Question about Ultimatemister's passive Y/C adapter

Unread post by Allejo »

Does anyone know what does the two switches on the passive Y/C adapter sold by Ultimatemister.com do? I'm creating a 3D printable case for it that I plan to make available for free, so I need to know what to write beside each of the case's opening :)

From https://docs.google.com/document/d/1Frf ... s57drfyfev, it looks like the top one is "DV_ENABLE", or direct video jumper, and the bottom is "NO_YTRAP", or enable/disable luma trap jumper.

One bypasses the Luma trap and you want bypass it for svideo, the other is to use the onboard sync circuit. I would enabled both for composite and enable the sync circuit for svideo.

Don't use the sync on green on the analog io board, it's typically way out of spec.
