@amutsi:
I am Greek, pm me if you don't understand the following.
You need to set your settings in Advanced mode, as user darian23 pointed a few messages before. What he didn't descibe is what you need to setup to also make motor work with the same cable.
You will need to setup all other satellite positions as LNB 1, one by one. You'll setup one first, then just set all other satellite positions as LNB1. You will configure LNB1 as:
DiseqC mode: 1.2
Command order: uncommitted, committed, toneburst
Uncommitted diseqc command: input 1
Use usals for this satellite: yes
Also set your longitute and lattitude for USALS mode.
If it doesn't work with this, you might need to also enable Sequence repeat. I don't remember if Diseqc 1.2 USALS command is sent in start or end of the sequence. If it is sent at start, you will need to enable sequence repeat.
