Further information
DDC transmission with cache function
The KVM extender supports Enhanced-DDC (Enhanced Display Data Channel) to read
out the data from the monitor that is connected to the console module and transmit
them to the computer. This data includes information regarding the preferred reso-
lution and the supported monitor frequencies.
To make sure that the computer connected to the computer module ( )
VisionXS-CPU
can already access the features of the remote monitor during booting, the KVM
extender contains a cache function. Even when the computer module or the console
module are switched off or the devices are not interconnected, the properties of the
most recently connected monitor or a default data block are provided in the KVM
extender.
The monitor's DDC information is usually transmitted one-to-one to the computer.
Should the KVM extender determine that the display cannot be read without errors
or that the entries are invalid, the information is completed or corrected (if possible).
