V-Box for Fibo 90cm?

Trouble is, I don't have the facilities to do any machining at all...but I can mod a PCB. I see you've had a look inside the alsat/powertech 500, do you reckon I could tap 5v somewhere?

I've had a look in several different models and they all seem to use the same motherboard, so I guess you will be able to find a 5v supply.
I prefer to use a reed sw., one less wire to run, bit less power to supply, more reliable.
I can help with reed sw, mod if required
 
Hi!
if ,i remeber right,not every vbox "clone" using the same remote code,some is difrent from the orginal!
 
OK, I bought the Alsat/Powertech, as that seems to be the most capable Vbox, and I like the 6 digit readout and overload protection. The motherboard seems to be different from the others I've seen photographed. To start, it's in 2 pieces and doesn't have the large plug in IC. The RF board is of a type I've seen criticized in some threads.

Not impressed by the build quality and if I'd paid the full retail price, I would not be happy.

I noticed that there are 2 blanked off ports on the rear panel. Could these originally have been for 5 volts?

I want to get the Fibo working this weekend, so would it be OK to use any 5 volt supply for now? The reason I ask is that I have seen a thread in which someone claims that just such a supply burnt out their optocoupler, because the 5V should only be present while the dish is turning.

John, I think I will take up your kind offer of help with the reed switch mod. How do I go about this?

Why change the Fibo motor??????

Its so simple to take 5 Volts out of the VBox.
I have do this for manny users and no one have a problem the VBox can run on this way verry simple and also manny years.

Look at my site there is a complete workshop how to change it.

It's a different vbox Snuffer, look at the photographs. I had a look at your site.

Simpel every box named what you will have the 2 relais black boxes also yours i see on the Photo.
Arround that you will find also a 5 Volts piont (best to search around a resistor) Take this for your 5 Volt and test perhaps he switch of the 5 volts and meseure the resitor of the V is drop down if yes remove this resistor and thats it.

Do you have a circuit diagram of it??
Ron


Good luck
 
No circuit Ron and very unlikely to be able to get one. Lets just say that the distribution of this product has some...limitations. But, so that I can get the Fibo up at least, is it safe to use a 5V supply from an adaptor?
 
Yes you can use the 5 volt from a adapter no piont bult hem inside the vbox you have 5 volts are continius there.
