New Sync Strike - Available Now!

[lettuce]

Mmmm.... you would need to find out if your monitor accepts composite sync. That loom is RGBHV but that doesn't mean it can't take RGBc.

The SS does not output a proper RGBHV signal.

from the description....

"uses both inputs for synch (horizontal and vertical) - as most games are jamma connector compatible, and have therefore only one synch output, which is composite synch - the composite synch is connected to both inputs and the on-board circuitry will separate the signals."

NPUT SIGNALS:
1. Input connector: 0.156 center header
2. Video type: RGB analog
3. Video input impedance: 1K Ohm; other values available
4. Video level: 1.5 to 4 vlots peak-to-peak; other levels optional
5. Sync type: TTL sync; separate or composite, negative or positive
6. Sync input impedance: 4.7 Ohms
7. Horizontal sync frequency: 15K(CGA)
8. Vertical sync frequency: 47 to 63 Hz

Cool - it's JAMMA compatible so you're rocking mate!

Cool. So rather an me butchering this cable, is there an adaptor fitting you can get so either a VGA plug can be added or just with bare wires the other end so i could connect it up to the sync strike for instance?

BTW whats the correct name given to that video harness?

[fagin]

Christ knows - never seen that type of harness before.

So ill have feck all chance of finding an female plug to fit it then?....i guess ill just chop the plug off and attach to the screw terminals on the sync strike?

[fagin]

i guess ill just chop the plug off and attach to the screw terminals on the sync strike?

Either that or bang a DSUB15 on it and wire for a VGA pinout.

Sounds like a plan, im not sure if im going to have to amplify the signal though, any ideas if the Sync Strike amps the signal if using the screw terminals?

[fagin]

No amp afaik.

[lettuce]

No amp afaik.

Ok, ill have to wire it up and see if the picture is bright enough, otherwise Ultimarc do a VGA cable....http://www.ultimarc.com/JShopServer/sec ... currency=4

Have noticed that this harness that comes with the monitor has the H&V sync connected to the same pin, so i take it i connect this pin to the 'C' screw terminal on the Sync Strike? Also the harness has a black ground wire (well i guess thats what it is) but there is not screw terminal on the sync strike for ground, any suggestions what to do with the ground?

Why do you think you need an amp? Do the consoles work fine at the moment?

Re-read your own re-quote from the top of this page, with regard to the H&V and why they go to the same pin.

You have a ground on the PSU in on the SS.

Yeah i asked a stupid question, in my defense it was late .

I havent tried the console yet, i have heard reports with CGA Hantarex monitors the display was dark when using with a PC, but this might be releated to the using the ArcadeVGA card though. Ill try it and see what happens

So in regards to this, as my vidoe harness for my monitor has the H&V sync connected to the same pin can i just connect the one wire to this pin and run it to 'C Sync' on the SS or do i have to run 2 wires from this pin and connect to 'H sync' & 'V Sync'?, for play my SNES on the monitor??. Im guessing its the first option but just want to make sure as ive been told only JAP-NTSC SNES's do C Sync??

[fagin]

I think just the one wire will do.

JAP SNES only doing CSYNC is irrelevant now - that's why you're using the SS.

Ok just tried my snes on the Pentranic chassis, and guess what im getting the dreeded rolling screen, ive tried altering the V & H Hold and whilst it make it better its still rolling, is this to do with me using the C Sync terminal on the SS instead of V or H sync or both? Heres the video harness i have....

[fagin]

Use H & V sync from the sync strike, although I fear this won't work for what I have said on your other thread.

So im going to have to unsolder 1 of the sync wires that is connected on the end of the plug and solder it to the pin beside it? Question now is how am i going to identify which is H and which is V. What device do you use to play your SNES on your cab?

I heard some reports that you can get away with just attaching to H sync and not V sync is this true?

[lettuce]

Well i have just tried my PS1 console and that has a rolling display aswell so maybe its not the SNES at fault!?, im still using C sync input on the SS however. Can i connect this 1 wire up the the H Sync input or am i going to have to unsolder one of the 2 sync wires that is attached to the same pin on my video harness and separate the V&H sync?

