Hi guys . i bought  a DKU-5 cable and i already know which wire is TX / RX / GND / VcOUT...
My modem is a DG834v2

According to the wiki i have this :

|                                        led
|         Pin 4: RX           ----> ()        |
|         Pin 3: VCC(3.3V)----> ()       |
|         Pin 2: TX            ----> ()       |
|         Pin 1: GND          ----> []      tick led     Front of DG834G
|                                    JP603       |
|                                                   power led
|                                                   |

Now i have some questions:

1) The TX from the cable must be connected to the Modem`s RX or TX ? [Same question to RX ]
2) Since i am using the DKU-5 i should not plug anything in the pin3 , right ?
3)GND from the cable goes in to GND from the modem ?

well , i know almost nothing about eletronics , so i will give this schema to someone who does , but i will need to translate from english , so i need a little help with this questions ...

1) jep
2) correct
3) true
