V-Box for Fibo 90cm?

joekir

Hello,

Can anyone recommend a V-box for the Fibo? I have read that they need to have 5v out and not all of them have that. There are some Al sat V500s being sold cheap now, is that a suitable V-box?

Thanks

rolfw

No idea i'm afraid and there seems to be a lack of specification on the site.

hello Jokir and rolph!
good evening,or good morning
there are many difrent vboxes avalible i have a vbox 2 with modification,that you can buy in germany,then you have the 5 volt conector!
my modell is from motek i think not the orginal jager version from taiwan!
on us sites,i also see vbox 3 for selling,also another companyname,here you have 5 conections,without to make a modification!

you can use vbox, but no one can tell me exactly,what the weight limits of the dish allowed in spezification!
but i can say for sure,my dealer told me,my 36 " smo jager motor,with mesh 2,40 m is to heavey for it,if i would try to move with vbox,the fuse protection will be activated,and the vbox maybe get an electronic shock hazard!

nice detail,.not every vboy using the same remote code,difrent source,on the net told,that some modells have the same remote box,then the openbox,if you use it in combination,with this receiver,be very carefull,because,you are controling the receiver,and the vbox,with one remote at the same time!,without knowing it,if you dont rekognize it,in the first moment!

I used a Moteck vbox with my Fibo 1.2m, which I bought from Ebay . Just ask before you buy if it has the +5v

Prodelin

The Darkman ***** V-box 500 is the best of them all i tried.

joekir

But it does not look like it has a 5V out. I agree, the spec looks good, but there is not a lot of info from the UK distribution. I found out more about it by looking at the US version.

joekir

You can find out a lot more about it if you look at the US distibutor. They call it "Powertech V3000". Some good photographs of the back panel and it looks like no 5V

Hi Turok,
A lot of American users seem to be using the V3000 with 3M+ C band dishes.

Turok

Hi!
yes,cband dishes are not so heavey then full size dishes,the dealer told me,when the dish is to heavey (full size),and then wind will come,you move the dish,in this time,vbox could be destroey i never tested it,the selle dont recomend me to use it on smo 36 motor,because,the voltage output,seems to be much lower,then on normal 36 volt receivers !

but what are the difrents in the mainboard layout and compenets between the oginal jager vbox,and the other brands?
are they realy all the same or not?
dont know what i should belive @ the moment..

CROSSBONES

Isn`t the strain on the actuator? Not the vbox? How does driving big dish`s put strain on the v-box?

Turok

the dealer told me,the motor,takes,more power,when the dish is to heavey,during moving,and then the main voltage output,of the vbox could be to low,it can work a long time,but the day could come,that your vbox will gone..
again i never try this,but i can image that this could happens!

CROSSBONES

Surely the max power used would be 36v to the motor? no higher no matter what size of dish? Just bigger the dish the more strain on the jack?

rolfw

Well I guess that the current draw will be greater if the motor is straining, thus shortening the life of the V-Box if it exceeds the output capability.

CROSSBONES

Yes I understand what your saying, but surely there is a max current drawn?

Turok

Hi there!
i would say,when i make a review,in my mind,how this technical process will go.

the motor,gives the first signal impuls,and this one in the first moment,is the strongest,and this "high voltage"in the first secound,of begining to move,is maybe enough,to destroy the vbox!
also the same scenario could happen,when the heavey antena,comes from deep elavation,of eastern and western satelites ,comes back!
because,the antenna,stands @ a very low declinattion level,the motor,needs more power,and more energy ,from the controll unit( vbox),to bring antenna back,into normall position!
same for e.g,happens also on egis motor,when a 3 meter full size dish is to heavey for it,when you try to move antenna back from the deepest eastern/western maximum limit,your controll unit can switch of temporarly,in the worst case scenario,your nitec controller,will also gone,like the vbox! the fuse protection normaly will be acticated,if not your controll unit,will stop working,but normaly the fuse inside should protect it but not always!

if i look in the past,also some staab diseqec motors,take to much power,in the start/end phase,of motormoving!

with the result,that the invacom lnbs 0,3,that was new ,@ the market this time,was very sensitive,about high voltage,this results ,in that,that the diseqec staab motor,destroyes your lnb

because,the motor power impuls was to high for it,and the lnb to sensitive,it only happens,with the combination staab /diseqec/ivacom lnbs straingly!

i need a long time to find the reason,why 3 of my invacom lnbs,are gone,in a relativly short peroid of time!

this is all what i can say at the moment!

also i haead,that for example manhattan reveivers,reotates the motor faster,then others,because,there comes a little bit more power out,then 36 volt,can anybody confirm this!

okay,good night,for now ,until tomorow!

Any V-box worth its salt will have output current overload protection (current sensing). I wouldn't trust a fuse - anything other than a short circuit rather than an overload would probably damage the supply curcuit.

I agree and that is another thing that the *****/Powertech 500 Vbox has going for it. I am tempted to buy it anyway and mod it, especially as it's cheaper than most of the others. Has anyone done this or used the 500 with a Fibo?

Turok

***** Products,are all oem Products under difrent name!
are you realy sure that,the are cheaper then the others?
i bougth the ***** darmotor,then i recogneized later that is the same modell,then the golden interstar,from the germany company,and paid 50€ more with shiping,for exactly the same motor..

the other questions, normal motors has only 5 conectors,my smo 36 jager,has the option,to install the 5.optical sensor,maybe it is a optocopler sensor then?
at the moment i only know that 2 difrent versions of smo 36 exists,one with 5 conections,the normal with 4,now the question,what this 5.conection of the vbox realy use for,when most of the motor dont have this?
the manhattan plaza 550,what iam looking for,does also have ,this 5.conector,but controlls the motor then more exactly?
normal conrolling should also be posible with 4 wires,without using the 5.?
maybe depents,on the motor version!

Using one on my 120cm Fibo with 1224 motor. I like this V-box, has a 6 digit display, counts up in both directions from zero and can name satelites.

Slight irritant for me is that it uses the same remote as the others, I was hoping for a different set of commands as I run two V-boxes.

No reason why it wouldn't run a fibo motor with reed sw. mod.

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 *****/powertech 500, do you reckon I could tap 5v somewhere?

johnsattuk

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!

joekir

OK, I bought the *****/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.

_ttp://www.vetrun.com/forums/showthread.php?t=3917

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.

Its in DUtch but with a google langue page simple to translate.

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