[fagin]

I could of told you it wasn't your actual SNES itself!!!!

I can't see you removing one of the loom syncs making any difference whatsoever. The fact the loom is wired the way it is, you would have to assume it takes a composite sync - it's a shame the manual diagram doesn't say that!

Well this is a bit of info i can find on the chassis...

"The CH-288 uses both inputs for sync (horizontal and vertical) - as most games are jamma connector compatible, and have therefore only one sync output, which is composite sync - the composite sync is connected to both inputs and the on-board circuitry will separate the signals."

The H&V sync's are separate on the plug that plugs into the chassis PCB they just go to the one pin on the connector. So if it does take composite sync is there a simple way i can get a display work on my Pentranic monitor?, i would have though the SS would have been plug and play and thought that was the whole idea behind it?

[fagin]

It is plug and play for providing a CSYNC signal - but whatever your chassis is or is not doing, I'd suggest it's not a problem of the CSYNC signal from the SS.

The easiest way to test any such principal, would be to build your own LM1881 circuit. But I can tell you I get no problem using my SS with my arcade monitors, amongst a whole raft of other things.

Seems strange thought that i was getting a similar problem of my Hantarex monitor and now im getting the same on this Pentranic chassis.

Is there a guide anywhere on building a simple sync strike circuit, i dont want to butcher my snes scart lead, so guess ill need a pcb scart socket (to plug my snes scart lead into) and just screw terminal block to attach the wires from my video harness

[lettuce]

Ok ive got both the SNES and PS1 to work now, instead of connection up to C sync i connect to H sync on the SS and now i get a nice stable picture. Can anyone explain why this works?

[fagin]

CSYNC normally uses HSYNC on a device with a H&V sync output or input. I've never used the breakout connectors myself, so can't comment why HSYNC works over the CSYNC output in your scenario - and that maybe the factor.

[hanibal2k]

Hi all, has anyone tested it with a NES or Famicom connected via SCART? (but with no RGB mod, just outputting composite)

Thanks!

So we all sorted now then?

[emphatic]

Can the sync strike be used between a JAMMA harness (using the screw connectors) and the cgi2vga scaler for a supergun? I wired my JAMMA video straight to my cga2vga but I get an ugly rolling line on screen that I would love to get rid of. Will getting a sync strike fix that? I tested with Ibara PCB on my Panasonic plasma...

JAMMA should be composite sync already... i.e. should feed straight to the cga2vga. Have you tried any other PCB's? Is it only Ibara?

Hi everyone,

I've been using my Sync Strike + Scaler + SG3000 with great success with a Saturn and a Mega Drive 2, both Japanese...

Then I bought a PAL MD1 a few weeks ago (High-Definition Graphics version) and it didn't work properly. The ad for the console said it wasn't tested, so I blamed the console and bought a 2nd one. I tried again with the second PAL MD1 and yep, it wasn't the console's fault!

Yesterday I got home a PAL PS2 and I got the exact same symptoms as with my PAL MD1. My PAL-50Hz consoles don't seem to work properly with the setup:

1- Audio is fine, you can hear perfectly the game.

2- Screen is mostly black, with some artifacts.


3- Top 5% of screen shows the game in motion as it should (at least with PS2):


4- When I try to change the scaler mode (RGBH, YCBCR...) or its resolution, the screen refreshes for a second and leaves a ghost of what the console was outputting when I made the change:


(you can actually see the top 5% still moving, but the rest of the screen is still)

My setup (I live in Canada, so TV is NTSC -which shouldn't matter anyway, as I'm using the VGA input)
- Toshiba 32'"
- Scart cables for all consoles
- Sync Strike + Scaler + SG3000
- Japanese consoles work fine
- Pal consoles don't work properly

I'm afraid I just have basic knowledge about image syncs (raws? pures? no idea...) but it seems the problem has to do with the sync, or the 50Hz output of my PAL consoles, but they should work, as many people in the Internet using the Sync Strike have them working just fine!

Thank you very much for your help, I'm dying to be able to play with my PAL consoles again after so much time!!!
