Connecting Data Transmission Cables
This section describes how to connect the W315/325/345 embedded computers to the network,
serial devices, and a 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.
