Recommendations for twisted pair cables
Both the computer module as well as the user module each provide two RJ45 inter-
faces. These interfaces transmit the following data between the modules:
 Transmission: keyboard, video, mouse, audio (optional), RS232 (optional)
 USB 2.0-Trans.: transparent USB 2.0 signals
The following paragraphs offer recommendations regarding the applications of a
particular twisted pair cable.
Transmitting KVM data (Transmission)
The keyboard, video, mouse, audio (optional) and RS232 (optional) signals of the DVIVision
system are transmitted via category 5e (or better) twisted pair cables.
Depending on the wire gauge and the twisted pair cable that is being used, the fol-
lowing distances can be bridged between the computer module and the user module:
The following cables achieved the best results during test operation under 
lab conditions:
 up to 140 meters: G&D K-C7-LD; Kerpen MegaLine ® G12-150 S/F (AWG 22)
 up to 100 meters: G&D K-C5-HR; Dätwyler uninet ® 5502 4P / 2x4P BD (AWG 24)
NOTE: It is permitted to connect several segments of a cable connection with patch
panels and connection ports.
It is not permitted to connect active components such as network switches, hubs
or repeaters are not permitted.
Wire Gauge Cable Type Category Recommended
