| 9 | - Alternatively, use the Raspberry's GPIO and a RS232-Adapter (e.g [http://www.abelectronics.co.uk/products/3/Raspberry-Pi/29/Serial-Pi-RS232-Interface this one]). |
| 10 | - use a micro usb plug, cut the 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 |
| 11 | - cut 3 cables to length, red (12V), black (GND) and a third color (5V) |
| 12 | - 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 |
| 13 | - connect RJ45-Pin5 (usually blue) with Pin 2 of a Female Sub-D plug |
| 14 | - connect RJ45-Pin6 (usually white-green) with Pin3 of a Female Sub-D plug |
| 15 | - connect RJ45-Pin8 with Pin5 of a Female Sub-D plug |
| 16 | - solder RJ45-Pin's 4,7 with the black cable of the micro USB plug and the other black cable (GND) |
| 17 | - solder RJ45-Pin1 with the red cable (12V) |
| 18 | - solder the third coloured cable (5V) with the red cable from the micro usb plug |
