+5 volt & +12 volt Jamma harness wiring questions
I have a Multi-Williams Jrok board and I'm in the process of wiring the switches and power.
A couple of questions:
1. +5 volt power wiring: Can I connect all 4 leads to the same connector at the power supply? or do I just use #4 one since I have a generic harness? Which one?
2. Ground wiring: 2 sets of 2 at the top of the board. Connect all 4 to the same ground connector? Or just #1 & #2 ones?
3. 12 volt? Not connected since this board is only 5 volts. I'll use that for the LED lighting. No florescent lighting used.
I've attached a pic.
Since I'm going to be using a VGA monitor, it will have it's own power supply.
I've also attached a shot of the wiring for the power supply. Can anyone confirm it's been done correctly?
3. Bottom ground on board #28. Run this to the coin door correct? What about the others?
4. Common ground for all the buttons and joysticks. Daisy chained together and then grounded to the power supply correct?
5. Video Sync. Since I'm running a vga monitor, do I need to use the H-Sync and V-Sync?
This is the part that's confusing me. I've been to the Real Bob Roberts site and it's offered some suggestions as well.
If anyone could send me a pic of their wiring, that would help immensely.
Thanks.
