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-IP-CPU ) can already access the features of the remote monitor during boot-
ing, 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 pro-
vided 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).
