Arcade VGA cable and ground?

[vartech]

I have the Arcade VGA cable and I am trying to wire it using the cable from ultimarc on a Wells-Gardner 25k7193 monitor.  the question is the cable has G R B H V and a bunch of cables wrapped together with a I is this ground? and if so were do I ground it?  also the picture scrolls vertically.  I have changed the pots on the board and finally had to connect the H and V together.  will a video amp take care of allowing me to solve the scrolling and seperate the H and V so I can add a light gun?  

Please help I have three boys who are howding me to play the games i talked about when I was an arcade adict.

Hello vartech.

I'm not familiar with that cable and could not see a description of it on the Ultimarc site but for the connection you should take a look here .. http://link.mywwwserver.com/~jstookey/arcade/WG_25k7191/

That should also answer the question about the light guns (seperate H & V).

Regards to all,

John

I will look at the cables on my monitor it had five cables of a harness that I assumed were R G B Vert and Horz.  Now I wonder if they were R G B Horz and ground.  I will have to double check that.  the cable does not match the discription from Ultimarc because they say it is labeled ground but Mine has an I and it is made up of mutlple cables.  I will check and reply when possible but I am gone for three weeks vacation.  I hope this works my kids are dying to play

No, no, no...

The bunch of wires wired together are the ground.  The lable is not the letter "I", it is a "-" dash symbol.

The H and V are horizontal and vertical synch.  If your monitor is a composite synch, then you combine the V and H wires together and attach them to the monitor.

Check this link:

To quote the web page:

R, G, B = colours
H = horizontal sync. H and V sync can normally be connected together for most monitors to produce composite sync.
V = vertical sync
- = ground
+ = 5 volts. This connection must be insulated if not used.

A side note, I recently purchased my cable and there was no "+" wire.  This was fine because I didn't need it anyway.

I figured the -  was the ground and it uses composite sync but found out here that I can seperate the V and H

The only issue I have now is the vert is scrolling when I switch from mamewah to mame to xp.  I can adjust to stop it but it is still a pain.
