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.

Hyperterminal
Installed on most Windows computers, hyperterminal can be run by selecting run and typing 'hypertrm'
in the command line. This basic program will allow communication between a PC and your display.
When starting up, a name must be given to your connection, and an icon may be chosen, neither is
consequential. Next, it's important to select the appropriate communication port to which
your display
is connected. Finally, the settings below must be entered to complete the port setup.

Once a port is successfully set up, data can be sent to an attached display by typing on the keyboard. At
this point, it may be helpful to echo keys to the monitor by selecting properties from the file menu and
opening the ASCII settings from settings tab.
Commands can be sent to an attached display by issuing decimal commands using the number pad.
While the ALT key is held down, four digit decimal values can be sent as a single ASCII character. For
example, to clear the screen,
try the following sequence.
ALT +0254
ALT +0088

Any commands or text desired can be sent to the communication port using this method to provide
total control of any Matrix Orbital display.
