Selecting DDC information

Since the monitor is connected to the user module and not directly to the graphic
output of the computer, the computer cannot access the DDC information of the
monitor.
For this reason, preset DDC information that are provided to the computer are
stored in the target modules of the CATpro2-DVI-Audio series. Additionally, the
DDC information of the monitor can be read out and stored in the target module.
