Connecting Data Transmission Cables
This section describes how to connect cables for the network, serial devices, and serial COM
terminal.
Connecting to the Network
Plug your network cable into the embedded computer’s Ethernet port. The other end of the cable
should be plugged into your Ethernet network. When the cable is properly connected, the LEDs on
the embedded computer’s Ethernet port will glow to indicate a valid connection.
The 10/100 Mbps Ethernet LAN port uses 8-pin RJ45 connectors. The following diagram shows
the pinouts for these ports.
The LED indicator on the right glows a solid green
color when the cable is properly connected to a 100
Mbps Ethernet network. The LED will flash on and off
when Ethernet packets are being transmitted or
received.
