Extron Emotia GX Operating Instructions

[Fudoh]

The DSub/HD15 output is a passthrough output. For 15khz RGB you HAVE to use the BNC outputs.

[fagin]

If the lights go crazy on the front, it means it can't latch on to its input signal. As Fudoh says, you need to use the BNC for connection to your JAMMA.

[Beaps]

Ok I will give the BNC a shot, thanks guys.

[antron]

but that shouldn't be why the lights go crazy, unless tying the syncs together at the VGA out messes with the VGA in.

maybe try unplugging the VGA out first to see if the Extron will stop flashing.

[Fudoh]

that's likely a problem with the 360 defaulting to some stupid 16:9 VGA resolution when set to VGA. He needs to connect it to a monitor through VGA first, make sure it's set to 4:3 and 640x480 and then it should be fine.

[antron]

he did, previous page.

[fagin]

Beaps has already confirmed that the 360 was set to 640x480 via VGA.

[Beaps]

but that shouldn't be why the lights go crazy, unless tying the syncs together at the VGA out messes with the VGA in.

Lights only go crazy when I connect the VGA out and switch on the cab. Before I switch on the cab I have the one nice solid input light

[antron]

that's it then. using BNC should work.

[fagin]

Mashing H&V together on the "monitor out" won't help...... you're lucky you haven't damaged it with some form of back feeding. That is very bad practice imo.

[Beaps]

I hope I haven't

I will try the BNC route and report back, cheers guys

[Beaps]

Monitor survived the tinkering

OK BNC's in place to Jamma Edge connector, I left on the ground to video sync wire and......

Greeted by this lovely screen

[Beaps]

Been messing with this all night, I give up. If it was a women I would of tried every position in the karma sutra

[antron]

I left on the ground to video sync wire and......

what? this reads like you have grounded video sync.

[Beaps]

If you look at the very first thread it says run a wire from pin 1 to video ground, which I did. With it connected or not I still get the same picture.

[Fudoh]

It seems more a problem of the connections between the Emotia and the connector you use to connect your monitor to. Did you connect all four grounds (R/G/B/Sync) on both ends (Emotia and the other end of the cable) ? Also try to flip the terminations switch on the back of the Emotia.

I would take the Emotia out of the cab for moment and check if the composite and/or s-video outputs on the Emotia work fine on a regular TV set. After that take it back to the cab...

[Beaps]

Silly question...

On the BNC cables, I connected the signal to say red. The outer shielding (the cable grounding I think) is doing nothing. Am I supposed to connect to something?

[Fudoh]

yes, to ground. On all four BNC ports. You can connect all four of them to the same ground line on the other side (as long as you're sure it's really wired to ground somewhere)

[Beaps]

Ok let me try that buddy

[Beaps]

Ok so I wired up all the BNC grounds to video ground. It's getting there but the image ain't quite right and very dark. Am I supposed to connect a wire from video ground to jamma pin 1 ground?

[Fudoh]

zero experience with jamma looms, so somebody else will have to chime in.

[antron]

Was your E2 being used with PCBs before this? Non arcade RGB video levels are different, and some arcade monitors don't compensate for the difference.

[fagin]

We have some fundamental understanding issues here.


Beaps - step away from the soldering iron and think about this logically.

What you're trying to do is very very easy and you're not looking to re-invent the wheel..... well, not this week.


All your fingerboard needs (from the Extron) is R, G, B, Gnd and Sync, to get a signal to push through to your monitor. It is that simple...... so if it's not working, something fundamental must be wrong.


1) Whilst your XBOX is connected to the Extron, you should have LED 3 lit only on the front of your Extron - Check?

2) The output from your Extron needs to utilise the R, G, B & S BNC's - Check?

3) Centre of R BNC should go to PIN 12 parts side on JAMMA edge connector - Check?

4) Centre of G BNC should go to PIN 12 solder side on JAMMA edge connector - Check?

5) Centre of B BNC should go to PIN 13 parts side on JAMMA edge connector - Check?

6) Centre of S BNC should go to PIN 13 solder side on JAMMA edge connector - Check?

7) Take ALL (just to be safe) Grounds from each of your R,G,B & S BNC's to PIN 14 parts side on JAMMA edge connector - Check?

Remove ALL other wiring from the JAMMA edge that are not stated above - Check?

Let me know what you get when you go through this.

[Beaps]

That's what stage I am at Fagin. The only thing I missed was connecting up the BNC grounds which in my last post I said I have now done.

The picture still looks crap. When the 360 starts say, the green Xbox startup screen say, looks illiminus green. (where all the swirls make the Logo)

Don't get me wrong guys although I am new at this I can follow simple guides and solder skills are pretty good

[fagin]

So all the above steps are checked as per above?

What else have you got connected to your fingerboard?

Assuming the first answer is Yes and the second answer is Nothing:

1) remove all grounds to PIN 14 and only reconnect Sync ground from Extron to PIN 14. What happens?

2) press the voltage push button on the back of the Extron. What happens?

[Beaps]

Ok so all grounds removed apart from sync and it's the same image. Pressing the button on the back is difference between crap screen and blank screen

[fagin]

OK - I knew the voltage switch would not do anything as your problem is not RGB line voltage related - just wanted to be double sure though.


What change (does it alter the image) in image do you get if you remove the ground completely?

[fagin]

Ok so all grounds removed apart from sync and it's the same image. Pressing the button on the back is difference between crap screen and blank screen

Also.... it's important you read what I'm asking and answer in full mate. There are the initial two questions I asked above, that you haven't reconfirmed (So all the above steps are checked as per above? & What else have you got connected to your fingerboard?). Humour me even if your answer is obvious.

[Beaps]

I currently have this only connected to the fingerboard

r,g,b,s = all signals in place

The ground from the bnc sync only, wired to pin 14 only. Nothing else is connected to the fingerboard.

[fagin]

What change (does it alter the image) in image do you get if you remove the ground completely?
