Title: Ultimarc JPac jumper question
Post by: Unholyknight on March 08, 2007, 12:34:44 am
I got my JPac in today and its fantastic!  The video quality is amazing compared to the old adapter I was using.

The problem is that Andy forgot to include the other 2 jumpers that allow you to select the control interface.

On the right side of the board there are 4 jumpers, 2 on the monitor Hz selections, and also 2 on the control type selection.  It only came with the 2 on the monitor Hz selection jumpers, so I'm sitting with an awesome display and no way to tell the JPac what kind of control interface I am using.  The JPac, when running on an arcade monitor, can work without the Hz jumpers attached, but with them taken off there is a slight annoying interference on the screen, thats why I would like separate control jumpers.

Does anyone know exactly what size jumpers those are and who sells them?  I'm guessing that radio shack has jumpers, but that leaves me with the initial size question again.

They are standard. radio shack will have them. or you can scavenge them from old pc hardware (hard drives,cdroms,old network cards etc.)

if you dont happen to have any hanging around and are impatient about getting some, a carfully bent staple will do the trick nicely. Just make sure its tight against the pins and has zero chance of touching anything else on the board.

Didn't think of old PC hardware, I have tons of old Disk drives laying around, I'll see what I have to work with.

I know a lot about hardware, I just didn't know if jumpers were a universal size or if they varied, thanks for the response!

There are no jumpers on the J-PAC for the control interface. I think an email is necessary here to clear this up!
