Video Server provides five more custom commands other than general pan, tilt, zoom and preset
functions. Administrators can click on and refer to the instruction manual
of the attached device to setup frequently used functions. The "Commands" should be entered in
ASCII format; Video Server will translate it into binary code and send it out through the serial
port. For instance, a text string of "8101ABCDEF" will be translated into five bytes of
hexadecimal 81, 01, AB, CD and EF. The maximal length of a command string is 60 which is
equivalent to 30 hexadecimal bytes. "Display string" is for text on command buttons and should
be less than 8 characters.
