CX2550-0179 - Architecture description

Within the USB extension the length of USB data transmission can be increased from 5 meters up to 58
meters. This is a USB 1.1 connection. Due to the USB signal runtime, it is not possible to connect more than
one USB hub in the chain.

The following image shows the possible configuration with the maximal allowed distances:

The USB hub has to be connected after the extension. The maximal distance is 58 meters: 50 Meter cable
from CX2550-0179 to the extension box CU8850, 3 meters from the extension box to the USB hub and 5
meters from the USB hub to the USB device.

Via the USB extension a Beckhoff Touch Panel can be connected. Thus a panel of type CP69xx/79xx can be
operated up to 50 meters from the CX system without additional devices.
