as I could read here a season like dummy smart card connected to the serial port at the pc is one possibility to program a matrix reborn cam. I also could find so called "twin programmers", e.g. http://www.alphasat.ch/shop/product_...c27fd517e1540d
I have to questions concerning such programmers:
The first is if there is a circuit diagramm available to build such a programmer by myself.
The second is, can a programmer like that also be used as a season interface ?
Thx for reading and possible answers
