Jacob Proctor aka Tinkerplunk aka Arithmaldor has just released breakout adapters designed for PlayStation and SNES-Style Multi-Out’s. These are handy boards for people who want simultaneous access to all of the signals generated by these consoles. With both boards, you can output Composite, S-Video and RGB (or component if it’s a PS2), all at the same time and it’s perfectly safe for your console.
These are extremely handy tools that I’ve been using in live demo’s at expo’s to demonstrate signal differences. They’re also really handy for technicians that just want a simple way to test all signals when working on a console. The “component video” outputs simply break out the RGB lines to RCA, meaning you can use RCA to BNC cables for use with an RGB monitor, or if you’re using a PS2, simply use them as component video outputs! There are some warnings with these devices, as they’re designed for experts who already understand their purpose:
These boards are NOT converters, simply breakout boards. The dsub VGA-style port is there to allow the use of VGA to BNC cables for RGB monitors, or even the dsub HD15 to SCART adapter Jacob’s also posted, which allows you to use VGA cables to connect these boards to SCART devices.
While there are technically two RGB outputs, you can only use one at a time: dsub or RCA. These were put there for convenience and attempting to use both RGB outputs at the same time will most likely result in the death of your console’s video amplifier!
The dsub connector on the SNES board has a jumper for TTL or 75ohm sync. I suggest leaving it on 75ohm unless you’re sure you need TTL, like with some Extron interfaces.
The dsub connector on the PlayStation board allows you to choose between luma or composite video for sync. You can NOT use the corresponding output at the same time, otherwise you’ll do the same damage as dual RGB!!! Said differently, if you use luma as sync, don’t use S-Video at the same time and if you use composite video as sync, don’t also use the composite output!
Don’t use both audio outputs at the same time, for all the same reasons.
Make sure to set the strain-relief “foot”, otherwise you’ll put too much pressure on the multi-out (see twitter video below).
Don’t let the warnings fool you into thinking this is a “dangerous” device – It’s an extremely handy tool that if used properly can be a giant help for people’s setups. Open-source files are available for all designs on Jacob’s github and they’ll eventually be available for purchase on his site:
Small release thread! Here's some of what I've been working on for the past little bit.
