1.1 What to Expect From the GLC24064
The GLC24064 is designed as the display unit for an associated controller. The controller may be
anything from a single board, special purpose micro-controller, to a PC depending on the application. This
controller is responsible for what is displayed on the screen of the display.
The display provides a simple command structure which allows both text and graphics to be transferred to
the screen. Text fonts (and graphics, if desired) are stored in the display’s flash ROM and may be regarded as
’permanent’, in that they will survive power-off periods and will not change until explicitly reprogrammed.
The screen is backlit for low-light situations. Backlighting may be turned on or off under program
control. Contrast is adjustable to compensate for differing lighting conditions and viewing angles.
1.2 What Not to Expect From the GLC24064
Since the display is intended to be used with a controller it does not have any built in text editing
functions. If a stream of ASCII characters are inputed, those characters will be displayed. However, the CR,
LF, backspace, etc., will be ignored. If the application requires these functions, they must be provided by
the software in the controller, which will issue the appropriate positioning commands to the display. The
display does not include a keypad interface.
1.3 mogd.exe
Matrix Orbital has developed an interface program which exercises all the features of the display. The
program can be used to manage font and graphics downloads. "mogd.exe" is provided on Matrix Orbital’s
Cd and website.
To install mogd.exe, follow the following steps;
1. Insert the Matrix Orbital Cd-ROM into the Cd drive
2. Locate the file "mogd.zip", which should be in the “Download” directory
3. Unzip mogd.zip to a temporary directory using a program such as Winzip, Pkzip, etc.
4. Double click on "setup.exe"
5. Follow the instructions on the screen to complete the installation
After the installation is complete there will be a Matrix Orbital entry under “Programs” in the “Start menu”.
Click on this entry to run mogd.exe.
The following information must be entered the first time mogd.exe is run;
