USER CONTROLS - ADVANCED USAGE
The functions described above can also be accessed via the DDC (Display Data Channel) provided over the DVI-I
port and through it you can access all frontal symbols (including Light Sensor, Alarm LED, Buzzer) and their
functionality to allow extended usage for your 8 and 13 inch Display units - all controlled by your software.
Implementation:
The easiest/quickest way to implement control of the DDC in a Microsoft® Windows® environment application is to
use a library designed for this task. An example of such a library is the
WinI2C-DDC - http://www.nicomsoft.com/products/i2c
Similar solutions might be available for Linux, but that is outside the scope of this user manual.
“WinI2C/DDC is a professional tool that allows you to control display devices in the Windows environment via the
DDC/CI protocol. It allows you to send DDC/CI commands via the standard video cable (VGA or DVI) and control all
display devices that support the DDC/CI protocol: CRT/LCD monitors, projectors, plasma panels, etc.”
