4.1 Architecture Description
Within the USB2.0-Extender-Tx (CU8801) and USB2.0-Extender-Rx (CU8851) the length of USB data
transmission can be increased from 35 meters (1 host, 5 USB hubs and a device each connected with 5
meters of 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 following picture shows the maximal length of connection.
4.1.1 Configuration 1
The USB hub is connected after the extension. The maximal distance is also 61 meters: 1 meter of cable
from USB host to the USB extension box CU8801; up to 50 meters extension cable; 5 meters from
extension box to USB hub and 5 meters of cable to the USB device.
4.1.2 Configuration 2
This configuration shows a CP29xx/ CP39xx Control Panel connected to the CU8801 extension box. The
maximal distance of extension is 51 meters: 1 meter of cable from the host computer to the CU8801
extension box; up to 50 meters extension cable to the Control Panel.
