Mine finally died so I've got to open it
up. Looking over the schematics it looks like the monitor supplies
isolated +5 VDC to the video card to drive the optoisolators.
The manual shows for the
monochrome....
1 GND
2 +5 (out)
7 Video
8 Hsync
9 Vsync
And the video card schematic shows...
1 GND
2 External Power
3 IRED
4 IGREEN
5 IBLUE
6 GND
7 VIDEO
8 HSYNC
9 VSYNC
Page 7-11 of the 9100 service manual shows MJUMP
or CJUMP to feed the ISO-PWR supply line which power the opto
isolators.
I assume CJUMP is Color JUMPER?
So this leads to 2 questions.
Must the monochrome be optoisolated & power the Video card
with +5VDC or can I use the CJUMP & run a monochrome monitor?
What is Intensity voltage level/range normally on a
monitor? (I'd like to use a non Fluke monitor)
Thanks,
Kev
