Connecting Data Transmission Cables

This section describes how to connect the MC-5157-AC/DC computer to the network and serial devices.

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 10/100/1000 Mbps Ethernet LAN port uses 8-pin RJ45 connectors. The following diagram shows the

pinouts for these ports.

The LED indicator

s on the

right top and right bottom corners glow 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.

The LED indicator

s on the left top and left bottom corners glow a solid yellow color

when the cable is properly connected to a 10

Mbps Ethernet network. The LED will
