Just tested daisy chaining - works perfectly for me. Only one switch needs external power connection - the other is powered through it as well. At this point I only need LM1881 turned on for: Jaguar Neo Geo Omega CMVS Sega Saturn No LM1881 needed for: Genesis/SCD/32x N64 NESRGB PS1 3DO SNES Dreamcast PC Engine DUO R
interesting that I need it turned on for different consoles. is your sync level set to 9 (mine is) still or have you changed it? I dont need it for my Saturn (looks like yours is a model 1 like mine), but do for the doujindance modded Duo-R modded. The Duo-R was the only one I needed to use it with when I stopped using the external supply (not counting the Nintendo consoles with c-sync).
Yeah, I use sync level 9. For the Saturn, I am using retro_console_accessories cable (eBay seller). Without LM1881 there are some problems with the sync but they are very minor and not frequent. My Nintendo consoles are all using CSYNC from pin 3 on the av multiout, wired to composite video on the scart end. For the Duo-R I am using the cable that doujindance provided with the console (its also svideo modded).
I'm using the same cables as you for the saturn and duo-r. Don't know why I cannot get csync on the snes and n64 to work on mine if it works on yours without the sync stripped. Not really a big deal as everything works with it on. Just don't know why it would be different. I'm most likely just going to leave the LM1881 switch set to on all the time. I can see why we never got RGB scart here in the states. The average American consumer trying to figure stuff like is out would never work. It most likely would have been a nightmare.
Are you sure you have CSYNC routed to pin 3 of the AV Multiout? Which version of the SNES? Does your cable in turn have pin 3 routed to composite video?
Yeah. My snes mini and one n64 both have switches that route the csync to the composite video pin on the multiout so can use a normal cable. The other n64 I connected csync to pin 3 (original snes is already like this) and I tried a "raw" sync cable that I use for csync on my NES on those. Csync works on all of them but the lm1881 needs to be on. Which doesn't make sense really as they are already "stripped".
All NTSC SNES have csync available. The original models already have it on the multiout. The SNES mini has it, but it needs to be connected to the multiout. My consoles are all fine using csync directly to the xrgb-mini so my consoles are not the issue., Its just when you add the switch in, they need to have the LM1881 powered on to work. The N64s and SNES mini get no picture, and the regular SNES gets an unstable picture without it on. But its not a big deal, was just curious as to why it works on airs's setup and not mine
With the LM1881 switched on. Both with external power supply and without it is the same. I quit using the external power supply as it was causing some interference in my picture though. The only console that I had to mess with was my Dreamcast (Kenzei didn't have voltage on scart pin 8 so I wired 5v to it) to get it to work with the switch without the external power supply.
Sorry, meant on the cable side of things. Cable makers usually build them with composite video hooked up rather than CSYNC unless you ask them.
Cables are SNES cables from retro_console_accessories on ebay. I have the "raw" sync cabel labeled and I know she wired it correctly. Maybe once superg gets more of these out in the wild, he will get more data back as to why they work different for some people. Not really sure what the difference between our setups is. Im just keeping the LM1881 on all the time now as everything works flawlessly in that position.
Yep, I have the same cable. Though I don't need the LM1881 turned on to get video on my SNES Jr. Very strange.
It works fine if I use my compsoite video sync cable without the LM1881. I bought the console already modded so its possible the csync is wired differently in mine. It looks like there are a couple different ways to do it from that link airs posted. Doesn't really explain my 2 n64s though, but its not a big deal.
Hey, I thought I would ask here as I'm more likely to get an answer from people who would know... What kind of wire should I use if I want to make my own Scart cables, does it have to be 75 ohm? Can I buy a bunch of VGA cables and chop them up? Does the impedence of the wire itself not matter only the end connector? Whats confusing me is that you can buy 75ohm BNC and 50 ohm BNC, but something like a 8 pin din doesn't have a stated impedence. Also in any consoles scart connector that I've seen, even official ones like Dreamcast or Wii, the cables don't look like coaxial. Could I use Cat5e?
I don't know much about BNC, but usually wire has impedance close to 0 and you put 75Ohm resistor there. For my switches I am using hi-quality shielded 8-wire from here: http://www.ebay.com/itm/110881442615?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649.
Guys, I just bought SNES Jr and RGB-capable Nintendo 64, I am curious how it will perform with composite sync and csync.
Cool. Will be interesting to see how it works for you. So far it seems like i'm the only one who's setup its acting strange on.
