Software
The multiple communication protocols available and simple command structure of the LVK204-25
means that a variety of applications can be used to communicate with the display. Text is sent to the
display as a character string, for example, sending the decimal value 41 will result in an 'A' appearing on
the screen. A number of control characters are also activated. Commands are merely values prefixed
with a special
command byte, 254 in decimal. While many software programs are available to
communicate with the LVK204-25, a number of more common samples
are detailed in depth below.

Once the correct communication port is identified, the following communication settings can be applied
to communicate correctly with the LK204-7T-1U.

Finally, with a communication port identified and correctly setup simple text
strings or even command
bytes can easily be transmitted to control your display.

uProject
The Matrix Orbital alphanumeric display tuner, or uProject, is offered as a free download from the
www.matrixorbital.ca support site. It allows the basic functionality of any display*
to be tested using a
simple graphical user interface system.
While basic functionality can be tested using the GUI portion of the program, more advanced users will
enjoy the scripting capability found in the uploader tab. Here commands can be stacked, run, and saved
for later use. Although many commands are available to be dragged into the script dialog, perhaps the
most powerful is the raw data command found in the other branch.
*Note:
The uProject AutoDetect function will not perform correctly when a USB display is connected. Please
manually configure any USB display.
