CATVision-USB 2.0 series
The KVM extenders of the CATVision-USB 2.0 series transmit the signals of key-
board, mouse and USB devices as well as the video signal between a remote console
and the computer.
A CATVision system consists of two main components:
 Computer module: The computer to be operated is connected to the computer mod-
ule (CATVision-CPU).
Additionally to the remote console, an (optional) local console can be installed at
the computer module.
 User module: The devices of the remote console (monitor, keyboard, mouse as well
as USB devices) are connected to the user module (CATVision-CON).
A twisted pair cable (category 5 or better) connects the computer module to the user
module.
The distance to be bridged depends on the quality of the twisted pair cable (see Rec-
ommendations for twisted pair cables on page 15) and the signals to be transmitted:
Additional functions of expanded variants
 Audio: The Audio transmission (only available in combination with the RS232 option)
enables the bidirectional transmission of audio signals between the remote con-
sole and the computer.
 Delay: The Delay function compensates the runtime delays of the different colour
channels of the RGB video signal. Those runtime delays result from the different
wire lengths of the twisted pair cabling. Through this compensation, the image
can be displayed in the best possible way.
 RS232: The RS232 transmission enables the connection of external serial devices at the
user module. The user module and the computer module are used to transmit the sig-
nals of the external device transparently between the device and the computer.
Available expansions
 CV-Power: The CV-Power expansion enables the user to operate the ATX-Power and
Reset button of the computer at the remote console.
