V2426A Hardware Manual

V2426A Hardware Hardware Connection Description

Connecting the Power

Connect the 12 to 48 VDC power line with M12 A-coded connector to the V2426A computer. If the power is supplied properly, the “Ready” LED will glow a solid green after a 25- to 30-second delay.

Grounding the Unit

Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting the power.

ATTENTION

This product is intended to be mounted on a well-grounded mounting surface, such as a metal panel.

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

In this section, we describe how to connect the V2426A embedded computer to a network and serial devices.

Connecting to the Network

Connect your network cable to the embedded computer’s Ethernet port. The other end of the cable should be connected to your Ethernet network. When the cable is properly connected, the LEDs on the embedded computer’s Ethernet port turns on to indicate a valid connection.

Two 10/100/1000 Mbps Ethernet ports using M12 X-coded connectors are located on the rear panel of the embedded computer. See the following figure for the location of the Ethernet ports and the pin assignments.

NOTE

The pin assignments for the V2426A computer’s Ethernet port are shown in the following figure. If you create your own Ethernet cable, make sure that you match the pin assignments on the connector of the Ethernet cable.

Connecting to a Serial Device

Use a serial cable to connect your serial device to 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 (refer to the software manual for your operating system version).

Installing a CFast Card

The V2426A embedded computers come with a CFast socket. To insert a CFast card, complete the following steps:

1.

Disconnect the V2426A from its power source.

2.

The CFast slot is located on the left side of the front panel. Loosen the screws on the CFast socket cover.

NOTE

3.

Press the CFast card to eject it.

When you want to insert it back into the CFast slot, slide it into the slot and then push it in with your finger until it latches firmly.

Make sure that you properly orient the the CFast card when installing it; otherwise, you may not be able to insert the card all the way into the slot.
