    25-pin D-sub, SCART, and other shit

    Hey kids. I'm getting a rather cheap 25" Multisynch professional monitor. It'll probably turn out to be an interim until I can get a more long-term TV with SCART input (a real chore to do here). Anyways, it says it's got the following inputs I'm curious about:

    1: RGB
    2: D-sub 25-pin

    Here's a pic
    [​IMG]

    Their version of RGB seems to be the input labelled VTR... seems non-standard and goofy to me. The other one is the 25-pin D-sub. Will a D-sub 9 pin -> D-sub 25-pin work? I'm looking to make this an emulation machine (IE -- with a low-res arcade card). Just wondering if it'll work.

    The ideal machine would have 2 Scart inputs, as there's a mod for the card I'm buying... just not sure what the hell that other input is.

    The VTR thing is for digtal RGB, the normal analog RGB is input on the DB25. I've looked very hard before for a pinout on Sony's DB25 but I never found one. I don't think a DB9 -> 25 adapter will work because those are generally used for adapting serial ports right? Chances are Sony didn't arrange the pins so that people could use a DB9 adapter :) If anything, perhaps the monitor follows Amiga's pinout.

    I'm not sure if you're going to be able to use the PVM as a VGA monitor, if it accepts seperate horizontal and verticle syncs then I don't see why it wouldn't but I know for sure that PVM takes composite sync. So.. that means you'll need a card that outputs composite sync and you'd have to be sure that the monitor supports 33.1KHz, I don't think all PVM do.

    Well, that sucks. :(

    Any links to a reliable place that sell TV's w/ Scart inputs? (Preferably in the US?) I want to avoid arcade monitors at the moment.

    That monitor would be great for console games/supergunning, I wouldn't give up hope. It's just likely going to take more time and money than you expected. The only real hardship would be tracking down the pinout, maybe you could get it from Sony themselves. If you REALLY wanted to use the monitor with emulators, Ultimarc sells an "arcade" videocard that surely outputs 15Khz composite sync. I think it costs like $90 though... http://www.ultimarc.com/ If I were you, I'd get that videocard and a J-Pac, then you can get your MAME on through your Sigma ;) Also, don't forget that you could make/have made a SCART -> Sony DB25 adapter.

    I was planning on buying that card... I just don't know if I can use it with that monitor, that's all. :(

    I've kind of got this wild hair that I REALLY want to try RGB. The Sigma has RGB connections (just gotta buy 'em) and there's even an RGB cable for the Saturn.

    I'm looking at this TV. It seems like a fair price, and shipping is only like $120 bucks to Hawaii. It's got two Scart inputs, so I could essentially have one open for the computer, and one for consoles.

    You can use it with that monitor but you'll need to do some research. The SCART TV looks good but there might be a 110-220v version.

    I think there's only only 220v...at least the one their selling. I'd need to buy a step down, or of course, blow something up (maybe me). At least I'd have something to put in the "Are CRT's dangerous" thread. Anyways, I'm getting the PVM pretty cheap. It'll hold me for a while. The wife wants a TV in the bedroom pronto. NO... not b/c there's no action there, but b/c the living room is too hot she says. (sheesh).

    I guess I"ll look around for the pinout...wouldn't know where to begin (other than google though).

    Isn't it mandatory by law, or something, to give out pinouts to consumers? I'm not sure why that would be, but there's a surprising amount of pin definitions in (my) electronics manuals, for no apparent reason (why the hell would Joe Blow need the pinout and baud rate to the CD-i's controller port?)

    Yeah, the manual would have said the pinouts (well over here anyway, TV/VCR/DVD player manuals always list all the SCART pinouts), but I take it you don't have the manual. Anyway, the pinouts on the sci.electronics.repair FAQ are probably right enough.

    Anyway, what exactly are you trying to put into it? It seems it'll only take 15kHz signals, but fortunately it appears to take both composite sync and H/V sync, so if you're planning on doing some funky stuff with a PC it shouldn't be a problem... as long as it's 15kHz...

    Basically, it can do everything SCART can do (except for auto-switching and stuff), *AND* H/V sync!

    Am I right to believe standard res. arcade systems all output composite sync., or do some do H/V sync?

    And about that Sony Wega - it's definately a European model so there's no chance you'll find a 110V version. You'd want a pretty good step-down transformer - one that can take 150 or 200W or whatever power the TV needs - smaller ones you use with consoles or whatever will blow... or melt...

    Be warned though, I heard with some Vegas that 60Hz signals (i.e. not 50Hz PAL) look kinda shitty. I don't know about all of them though - ask around or something. Since you'll be using it strictly for 60Hz, you may be better off with a similar Panasonic model or some other decent brand. And Sony tend to be a bit skimpy on inputs - similar size PAL TVs from other brands often have 3 SCART sockets, s-video mini-DINs and sometimes even component YPbPr RCA jacks. Most PAL TVs these days can take proper NTSC composite and s-video signals, but not *all* of them. Though I'm pretty sure all new Panasonics and Sonys do.

