Thats the hard part cause you could mess up and screw something up .
So if you have a computer/laptop with a RS 232 port or a USB/RS 232 adaptor you can download the marquee controler program and use that to download your settings and then
do your initialization from the laptop.http://vdcds.com/utilities/Marquee23.zip
That link will download Automatically , once you connect your Marquee to the
laptop you can run the loader program to down load the settings to a file,
or run the controler program and from there you will find a path to save the settings.
The PJ will have a numerical name, since your green is out you wont be able to see it.
but it most likely is 000 or 001. In the controler program it will ass you which PJ you want to control. there you will click the unitilities button and follow the chain/map to initialize. I am not sure exactly where it is in the menu structure but once you connect
you'll be able to play around and should find it.
I use this program for adjusting greyscale and doing other adjustments as it has a finer
resolution for adjustments.
I should make a video tutorial some day for it.
