There is one USB 2.0 mini B Port for connection to a laptop or PC. Since the chip used
is a USB-LAN chip, your PC will identify a new Ethernet Network Interface Card.

Status LED(1)
The USB 100BASE-T1 MediaConverter has one status LED at the front side of the case
for the 100BASE-T1 Port. It is lit when there is a linkup. It is toggling when there is
communication.
There is a bug in the used BroadR-Reach PHY. When the 100BASE-T1 Plus and
Minus lines are swapped, and the 100BASE-T1 port is set to Slave then the Link
LED is lit, but there is no data transmission possible. So please ensure that the
100BASE-T1 lines (positive/positive and negative/negative) are connected
correctly.
