If the LK162-12 is used in a PC it is tempting to plug a spare power connector into the unit. Don't do this!

Wiring for the PC power connector and that required for the LK162-12 are different as shown in Figure 2-3

below.

Figure 2-3 Power Connector wiring differences

If you don't want to modify cable wiring yourself, Matrix Orbital can supply an adapter cable designed to

use with the LK162-12 when it's installed in a PC. The cable is wired as shown in Figure 2-4 below. Note

that this cable does not provide connections for I

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.
