Re: SCART to D-SUB 15 (DE15) adapter
...so, anyone tried this? It seems to essentially be a primordial Sync Strike, long forgotten. I've never, ever heard it mentioned in gamer circles. Quite curious about it!
Re: SCART to D-SUB 15 (DE15) adapter
Are you sure that monoprice cable is bi-directional? Also, if you were just using RGBS, would that work since it's RGBHV? I have a similar situation as OP, except I'm trying to get scart into an Extron RGB. I think I'll probably go with the scart2dvi, but if that monoprice cable would work, I already have everything I need, even if the cabling would be pretty inelegant.Guspaz wrote:I didn't realize that the board was unpopulated. They do sell the SCART connector separately, and you could cut open a VGA cable and solder it to the SCART connector, but for the simpler solution, the BNC-to-SCART adapter for US$26:

The Monoprice cable is just a basic adapter - there are no electronics and it'll work in either direction.jamon1567 wrote:Are you sure that monoprice cable is bi-directional?

RGBS will work fine through an Extron VGA switcher, just run composite sync through the Hsync pin. I use this setup myself, although I'm not a big fan of SCART so I just made dedicated DB15 cables for my consoles.

Re: SCART to D-SUB 15 (DE15) adapter
To add to this, SCART and, to a lesser extent, JP21 are really the only directional cable types we (gamers) might have to deal with, and that's because they were designed to accommodate bidirectional communication between AV recording devices, such as transferring audio and video between a VCR and a camcorder using the same cable.matt wrote:The Monoprice cable is just a basic adapter - there are no electronics and it'll work in either direction.jamon1567 wrote:Are you sure that monoprice cable is bi-directional?

I think I'll probably go with the scart2dvi, but if that monoprice cable would work, I already have everything I need, even if the cabling would be pretty inelegant.
Specifically, that accommodation resulted in separate sets of wires for left channel audio, right channel audio, composite video/luma, and chroma all in the same cable that get crossed over, meaning a given SCART device has a set of pins for sending each of those signals to another device, and it has a second set of pins for receiving all of those signals from another device, and the pins for output on one end are connected to the pins for input on the other end.
That results in a cable that is not straight-through on all pins, like most every other cable type we have to deal with. All pins on DE-15/VGA, BNC, RCA, F-type, TOSLINK, etc. cables are connected to the same-number pin on the other end; So, if, for example, you put a signal on pin 3 in a VGA cable, it will come out on pin 3 on the other end. If, however, you put sync on pin 20 on a SCART cable, it won't come out on pin 20 on the other end. This is why RGC's SCART to BNC adapters have a switch; so it can route sync from SCART pin 20 to BNC H/CS, or sync from BNC H/CS to SCART pin 19 (maybe audio, too; I don't have one of these to crack open and check).
Re: SCART to D-SUB 15 (DE15) adapter
Can someone share the details on scart2dvi output?
I assume it is an all analog circuit that outputs RGBHV on a DVI-I connection? (Not a transcoder that samples the input, processes it in the digital domain, and runs it through a DAC?)

Re: SCART to D-SUB 15 (DE15) adapter
I wanted to make sure because I have this cable that I use with my gscartsw 3.4 to output to my monitor/crosspoint, yet when I tried to connect my crosspoint to the Extron RGB using this, it didn't work. It even says on the site it's HD15 --> BNC exclusively, so I thought this other adapter may be similar.

Re: SCART to D-SUB 15 (DE15) adapter
That's weird. It's possible they added some electronics that make it directional, but why?jamon1567 wrote:I wanted to make sure because I have this cable that I use with my gscartsw 3.4 to output to my monitor/crosspoint, yet when I tried to connect my crosspoint to the Extron RGB using this, it didn't work.

I'd grab a multimeter and check that pins 1, 2, 3, and 13 are connected to red, green, blue, and sync respectively, going both ways (black on DE-15, red on BNC; then black on BNC, red on DE-15), then, out of curiosity, I'd see which pins are connected to ground.
If that testing works one way, but not the other, I'd complain to Monoprice, because directionality is not actually in the item description and was unknown to you before you bought it (ostensibly based on the description). If, however, the testing works both ways, that would confirm it's a passive cable, and there's something else to your Crossspoint/RGB interface problem.
Re: SCART to D-SUB 15 (DE15) adapter
Well, I bought it a while back specifically to use with my gscartsw, so I don't really have any valid complaint. That said, it was mentioned in the QA that it isn't bi-directional. I didn't, however, see that for the other adapter which is why I was curious.nmalinoski wrote:That's weird.

Edit: actually I correct myself. For the VGA --> 5 female BNC, it says in the QA that is only VGA --> BNC as well. I think maybe I was thinking of a similar product by another brand that I was looking at on Amazon where it wasn't clear.
Re: SCART to D-SUB 15 (DE15) adapter
On a side note. I'm leaning towards purchasing the scart2dvi, but I was wondering if anyone knows if there are cases available for it? I emailed Insurrection and they said they don't have any, nor are they aware of any existing, but I saw on RetroRGB's site that he said cases will be available at some point in the future. Anyone know of any?
Re: SCART to D-SUB 15 (DE15) adapter
I can't get output from my gscartsw to work with an Extron RGB at all--without using an external LM1881N sync stripper. The gscartsw built in sync stripper doesn't get the job done.jamon1567 wrote: I wanted to make sure because I have this cable that I use with my gscartsw 3.4 to output to my monitor/crosspoint, yet when I tried to connect my crosspoint to the Extron RGB using this, it didn't work.

General notice:
Before the predictable "you've been quoted at schmups" notification arrives, let's establish something: Yes! I tried using the switches on the gscartsw to fix the issue. I noticed there are some labels printed on the board and they tell me what the switches do! Amazing!
All sarcasm aside, it really doesn't work. I didn't bother returning it or complaining. I just added the sync stripper to the chain and moved on.

Re: SCART to D-SUB 15 (DE15) adapter
Oh yea, I understand and I have the same issue. I use the cable for running video from my gscartsw to either a monitor or a crosspoint. I was trying to use it by running my SuperGrafx (which is the system I need to get into the Extron RGB) --> female scart to BNC --> crosspoint --> Extron RGB. However, since the cable is not bi-directional, I couldn't get the signal from my crosspoint to the RGB unit.orange808 wrote: I can't get output from my gscartsw to work with an Extron RGB at all--without using an external LM1881N sync stripper.

Thinking this through a little more though, I'm not sure if I want to get the scart2dvi or the sync strike. I don't need the LPF since I'm using the SSDS3 on my SuperGrafx, so the sync strike would get it done. And the sync strike can be powered by scart, so I may go that direction so I have one less cable (usb to power the scart2dvi) to worry about. Oh, and the sync strike has a case you can buy too, so there's that.

Ah, that's interesting, CRT or a newer technology? Also: is that the only type of sync the pinout would allow? I'm very green (no pun intended) in this regard, my apologies.

Re: SCART to D-SUB 15 (DE15) adapter
Yup, that's the one. There's no good reason why it wouldn't - if it contained circuitry to combine H&V sync it would almost certainly be advertised as a feature and cost a lot more.kitty666cats wrote:You're talkin' the light gray Monoprice, yeah?
