video switcher control via catalyst

Hey Johnny,

Serial is finicky. If you can get it working reliably in the shop, you're fine. Juts don't expect to be able to change much on show site. You'll end up shooting yourself in the foot if you try to change serial rates, sizes, etc. on show days.

you have to get it working on a site- with the cables you have-
rs232 is NOT electrically robust and electrically isolated - its suceptible to interference and grounding problems.
designed for small cable run in controlled environments.

almost always incorrect cables and incorrect pinouts -

you never change data rates.

I've modified my initial posts to be more informative and address these statements.
