siemens thingy

[96terrano]

was taking more parts of my old scrap t2 today and found this. i thought it could be somthing to do with the NATS system but im not sure. any ideas?

Yep, I'd say for sure it one of the NATS parts.

I believe it is the receiver for the blip, Rick

It didn't have a blip. Could it be the receiver for the Kay? Because it had a red chip on it:nenau. It was a 1996 swb. The siemens box was behind the glove box when I took it out.

96 I think should have been blip able, but too late to test it now, I have exactly the same box but says gasoline instead of diesel, I have a Mk 1 but it will not program for a blip but the 96 Mk 2 has one, Rick

 

[96terrano]

Yeah because it has 125HZ on it so that must bu the blip freq

125 khz ..... still quite a low frequency though

 

[rayf3262]

125 Khz is for the RFID tag in the key, the antenna for it is the loop around the key barrel.

Would that mean every t2 would have a differant RFID? So for example, you couldn't use the same kay with differant t2s

Every key will have a unique RFID tag, no two keys will be the same.
I believe the ability to "pair" the key with the NATS system can only be performed on a virgin key, one that has not been previously paired with a NATS unit.
The remote "blip" thing is quite independent of the NATS security. The NATS system will work without the key fob battery, quite happily.

If you dismember the key you will find buried in somewhere in the plastic something that looks a bit like a small grain of rice, this is the RFID tag and it is powered from the 125Khz induction loop. The proximity of the key to the "antenna" situated around the key barrel will provide sufficient field strength to wake up the chip in the key fob, then the challenge/response process with the IMMU/ECU will take place.
If yo want to know more check out www.cotag.co.uk, these systems operate on the same principal.

I've always wondered how the little chips are powered I'm interested in electronics lol:thumb2

thanks

Your welcome,...
By the way it's also the exact same technology that the vet applies to your beloved pet, when he "chips" it.
Same small cotag RFID device buried under the skin, just requires a quick scan with the correct tool and bingo you pet is uniquely identified.
