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.

2.1.2 Power through the DB-9 Connector

The LK162-12 can be powered by pin #9 on the DB-9 connector. If power is applied here, power cannot be

applied to the other power connector. The input voltage for pin #9 can only be +5Vdc, even if the unit is

wide voltage. Not following these instructions can destroy the unit.

To use the DB-9 connector for power you will have to solder a jumper as show in the bellow image.
