Connecting the TN-USB3-xx-01
This section describes how to connect the TN-USB3-xx-01 to a PC/Notebook/Tablet. The TN-USB3-xx-01 can be
used to allow a portable device, like a laptop or tablet computer, to connect to a fiber based Gigabit Ethernet
network, via its USB 3.0 port, providing secure network access over a fiber infrastructure.
TN-USB3-xx-01 Connections
The figure above shows USB 3.0 connections for a TN-USB3-xx-01 to a desktop PC, a laptop PC, and a tablet.
The procedure is provided below.
1.Insert the TN-USB3-xx-01 USB connector into an available USB 3.0 port on your computer or device.
Note: For maximum performance, connect the TN-USB3-xx-01 directly to a USB 3.0 port on your computer.
If you are connecting to a USB hub, make sure it operates at USB 3.0 speed and can provide the required
power for this device. A USB 2.0 hub will also work, but only at USB 2.0 speeds.
2.Insert one end of a fiber Ethernet cable into the FIBER port of the TN-USB3-xx-01.
3.Insert the other end of the Ethernet network cable into an Ethernet port on the other end.
4.If the TN-USB3-xx-01 is discovered by your computer, continue operation. Note that the first time you plug
in the TN-USB3-xx-01, it may take 2 full minutes for the driver to install, before it begins working.
If the TN-USB3-xx-01 is not discovered, install the driver; see the “Driver Installation” sections below.
Note that it will not appear as TN-USB3-xx-01; it will appear as the Asix chip (i.e., the USB 3.0 to Gigabit Ethernet
controller).
