Thanks for your purchase IFB-FULLHD/VIM-FULLHD
we will reversion the IFB-FULLHD/VIM-FULLHD and need your opinion on TOSLINK
do you think you need TOSLINK on IFB-FULLHD/VIM-FULLHD ?
we will add 3D glasses interface and remove TOSLINK due to not enough space for board.
let us know your advise

Thanks and regards

I think that be the best idea. Craig should be able to tell you more since he is working on a circuit fort he glasses in the G90.

I don't use the TOSlink on my Marquee Moome card. I doubt many do. It just doesn't make sense to run video all the way to the projector, then audio all the way back to the receiver. I'm sure their are certain setups where it makes sense, but I can't imagine for the majority.

Do you plan to offer an upgrade service for existing V2 and above boards?

Walter: Moome's asking about the Marquee/Sony boards. You don't use either since you have a Barco. Wink

It's never made any sense to me to have Toslink audio on Moome's boards for the reasons Sparky mentioned above.

Kal didn't walter modify a Moome internal card to work in the Barco?

I didn't use Toslink for my previous G70 as well as my current Vision 1. Don't need it at all

The other thing about the TOSLINK is that I can't think of a time where it is not redundant. I mean, every source that I have ever worked on (I think) also has TOSLINK and/or coax digital out. So you can always fall back on the source TOSLINK output right?

Kal, yes I know Moome was asking about the vim and yes I did mod a Moome vim board to use in my Zenith 1200.

I use the toslink out on the vim board because I use an Oppo HDMI switcher for my inputs and it doesn't have separate toslink inputs or outputs and I need toslink for my amps because thats the way I designed them way back when, it's a long story.

by the way, anyone use the contrast pot to adjust the white level?
the factory default is 0.7V for white level on the card~

I definately do as should others to get it right on.

Hmmm, I'd have to look, but it's the video out you're looking for. You have a set of schematics for the vim don't you? You need to readjust the white level after changing the gamma level.

I leave the gamma at its lowest so i dont think i need to adjust the contrast then, right? I just want to measure it to be sure. What pattern do you use to measure? So i just can measure it on the output of the last op amp for the green channel or before it even gets to the first op amp?

You can test it with a 100ire test pattern or any test pattern that has a 100ire peak, then just set the contrast pot until it's at .7v on the scope. Yes you can take it from the ouput of the opamp for the green channel.
