Question For Dave_K.
« on: April 24, 2005, 01:36:55 pm »
In the next week or so I'm planning on hooking up my Dreamcast inside my Windy cab.  I've read through a few of your posts and saw where you said to use a VGA switchbox (something similar to this, I assume) but just wanted to know which order to plug it in.

Should it go J-PAC to VGA switchbox input, output A to ArcadeVGA and output B to Dreamcast VGA box?

If someone else is running a J-PAC in conjuction with a Dreamcast, then this question is for you, too. ;)

Good question.  I just got a jpac with my astro cab, and tried hooking up the DC-VGA output through it with bad results.  The jpac has an onboard video amp, and the DC-VGA is already amplified, so what you end up with is your screen fading to white as the signal gets overloaded.  Thus you can't switch the jpac's vga input with computer/dreamcast (its not going to work).

The only solution I can think of would have to then be using a switchbox to switch the monitor from Jamma to Dreamcast.  This means creating a custom vga cable for your arcade monitor that goes into the switchbox's single output port, and then run the DC-VGA output to one of the switchboxes inputs.  The other switchbox input would have to connect to your jamma-RGBHV cable.  You'd have to make this custom cable as well.

Ow, my head hurts. ;)

Seriously though, thanks for the reply.  Once I've gotten everything running smooth on the J-PAC side of things I'll try and figure all this out.  Thanks again.
