    66The Communicatin Cable is used with the [http://www.abelectronics.co.uk/products/3/Raspberry-Pi/29/Serial-Pi-RS232-Interface RS232-Adapter] that is mounted on the Raspberrys GPIO.

    8 1.) cut the micro USB cable to fit the length, remove the cable coating 3 cm before the open end. Since this cable serves just for power supply, we just use the red (+5V) and the black (GND) cable, cut the remaining two other away
    9 2.) cut 3 cables to length, red (12V), black (GND) and yellow (5V)
    10 3.) cut the RJ45 cable to length, remove the cable coating 3 cm before the open end, cut away the cables for RJ45-Pin's 2,3
    11 4.) connect RJ45-Pin5 (usually blue) with Pin 2 of the Female Sub-D plug
    12 5.) connect RJ45-Pin6 (usually white-green) with Pin3 of the Female Sub-D plug
    13 6.) connect RJ45-Pin8 with Pin5 of the Female Sub-D plug
    14 7.) solder RJ45-Pin's 4,7 with the black cable of the micro USB plug and the other black cable (GND), use               shrinkable tubing for electrical isolation
    15 8.) solder RJ45-Pin1 with the red cable (12V), use shrinkable tubing for electrical isolation
    16 9.) solder the third coloured cable (5V) with the red cable from the micro usb plug, use shrinkable tubing for electrical isolation
    17 10.) Close the Sub-D connector, make sure that there are no short circuits
