How do I get the right sync to my guncon2's when using a hantarex polo2 CRT.
The CRT has RGBHV pins. Which signal needs to be presented to the phono connector for the guncon to sync without messing up the CRT display?
Is it only H-sync, V-sync, or both combined to make composite-sync?
And if I combine them, won't that mess up the polo2's sync as it'll then have composite sync to both H and V pins?
Looking at the monitor I might have found a possible answer.
On the polo's input pins,
PIN1 is marked "HS or Comp"
PIN2 is "VS"
PIN3 is GND
PIN4 Red
PIN5 Green
PIN6 Blue
So assuming the guncon wants composite sync, I could join HV+ wires and send them to PIN1, PIN2 is then not connected.
I could then use composite sync to the guncons by taking the signal from PIN1.
Seem about right?
It is right - worked first time, except if I connect both sync+gnd to the guncon, I get no aim.
Connect just the sync, and aim works. Must be some difference between UISB GND and the polo's GND.
Either way I have it working!
