My Rosen monitor in the Marathon is going out. I bought a new monitor but the original Rosen was modified with connections from the "screen"
button to the old monitor- maybe up down buttons.anyone know how to modify so the tank levels, voltage etc can be displayed?
John,
Doesn't the screens button toggle with each push of the button to the next TechLink screen?
yes it does but somehow that button is wired to the display that is not a stock display. four wires go to the display connecting at the pads for up, down, and I forget the other two. Also want to replace the old computer with the floppy drive. Understand Marathon has developed a rasberry pi to run that system. wonder if anyone on the board has replaced the old computer/how have they done that.
John,
Call Marathon and ask for that drawing. They will usually send out a drawing or 2 for the older coaches.
Many of the rear view camera systems have the following. 2 wire video or mini coax, power, ground, reverse image, up, down, left, right, and air blower.
From the switch to the monitor I can't image more than video and possibly power to trigger the monitor to switch.
