Diseq Rev levels - the difference ?

Anchises

The Motek motor seems to require DiSEqC 1.2 but my
SkyPC PCI card is defined as spec DiSEqC 1.0 .

What's the difference 1.0 to 1.2 ?
Will the motor work on my card ?

1.0 - supports switching up to 4 inputs
1.1 - supports up to 16
1.2 - up to 16, and motorisation

There is no motorisation in 1.0, so no.

There might be firmware updates on that internet thing for your PCI card to work with 1.2

And then again maybe not

Check the manufacturers interweb site

Thanks for that.

Oh dear - Motors out then :mad:

Have to think this out again.

a duel LNB and a 2 in , one out switch maybe ?
And it's then possible to control the switch with ver 1.0 ?

is there such a thing as an integrated duel switch/LNB -
so you can just treat it like a singlle LNB , and let the card do the switching via DiseQ 1.0 ?

Still that limits me to two sats . No experimenting with the H2H arc......

Searching for other options, I did find http://www.dvbsoft.net/download.php?view.48
which has a software patch for the SkyStar2 to enable positioning.
Wonder if anybody has tried this ?

You could also use a positioner, which is designed for situations such as this (analogue kit/cheap/old boxes, whatever). Moteck make them.

You can use ProgDVB as software and use a Disqec 1.2 Motorised plug in. But many Skystar cards (1 or 2 and compatibles) can't supply the startup current for the Diseqc motor.

I found Motorised operation erratic with my PC Sat card when I installed the plug ins. I have normal FTA receiver on the motor now and Four Way Diseqc (28.2E, 23.5E, 19.2, 13E) on a 80cm dish with 3 single o/p LNBs and one Mishdish Quad LNB for Sky to the Disqec and two Digiboxes.

According to Technisat the SS2 doesn't officially support D1.2 because you can potentially burn out the card - as some people have indeed found. But plenty of other are able to use the modified MiBi drivers without any problems. It's dependent on the version of the card, your motherboard and the diseqc motor and the load on the motor.

Alt. you can drive a diseqc mount via the serial port.

I came across the method to drive via the serial port. Hmmm... could do that .....

I did wonder about the power draw from a Skystat2 ....
Is there a way to buffer the power draw via a power supply/battery ?
I expect not since the power is delivered via the signal cable . how would you inject the oopmh ?

Maybe a different card - designed to drive a motor is the way to go ...
What other pc cards are there that WILL drive a motor ??
And is there still a possible limitation on the motherboard - that might fry it ?

Watty's solution sounds good - 3 single o/p LNBs -
My mounting arm looks fragile - wonder if it would take the weight of 3 lnb bracket + 3 lnbs .....??
I feel an experiment coming on

A power inserter such as a Spaun 1418 might work.

Officially Twinhan supports D1.2.

But it looks like probs with those too. Possible solution is to butcher the motor.

Yes you can "insert power" but is complicated by the fact that an ordinary power over coax won't work. The power is 12 ..14 on Vertical channels and 16 .. 18V on Horizontal channels (which is why sometimes the motor gors faster!).

Connecting a relay and external 18V power direct to inside the motor casing will mean the motor draws no power and always goes full speed. I may try this anyway to speed up motor 1/2 the time anyway....
