I don't have a superjack VBox II, but I have a Motek VBox II. I don't know whether they are the same or not, if so, use these instructions:
Take a look at the picture below.
If the back of yours looks like the above picture, then you could proceed based on the assumption that they are similar. Do this at your own risk as they might not be the same.
I have four wires coming in from my Von-Weise actuator on the 10 foot dish.
Black and Red are the two big wires. They should hook to the two inputs on the right of the 4-wire input labeled M1 and M2. They can be reversed if the dish moves the wrong way when you start to move the dish.
I have a Brown and Blue wire also coming from the actuator. They are to be inserted into the left side of the 4-wire input on the back of the VBox II. I have the Blue wire hooked to the top, and the Brown wire hooked to the bottom.
That takes care of the motor control part and supply of voltage.
The coax from the RF-In on the receiver goes to the RF input marked receiver on the VBox II. The RF input marked LNB on the VBox II has a coax that runs out to the dish and hooks into the LNB. If you have a voltage controlled LNB, you are in good shape now.
If Hotbird is your center satellite, and you are pointed to it now, you must go into the receiver setup menu for satellites and mark Hotbird as being controlled by diseqc 1.2 for positioning. Assign a position number between 27 and 49. I would probably choose something in the middle of those numbers, maybe 38 and save Hotbird at that position.
Then find a live transponder on the next satellite to the west that you want to hit (Astra), choose it, and mark it as diseqc 1.2 for motor movement, and then begin to gently bump the motor towards that satellite. When you have found that satellite, and the signal quality is where you want it to be, assign a position number 39 or 40, and save the position.
Continue in the same manner for all the satellites you want to scan in.
From then on, it is a matter of choosing the satellite you want to view and a channel, and click it, and the VBox II will move to that satellite.
Hope that helps.
