OT: Winfast TV input card; s-video pinouts?

[Jules Richardson]

I've got a PCI Winfast 2000 XP TV card here that I want to use to digitize video via the s-video connector. It's one of the boards with a short/tall form-factor, and so has a 6-pin s-video connector (not the 9- pin that the long/thin board variant uses, and which seems to be better documented on the 'net).

Does anyone happen to know the pinouts for this connector? Is it the same as:

(except that in this case it's an input, not an output)

I'm not sure how forgiving this kind of thing tends to be if I were to mix up grounds and signal lines, or composite/Y/C signals, but I'd rather not break anything :-) (I've got the manual, but it doesn't give the pinouts, and any kind of breakout cable which may have origianlly come with the board has long gone)

Jules: a bit of googling reveals that that card SHOULD have an adapter lead that breaks out a 4 pin SVIDEO input and a coax composite video. Pins 5 & 6 are comp video ground and comp video.

Its a mirror of this I think

since there is nothing to short out being an input, Id say you can pretty much experiment. Also the grounds are PROBABLY all connected.

Yeah, acquired the card in a machine yonks ago, but no cable (even though the previous owner did have the manual, remote, microphone etc.). I'd almost forgotten that I even had it.

Yes, I think so - I pulled the board and pins 1, 2 and 5 are all connected to the board's ground-plane, and I've since confirmed that pin

6 is indeed composite input.

Unfortunately I'm not getting any s-video input via pins 3 and 4. Either my source is snafu, or the s-video input on the board is, or there's some software quirk on the playback side specific to using the s-video input (and I doubt it's the latter).

Maybe using composite will do what I need; the picture was very grainy earlier, but that was using a right bodge of an unshielded cable with bare wire ends poked into the socket on the Winfast board just to see if I got a signal at all, so hardly surprising.

I don't have any other 6-pin mini-DIN plugs in the junk pile (the one I was using for testing the s-video input lacks a pin 6, i.e. the composite signal input) - I think I'll mount a 3.5mm jack socket in a PC blanking plate adjacent to the Winfast board and run a short bit of wire from it direct to the board's PCB. (I *think* I have a PC video card somewhere - ATI, possibly - that has S- video output; if I get really board I might throw that in another PC and see if I can feed a signal from it to the Winfast, which would at least pinpoint where the problem is)
