I got one of these in the mail today, it works with both my sync OVER composite Saturn cable (not csync) as well as my sync on luma PlayStation 1 cable (from the.foo83)

Here's the catch: I'm using it with my new JS Tech 1:2 powered SCART splitter (made a thread about it) and it has a sync stripper inside it, but I'm not sure if I have it enabled right now or not, heh... u_u;

But it works! And is cheap :)

EDIT: I'm not sure if it works with actual VGA/480p and beyond (only tested with 15kHz sources so far), I can try to output 480p on PS2 with it if anyone wants!

EDIT2: By the way, I was using it on a JVC TM-H150CG. The cable I used was a Monoprice VGA to 4-BNC :)

I mentioned 'sturdy' in the title because it feels like this thing is housed in epoxy! It's very dense, I was expecting some cheapo plastic

Actual VGA requires separate H and V TTL sync, so no, it wouldn't work with real VGA. However, some VGA displays are able to accept csync or sync-on-green, which can be passed through SCART. My old Viewsonic CRT did. However, sync-on-composite is probably not going to work.

Yeah, I mean I was honestly HOPING this thing was gonna be for 15kHz sources haha. Convenient and makes for some cheap cheap cables if you've got some dsub to BNC cables sittin' around! I usually cut off sound at the source and put it into a separate distribution amp of its own, so I don't need the audio. That's one thing the dongle is sadly lacking :(

I gotta try it out with S-video soon! It was a rando buy for shits and giggles but I'm happy with it.

Yep. Those were originally manufactured for (EIKI?) projectors.

They are useful for feeding the RGB lines to AV1 on the OSSC while simultaneously feeding sync lines to AV3.

This one and all the others I've seen same to be the same: Optoma. But for all I know it coulda been EIKI prior to that... not very familiar with projectors besides a few brands :o

What do you do to connect it that way, btw? A SCART to 4 pin mini-DIN cable / if so, which brand?

Yeah. It might be Optoma that used them...

Right now, I have a monoprice 5 BNC connected to a monoprice BNC to HD-15 connector. I only connect the RGB lines to the switch and the SCART adapter (on AV-1). The sync lines remain disconnected. That's the easiest way to do it.

4 BNC would certainly work, but I had bought quite a few 5 BNC cables; that's what I have sitting around.

Ah, have you ever tried one of these guys? I have two, heh. ALSO surprisingly good build quality! Gold plated :)

EDIT: AH! So, one of these cables would be wonderful to accompany the Optoma dongle! That RGBS breakout is slightly off topic, I just think it deserves more shine, hah

Where did you find one of these? I can see the image is an ebay link, but can't find the item on ebay.

Is the H sync pin on the vga side wired to the csync pin on the scart side?

This is the cheapest listing for me, I live in Northeast USA. There's other listings on there that may be cheaper for you, they are all around the same price. Try searching 'Hama RCA SCART', even though many aren't Hama I think they may be the originators of it. Could always add another dongle on it for breaking out audio! Those are like $3

The pinout of the SCART to 15-pin RGB / 4 pin mini-DIN out... I'm not sure of. It's an epoxy brick! But so far PS1 and Saturn worked with it, unsure if they were indeed sync stripped or not... I am pretty sure the new 1:2 SCART splitter I have came with the jumpers pre-set for converting to RGBS

For the S-video out, what would be a source that's sending s-video through the SCART pins?

Anyway I'm kinda tempted to throw this into my toolbox just in case I need to integrate something with a SCART cable into my Dsub-15 setup, though I'd also need a SCART coupler given this has a male connector. Then again I'd probably never use it.

Certain camcorders and VCRs, mainly for recording between those devices. SCART can accommodate bi-directional composite video or S-Video, plus bi-directional stereo audio.

Those F to F SCART couplers are pretty cool, with dongles that have directional switching it makes for great cheap Frankenstein cables... I keep all my cables quite short, I've not encountered any signal degradation with couplers/dongles/etc!

I just bought the thing as an experiment to see if it would work, people always worry about pinout before buying random cables blindly, but everything I pick up for kicks always seems to work!

orange808's suggestion definitely made this purchase a lot more interesting and useful than what I initially thought, now that I know it can pass RGB over the s-vid connector as well, that opens up a lot of options

Wait, what? I don't think you can do that. That S-Video connector on that SCART adapter is going to put luma on the sync pin and chroma on red; you'd get a sync signal from luma, but you'd have an unintelligible, encoded signal on red, and green and blue would be disconnected.

Am I misinterpreting what you're getting at?

I might be misinterpreting what orange808 was getting at xD, my mental image was orange using a SCART switch, with one of these SCART + 4 pin mini-DIN dongles plugged into it, with RGB going via 4 pin mini-DIN to OSSC AV1 and sync via HD-15 to AV3? I could have misunderstood orange. It sounded completely cray to me too, but very cool if true.

Either way, the dongle in my OP is cool if you have a SCART switch or splitter and want a HD-15 output for an Extron RGB interface or what-have-you. I wonder if the mini-DIN port on the dongle can pass audio...? IDK if it's standard S-Video on there or what, gotta test said port out still!

nmalinoski do you use the /crt/ Discord?

All my RGB inputs are converted to RGBHV and distributed.

I have a sync stripper and an Extron RGB between the SCART input and the switch. The switch feeds RGBHV out to the rest of my gear.

I use additional sync boxes for displays/projectors that need combined sync or sync on green.

OHHHH, so for this OSSC situation you've got the colors going on a Male BNC>Male SCART on AV1, and the two (or one) sync lines from the same cable going to a male HD-15 w/ female BNC attached to on AV3, yeah? Having trouble visualizing. What's the benefit of feeding the sync to a separate input on the OSSC?

Also, so you're just leaving the mini-DIN port alone, yes? I wonder if it's a versatile port that doesn't HAVE to be YC, and you could use something like this to draw audio out of it (unlikely):
