In case anyone out there is searching for information on upgrading their own monitor on a Pac - let me compile the info I found in one place.
(What I personally did was switch out the old 19" RCA monitor in a Ms. Pac with a 19" shelf-mount Vision Pro from Happ. The Vision Pro is rebranded in at least one other place, but with Happ's frequent sale price ($135) this was a good deal.)
The monitor showed up three days after I ordered it. I opened it up, and noticed that the connectors/wires coming
out of the Vision Pro were as follows:
- 1 AC power cord for the monitor. You could plug this directly into the wall.
- 1 set of wires for such things as red, gree, blue, gnd, vertical sync, horizontal sync
- 1 little "board" that has knobs to adjust screen position, brightness and contrast, coming from the monitor. Some new monitors make this a remote control, but on the Vision Pro it was connected by wires to the monitor's board.
The old monitor got power from the Pac's power supply. It had two wires (black and white) - the AC power cord on the new monitor had three, as a green ground wire was included. Since I plugged the AC line directly into the wall (didn't want to cut anything on the new monitor in case there was a problem) I have the existing monitor plug just sitting in the cab. That reminds me, I should probably put some electrical tape over it, because it's otherwise active. I could have sent that green wire on the new monitor to ground elsewhere. and fed the black and white wires into the Pac itself. I guess a lot of people do that.
Okay, that leaves us with getting color and sync to the monitor. I am going to paste a reply I got from Gunbu on the KLOV forum.
Here goes the wiring:
First, clip off those old video connectors on the pac wiring harness. There should be one with 4 wires. And one with two. (NOTE: mine had three. -- ICJ )
Ok, here are the wire colors. They may be different on your harness, so I'll also give the pin location.
The four wire connector:
Video Ground: Green-Red ( color wire )Pin S ( wire location on the harness )
Video Red: Red-White Pin T
Video Blue: Yellow-Black Pin U
Video Green: White-brown Pin 16
The two pin connector:
Video Sync: Orange-red Pin 17
On the two pin connector, you will only need ONE of those wires. Doesn't matter which one, they both come from the same pin location.
Ok, now you're ready to start connecting those wires!
The Happ monitor comes with a new video harness, so you'll need to connect the wires to it.
Connect:
Video Red to the red wire
Video Green to the green wire
Video Blue to the blue wire
Video Ground to the black wire
Video Sync the yellow wire
The last white wire on the happ harness is not used.
Ok, got all those in?
Now, the power to the monitor.
Connecting the power is easy, the old pac monitor ac cable plugs right into the Happ cable. The Brown wire on the Pac harness side of the ac cable is the hot side. On the Happ connector, the neutral wire has the round end, and the positive one looks like a D. Slap those guys together, and you're ready to go! You'll probably have to mess around with those dials on the monitor for a while to get the picture to stop rolling/ centered.
Good luck!
And this was what I saw as well. The white wire coming from the Vision Pro was not used. For synch, I had three orange wires that were on their own molex connector - those three wires rolled back into a single wire that went to the Pac's PCB. Like so:
Now, the wires for color and sync on the Vision Pro
do not have a molex connector. What I did was just shove them into the female end on the Pac, and then used electrical tape to hold them in place. This oughta be fine - a lot of guys have extra molex connectors around, so they can build their own.
At any rate! This should hopefully help out any newbie, like myself, trying to do this sort of thing. The part where I really struggled was in getting the old monitor off and the new one in: apparently, I could have removed the entire shelf. I only removed the monitor itself. I had to have the thing on its side, so I wasn't fighting gravity. Oh well, live and learn.
