1.4 Connecting to a PC
The GLK19264-7T-1U Non-USB connects seamlessly to a PC and it is an excellent means of testing the
functionality and uploading new fonts and bitmaps. You will require a standard RS-232 9-pin serial cable
such as the one pictured in Figure 8, as well as a modified 5V power adapter such as the one pictured in
Figure 4.
In order to connect your Non-USB 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.
