DT30 jumpers "invert image"

[CRFultz]

I finally powered up my galvos, and they work great but the image is upside down.
I'm aware of the two jumpers on each amp that is supposed to invert the image but I don't know what orientation they should be in. It would seem from the spacing of the pins they can either be jumpered or not jumpered. I removed the jumpers but there was no output.
The doc's show the jumpers but it doesn't elaborate on what to do if the image is upside down.
My beam is hitting the Y galvo and bouncing down to the X and then out. It's the only orientation I can use.
Do I need to swap galvo positions? I'm afraid I'll never get them aligned back just right.

Thanks

Swap the jumpers round to the inverted position by lifting the pair off, rotaing them through 90 degrees then plonk em back on - hey presto axis will be flipped

Thanks Rob, thats makes since, the spacing on the 4 pins doesn't make a perfect square, so I wasn't sure.
I'll give it a shot...
Thanks