    Hmm, if I remember right my friend has a Wega and 60hz through S-video looked like cack (way too bright, also).... but who needs S-video when you have scart :D

    Thanks for the input guys. The problem is, after searching Google for "Multisystem TVs",, "TVs wth Scart", "blah blah blah" I only get a few Sony models, and only one of them is 50 Hz. I heard that most European TVs have Scart, but that doesn't seem the case if you sample the ones you find in import electronic sites in the states. Go to this page and search for 'scart'. You'll see what I mean. I would personally rather get something other than a Wega... just can't seem to find it.

    The signal that would be coming out of the PC would indeed be 15 kHz. Check the link that Kyuusaku posted. It's a low-res card... basically outputs true low res, but you gotta have a monitor that it'll work on. It would be nice to have Scart for consoles, but for the time being, and for the relatively cheap price I'm getting it at, I won't bitch.

    If you look at the first link I posted, apparently there are no VGA to 21-pin RGB cables floating about apparently. I just find it weird for Sony to make it in the first place but for it to have basically no standard connector. :/ I guess you'd have to make one, and I suck shit at that type of stuff. If anyone can point me to a place that has a nice TV with multiple scart inputs and is in the US, I'd be forever in your debt.

    I think there's some experts on the subject floating around gamesx's forum.

    Probably not a bad place to look. I'll check it out.

    Have you considered using a transcoder (RGB -> component)? I think the XSelect-D4 is the most elegant (affordible) solution other than using a PVM or similar RGB monitor. In that case, you'd need to adapt whatever ArcadeVGA outputs to the Japanese 21pin SCART-like connector or you could simply buy the RGB cable for your Sigma and get ArcadeVGA & J-Pac, that'd be a fun experience ;)

    I'd like to discourage you from importing a Euro TV. Do you have some specific must-haves for your monitor? There recently was a beautiful new Sony GVM-2020 on eBay for under $600 shipped in the US, that should also be safe to tip on it's side ;)

    Well, the ideal TV/monitor that would make me bust a nut would be

    -25"-28". I'm actually impartial, but that's the ideal range.
    -2 Scart inputs -- these are the most important. There's an easy mod for the J-Pac to go VGA->Scart, there's a Saturn SCART cable, and the Sigma has one as well.
    -Doesn't look like shit. :)

    I would really be happy if I could make this D-sub RGB work, but that looks like it's going to take a skillset I don't have. Actually the guy I'm buying from is a poster on Shmups, and is buddies with one of the rather skilled Control Box (I know you hate the word SuperGun) makers on the board. I think he has one of the monitors as well, so perhaps he can shed a little light.

    It doesn't look that hard to do - if you can find a suitable plug that is.

    As people said before, VGA to SCART isn't easy - you'd need a circuit to convert the H and V sync to composite sync. With the TV you have now you won't have to do that.

    *ALL* new European CRT TVs over 10" or whatever have at least one SCART socket - it's mandatory now, and it's been like this since at least 1997. Even the cheapest Chinese pieces of shit have them now - the ones you'd be lucky if you get a remote control with! Those shops could be importing their stuff from Australia or somewhere else. Nearly everything from 20" has 2 sockets now as well.

    Though there is the problem that there isn't really much of a selection of 4:3 PAL TVs over 21" any more... OK, actually it seems to be just the British Isles that they're giving shit selections. I looked at Panasonic's UK site - just one crappy non-flatscreen 28" 4:3, and looked at Sony's UK and Irish sites and there were no TVs over 21" that weren't widescreens. Then I looked at their German sites and Sony have two 29" and one 25" sets, and Panasonic have two 28"s, two 29"s and even a 100Hz 29"!

    Finding that plug is apparently a trick. There's actually a local guy who's a lot more HW-oriented than I am that might be able to cook up something. I'll see what he says.

    I couldn't imagine these shops importing from Australia. It would seem to me the freight costs would be WAY more. I guess the slow way of going about it is checking the specs at the manufacturer's website.

    I'm sure VGA to Scart isn't easy, but I know someone that's done it w/ his, so I could either get instructions or perhaps bribe him to make me one. I suck at electronics, but I'm not bad at following instructions. I'm still debating buying that 50hz Wega. I should probably read up a bit on it first. Either way, I'll fuck w/ this Sony monitor first.

    Do you really want SCART or Japanese 21pin connector? The Japanese one isn't SCART although it shares the same connector.

    Found some noted on my PC and the Sony 25 Pin Outs are...

    1 - Not used (unless you really want to use CGA / EGA or TTL RGB)
    2 - Audio Select (Low - Audio Input from Line A, B or VTR jacks; High - Audio input from Pin 13)
    3 - H Sync or C Sync (Negative Polarity as SCART)
    4 - Blue
    5 - Green (also supports Sync on Green)
    6 - Red
    7 - NC
    8 - NC
    9 - Must be tied High (5V) to select Analog RGB mode
    10 - Must be tied High for RGB mode
    11 - V Sync (not used if C Sync is used)
    12 - Blanking (High - RGB only, Low - Input from A, B or VTR jacks will be superimposed)
    13 - Audio Input
    14 - NC
    15 to 24 - Ground
    25 - Not used for Analog RGB mode

    The device you have must supply 5V or you won't be able to use this port. Use a 75Ohm resister in series with the 5V line. Tie anything you need low to Ground.

    Hope that helps... :p


    Other notes H / V Sync (as long as they are negative and within 15Khz ranges) with two 500 Ohm Resisters can be tied together to get C-Sync.
