Title: has anyone hooked up an arcade vga to an electrohome g07?
Post by: rob1234 on June 04, 2005, 05:02:29 pm

I have an electrohome g07 that I am trying to hook my arcade vga up to. I am getting a green screen that shifts horrizontally and you can't see anything else. I have the pin out for the chasis, but I don't know which pin is pin #1. Anyhow, if any one here has installed this card with a breakout cable on the monitor please pm me. I need some pics of the breakout cable connection. Otherwise is there anyone here willing to wire this all up for me for a price? Let me know. Rob

what about my plane ticket  ???

anyway, if you have the breakout cable from Andy, it should have a label on it.  R G B Gnd Hsync Vsync.

All you need to do is hook it up to your monitor with the same color. If your not sure which cable is in the breakout cable AKA VGA Cable HACK, get an OHMmeter and check it.

PIN #

1. R = red
2. G = green
3. B = blue
5,6,7,8,10 GROUND
13. H = Horz Sync
14. V = Ver Sync

13/14 might be twisted together to get COMPOSITE signal.

I would ship the chassis...LOL. I do have the cable from ultimarc and it is labeled, I do not know what pins or wires I am supposed to connect it to on the monitor. I thought I had the right series of pins, but it doesn't work.

standard 15kz arcade monitor has only this cable..

 R G B   GND   Hsync   Vsync

sometimes

  R G B    GND   Composit

just wire it up to the right ones :)

if you don't have the cable on your monitor, its labled on board
R G B etc.....

The g07 has the standard video connector.

The 6 pin connections are (from right to left) E1 thru E6


E1---Red
E2---Green
E3---Blue
E4---Ground (connect RGB grounds here)
E5---Pos. V sync
E6---Pos. H sync


J1---Ground
J2---Neg. V sync
J3---Neg. H sync


So for the arcade vga you need e1-e4 rgb-gnd
then j2 and j3.

I had to use separate syncs for the g07 with a arcade vga,
you also might want to look at the sync mod (Some g07 shipped with the wrong components installed on the board.)

Sync Fix

On the monitor board, replace C303 with a 10 uF@50V capacitor with the
positive lead towards the collector of X305.  Then replace C501 with
the capacitor taken from the space C303.


Hope I haven't confused you more.
