2.1.1.2 Wide Voltage Range Modules
Note: Do not use this cable unless your display module has the "wide voltage range" option (option V). Use
of the 12 volt power cable with 5 volt modules will damage the module.
The 12 volt power cable is designed for use with wide voltage range display modules mounted in a PC.
Wiring required for the 12 volt power connector is shown in Figure 2-5 below.
If you don't want to modify cable wiring yourself, Matrix Orbital can supply an adapter cable designed to
use with the display module when it's installed in a PC. The cable is wired as shown in Figure 2-6 below.
