Grounding the Unit

SG:

The Shielded Ground (sometimes called Protected Ground) contact is the

central pin of

the power input connector. Connect the SG wire to an appropriate grounded metal surface.

Connecting Data Transmission Cables

This section describes how to connect the V2416 embedded computers 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.

Two 10/100/1000 Mbps Ethernet ports using M12 connectors are located on the front panel. See the figure at

the right for pin assignments.

Connecting to a Serial Device

Use a serial cable to plug your serial device into the embedded computer’s serial port. Serial ports P1 to P4 have

male DB9 connectors and can be configured for RS-232, RS-422, or RS-485 communication by software. The

pin assignments are shown in the following table:
