Connecting Data Transmission Cables
This section describes how to connect the UC-7101 to the network, to serial devices, and to a
serial COM terminal.
Connecting to the Network
Connect one end of the Ethernet cable to the UC-7101’s 10/100M Ethernet port, and the other end
of the cable to the Ethernet network. If the cable is properly connected, the UC-7101 will indicate
a valid connection to the Ethernet in the following ways:
y
The top-right LED on the connector glows a solid green when connected to a 100 Mbps
Ethernet network.
y
The top-left LED on the connector glows a solid orange when connected to a 10 Mbps Ethernet
network.
y
The LEDs will flash when Ethernet packets are being transmitted or received.
The 10/100 Mbps Ethernet LAN 1 port uses 8-pin RJ45 connectors. Pinouts for the port are shown
in the following diagram.
