Many people are starting to use the OSSC Upscaler due to its claimed non-existent lag (its pretty amazing, and I can't see any lag side by side with my PVM. As a new user of the OSSC myself I wanted to give it a whirl with the ADCAP SuperGun but couldn't easily without making some sort of SCART cable. Let me be up front... I am not a SCART guru; all of my RGB experience and usage comes from Arcade Boards and arcade monitors or PVMs that use BNC style connectors. So, I figured I would give it a whirl and find the path of absolute LEAST resistance because I really dislike doing work someone else has already done. Here's what I did...
I found Retro Gaming Cables through mutual interweb friends that highly recommended them. After spending about 2 minutes on their site, I knew I was in the right spot. I quickly found their EuroSCART to Framemeister adapter and thought "BINGO... easy day." I got it in, hooked it up to my SCART to BNC cable I purchased through them, hooked my SCART cable up between the two... and the picture was crap. Nothing was syncing and the audio was inaudible.
Not deterred because "I can fix anything, right?" I did some more research and realized that SCART was a dual path protocol meaning the cables have both "in and out" all in one so you can daisy chain stuff together easily without a huge rats nest of wires. I did a quick google search and found the following image:
I cracked open my adapter cable and sure enough it was wired for input, which makes a heck of a lot of sense given its an INPUT adapter for the Framemeister XRGB-Mini. So, I simply used my soldering iron and removed pin 20's wire and moved it to pin 19 shifting the sync from an input to an output. Tested it out... BINGO! The video was glorious and worked like a champ.
Next I moved pin 2 to pin 1 so that the "RIGHT AUDIO" was in the correct spot and then moved pin 6 to pin 3 so that "LEFT AUDIO" was in the correct spot and we were in business all around. It took about 5 minutes total to do and was well worth the effort because building a cable from scratch can suck. Now, if you do want to build one yourself here's what you will need:
Just wire it all up according to the pin out above and below, and you will be good to go! Here's some notes: Connect pin 4 on the ADCAP output (GND) to every Audio/Video/Sync GND on the SCART connector using a daisy chain as well as the shield from the mini-din cable to the ground chain and pin 21 on the SCART cable. Enjoy!
