Within the USB-Extender-TX (CU8800) and USB-Extender-RX (CU8860) the length of USB data transmission can
be increased from 35 meters (1 host, 5 USB hubs and a device connected with 5 meters cable) up to 61 meters.
Due to the USB signal runtime, it is not possible to connect more than one USB hub in the chain. The DVI signals
are extended up to 55 meters. The following pictures show the maximal length of connection for possible
configurations:
This configuration (1) contains no additional USB hub. The maximal distance of extension is 56 meters: 1 meter of
cable to the extension box CU8800; up to 50 meters extension cable and 5 meters from extension box to USB
device. The DVI cable can have a maximal length of 50 meters to the extension box. From there the DVI signal can
be transmitted up to 5 meters.
This configuration (2) contains an additional USB hub. The USB hub is connected directly to the host computer.
The maximal distance of extension is 61 meters: 5 meters of cable from USB host to the USB hub; 1 meter cable to
the extension box CU8800; up to 50 meters extension cable and 5 meters from extension box to USB device. The
DVI Signal is also extended to maximum 55 meters. (see configuration1)
