The calibration interface consists of the bidirectional K-line data interface (pin 2), the I/O signal line (pin 4) and power supply
(pins 1 and 5).
The download interface consists of the RS 232 data interface (pins 3 and 6) and ground (pin 1). Please ensure that the transmit
(TxD) and receive (RxD) data connections are crossed over in the download cable so that they can be connected to the serial
port of a PC or notebook with a conventional RS 232 interface. Download devices without their own power supply (download
sticks) also use the EFAS device's voltage supply (pin 5).
