Using Pi Option; Sio Chip Soldered On Pcb; Sam Card Connection - Elatec TWN4 MultiTech Mini Manual

4 Using PI Option

4 Using PI Option
To use the PI Option, e.g. to read the PAC bits from an iCLASS transponder, a SIO processor is needed.
This can be either a SIO chip which is soldered directly on a PCB or a SAM card incorporating the SIO
processor.

4.1 SIO Chip soldered on PCB

The SIO processor has to be added to the design of the mainboard. The chip shall be connected to the
SAM-pins of the TWN4 Mini Reader.
Recommended schematic:

4.2 SAM Card Connection

A SAM socket has to be added to the design of the mainboard. The SAM socket shall be connected to the
SAM-pins of the TWN4 Mini Reader.
Following SAM sockets are recommended:
• Molex 47388-2001
• Molex 47308-0001
