Luciano,

thanks for the yamar links!

I have requested the full datasheets.
Samples will not be available befor end of Feb.

What I can tell so far is:
It is not going to be a cheap solution and will require some PCB space as there is quite some external components required.
(It's not the "single-chip" solution I was hoping it was)

So for MegaADY this is certainly some sort of overkill if he has to transfer just a "few" bytes at "low" speed over a "short" distance.

BTW.
How do you collect all those links?
Are you searching the web all day?
;-)

and where did you find that image?

I know those machines, we have some of them in our neighbourhood, but they dig for coal, I'm not sure they can be configured to dig for information.

Hi,

The cable length is 2 meters.
I know that it was already asked, but why not a new cable with 3 or more wires?
Can you describe the purpose of the devices?

Is that the power line of a credit card reader?

Also in this forum you have started another thread
about "PicBasic text compress routine".
The format of the data is similar to the TRACK 2 of a credit card.

I hope I am wrong.
