1. DCU-11 USB data cable (for k700)

2. Fastport for k750 with all pins onboard. I cut my from origonal DCU-60

3. Ordinal RJ45 phone box

4. RJ45 phone cable

So we start

The task divides to 3 parts:
1. To make a box.
2. Make wire for k700 connector.
3. Make wire for k750 fastport.

1. BOX

Open DCU-11 black box (on cable) and remove all wires that comes to phone and leave only USB wires.
Now we need to connect box's wires to chipboard like on the scheme below:

You also can take big picture (2568x1761)
There are 4 wires in RJ45 box
BLACK
RED
GREEN
YELLOW
And you can connect them in free order.
But for convinience i offer you to connect them in this way:
BLACK - GND
RED - +3.3V
GREEN - TxD
YELLOW- RxD
After that you have this:

So, close the box and it's ready to serve


2. K700 cable
Now we need RJ45 phone cable.
We have to cut it on 2 parts: first is need for k700 and second - for k750.
By default the RJ45 cabels wires have same colors coresponding box's wires.
If not then you have to note wich box's wire comects to wich RJ45 wire. And use this note to know wich wire is wich to connect.
Next we take k700 connector from DCU-11 and remove all wires from it.
Now we take first part of cuted RJ45 cable and prepare the cuted side.
For k700 we need only 3 wires:
BLACK - GND
GREEN - TxD
YELLOW- RxD
We have to connect them in this order:

BLACK - GND ==> PIN # 10 (GND)
GREEN - TxD ==> PIN # 6 (RxD)
YELLOW- RxD ==> PIN # 7 (TxD)
And connect PIN #9 (VPPFLASH) and PIN # 11(DC+) together on k700 connector.
K700 cable is ready to serve


3. K750 cable
Now we need second part of RJ45 phone cable.
In k750 uses all 4 wires.
Let's connect them in this order:

BLACK - GND ==> PIN # 9 (GND)
RED - +3.3V ==> PIN # 8 (VPPFLASH)
GREEN - TxD ==> PIN # 10 (RxD)
YELLOW- RxD ==> PIN # 11 (TxD)
K750 cable is ready to serve


THAT'S ALL
Now you have 2 in 1 service cable for SE k700 / k750 phones.

3. Zwyczajne telefoniczne pudełko RJ45

4. Kable RJ45

Zadanie dzieli się na trzy części:
1. Zrobić pudełko.
2. Zrobić kabel dla wtyczki od k700.
3.Zrobić kabel dla fastport'u od k750.

1. PUDEŁKO

Otwórz czarne pudełko w kablu DCU-11 i usuń wszystkie kable, które prowadzą do telefonu. Pozostaw jedynie kable USB. Teraz musimy podłączyć kable pudełka, to płytki tak, jak na poniższym schemacie:

Możesz również zobaczyć większe zdjęcie (2568x1761)
Są 4 kable w pudełku RJ45
BLACK
RED
GREEN
YELLOW
Możesz podłączyć je, tak, jak chcesz.
Lecz dla wygody proponuje podłączyć je tak:
BLACK - GND
RED - +3.3V
GREEN - TxD
YELLOW- RxD
Tak powinien wyglądać końcowy efekt:

Kabel dla k700 jest gotowy do użycia

Kabel dla k750 jest gotowy do użycia


TO WSZYSTKO
Teraz posiadasz kabel serwisowy 2 w 1dla Sony Ericsson k700 oraz k750.
