Troy,
Thanks for the quick response.
I'll will tie all 3 pins together as GND and try it out later tonight. I assume as soon as 3.3V power is applied (no reset, button press or RS232 connection required), the display will illuminate with some basic firmware boot message.

I'm finally getting back to this project.
Please verify the 3.3V power connections. This is the 5.5V connector pinout. Of course the 5.5V (in red) is replaced with a 3.3V.

Should the 2 GND in the middle be tied to the GND on the far right?

Are there additional application notes for the GLK19264-7T-1U-GW-LV beyond the following?
- GLK19264-7T-1U Manual for PCB revision 1.0
- GLK19264-7T-1U Autocad drawing for PCB revision 1.0
Are there schematics available? A few pdfs would be useful.

This is the low voltage display which runs on 3 ...
