DB25 Printer/Data Switch -- Can I use an automatic switching one?
« on: January 09, 2005, 08:13:40 pm »
I'm about to hookup a Dreamcast to my arcade cabinet alongside my existing IPAC/2 and I know I need to use a DB25 A/B switch.  What I'm wondering though is if I can use any of those "automatic" printer switches or will that not work properly?

I do not think an automatic one would work in this case.  The reason being, is that the "automatic" circuitry looks for printer in use commands, probably on certain centronics parallel data lines.

You may be able to use a MANUAL DB-25 data switch, provided that all 25 lines get switched, and the matching internally is 1-1.
