Hi! I recently bought a Wells D9500 from another KLOVer for my APB.

Here's the schematic: https://www.wellsgardner.com/wp-content/uploads/2016/08/D9500-1.pdf

It's a Tri-Sync monitor, and has several inputs.

The pinout for the P001 "traditional" 10-pin connector is the typical monitor pinout but the schematic has this little note regarding a jumper block right behind that connector (which you can see in the schematic):

Never had to take note of the voltage levels for an arcade video signal. I've been reading that arcade signals are generally 2-5V, so should I configure these jumpers for the 2.2Vpp? They are set for the 1.4Vpp level now, and the seller demonstrated the monitor working fine with a standard arcade PCB, and seemed to work fine.

Is there any danger is damaging the chassis if I have these jumpers wrong? It looks like the jumpers just select a resistor which I'm guessing is to normalize the signal level to whatever the monitor prefers.

Appreciate any insight here! I don't mind trying different settings, but I don't want to risk damaging this monitor!
