Transmission Of Usb Data Of Aru2 Variants; Ddc Transmission With Cache Function - G&D DP1.2-Vision-CAT Installation Und Bedienung

Transmission of USB data of ARU2 variants

The USB 2.0 signals of the
ted via category 5e (or better) twisted pair cables.
Depending on the wire gauge and the type of twisted pair cable, the following dis-
tances can be bridged between computer module and user module:
Wire gauge Cable type
AWG 22 Installation cable
AWG 24 Installation cable
AWG 26 Patch cable
The following cables achieved the best results during test operation:
 up to 100 metres: Dätwyler uninet ® 5502 S-STP (AWG 24)
 up to 80 metres: Dätwyler uninet ® 7702 Flex (AWG24)

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 user 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
(

booting, the KVM extender contains a cache function. Even when the computer
module or the user 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).
