, I know it is definitely 125Khz but I cannot find a datasheet on it anywhere, I haven't even heard of isonas until now.

Tried a data plot, and am fairly confident it isn't Manchester encoded - I can't figure out what the heck it is. I've also tried fskdemod and Indala to no success.

Any suggestions?

Re: LF Dual modulation FSK and ASK

Well, THIS is surely a good public datasheet available you seem to have missed... from it you can see it is an UID-Only 125kHz card (look at the thick shell); form this other public datasheet you can see the "badge ID" is a 5-numbers-only ID.

Now you can try, for example, those commands in sequence:

lf read
data samples 5000
lf indalademod (or others)

and see if you obtain something (maybe the number written on your tag - you did not mentioned if you have one or not).

Re: LF Dual modulation FSK and ASK

Nope, I didn't miss that. It doesn't really say much. UID only still doesn't tell what it is encoded with.

The first thing I did was indalademod, no joy.

Any other ideas?

MnBadger, do you still work for Farpointe?

He never worked for farpointe.  The one post almost makes it sound like it but there were several other posts that have been removed that explained who he works for.
