It is an interface used for communication a PC with a smartcard (original as well as pirate). The Phoenix interface can also be used to update the EEPROM 24(L)C16 on the Multimac II cards (gold wafer cards). This interface require a separate power supply (9 - 30V). Connection with the PC serial port is made by cable 1-1, 9pin connectors, male-female.
