Figure 142: AUX-Port (Hardware Revision 1.1 = from Serial numbers 0121-
1203, 0122-00198, 0123-00564 onwards) RJ11 6-pol
Pin1: -> +3,3V
Pin2: -> Input/Output 1
Pin3: -> Input/Output 2
Pin4: -> Input/Output 3
Pin5: -> Input/Output 4
Pin6: -> GND
The maximum input voltage is 3,3V. The input signals may be fed from external power sources
or feed directly from Pin 1. If the external power supply delivers more than 3,3V a pre-resistor
has to be fitted. The input resistance of the input is 1,5 k
When using a opto coupler switch, a Pull up resistor of 1,5kOhm has to be used.
Output-voltage: If configured as OUTPUT, every Pin delivers 3.3 Volt/10mA.
