NOTE The keypad is not used to directly control any aspect of the operation of the
display. The display acts simply as a matrix to serial converter.
1.4 Setup for Testing
Before setting up the application, it is best to test out the display. This is easily done with a PC.
The following is a list of requirements for testing;
• An available powered USB source
• USB Drivers which can be located on Matrix Orbital’s website and eCD
• Test software such as Alpha Demo or Display Tuner
Once the above test requirements have been met, the user may proceed with the following steps;
1. Refer to the diagram above for the following steps.
2. Download or copy the USB drivers into a directory.
3. Uncompress the files. They will be a self extracting ZIP file.
4. Connect the USB cable to the display and the computer.
