1.3 Connecting to a PC
The PK162-12 connects seamlessly to a PC and it is an excellent means of testing the functionality. To
connect your display to a PC, you will require a standard RS-232 9-pin serial cable such as the one pictured
in
figure 4 on page 3 , as well as a modified 5V power adapter such as the one pictured in figure 1 on page 2 .
In order to connect your display to a personal computer follow these easy instructions:
1. Plug the serial cable into the com port you wish to use.
2. Connect the modified 5V power adapter to a power lead from your PC power supply (you will have to
open your computer case).
3. Connect the serial cable to the DB-9 connector on the back of the display.
4. Connect the 5V power adapter to the 4-pin connector on the back of the display.
WARNING DO NOT use the standard floppy drive power connector,
as this will not provide you with the correct voltage and will damage the
display module.
