1. Introduction
The V2406/2422/2426 embedded computers are based on the Intel Atom N270 x86 processor, and feature
four RS-232/422/485 serial ports, dual 10/100 Mbps (10/100/1000 Mbps for V2422) LAN ports, 3 USB 2.0
hosts (6 for V2422), and a CompactFlash socket. The V2406/2422/2426 computers provide VGA, DVI-I
outputs, and digital input/output channels, making them particularly well-suited for industrial applications such
as SCADA and manufacturing automation.
In addition, the CompactFlash and USB sockets provide the V2406/2422/2426 computers with the reliability
needed for industrial applications that require data buffering and storage expansion.
The V2422 and V2426 computers come with 2 peripheral expansion slots for inserting different communication
modules, such as a 2-port CAN module, an HSDPA, GPS, WLAN module, an 8+8 port digital input/output
module, a 2-port serial module, a mini PCI expansion module, and a PCI Express module, providing greater
flexibility for setting up different industrial applications at field sites.
Pre-installed with Linux, Windows Embedded Standard 2009, or Windows Embedded Standard 7, the
V2406/2422/2426 computers provides programmers with a friendly environment for developing sophisticated,
bug-free application software at a low cost.

Installing the V2406/2422/2426
Wall or Cabinet Mounting
The V2406/2422/2426 comes with two metal brackets for attaching it to a wall or the inside of a cabinet.
Step 1: Use two screws for each bracket and attach the bracket to the rear of the V2406/2422/2426.
Step 2: Use two screws per side to attach the V2406/2422/2426 to a wall or cabinet.
Din-Rail Mounting
The V2406/2422/2426 can be installed on a DIN-rail with the optional DIN-rail kit. This DIN-rail kit must be
purchased separately. It includes two DIN-rail brackets and eight screws.

V2406/2422/2426 Hardware Manual Hardware Connection Description
3-3
To attach the DIN-rail kit, turn the V2406/2422/2426 over to the bottom cover. Find the locations for the
screws and place the brackets on the cover. Please note that all eight screws must be firmly attached so that
the computer can be securely installed on the DIN-rail.
When the brackets are firmly attached with the screws, it can be installed on a DIN-rail
To release the DIN-rail kit, simply use a screwdriver to push down the lower part. Please use at least two
persons to do this step as once the DIN-rail kit is pushed down, the computer will be detached immediately
from the DIN-rail.
To re-install the computer on the DIN-rail, use a screwdriver to press the buckle so that it can be released. Now,
it can be re-installed on the DIN-rail.

Wiring Requirements
This section describes how to connect serial devices to the embedded computer.
You should read and follow these common safety precautions before proceeding with the installation of any
electronic device:
•Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring together with power wiring in the same wire conduit. To
avoid interference, wires with different signal characteristics should be routed separately.
•Use the type of signal transmitted through a wire to determine which wires should be kept separate. The
rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
•Keep input wiring and output wiring separate.
•It is advisable to label the wiring to all devices in the system.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your V2406/2422/2426.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Be careful when handling the unit. When the unit
is plugged in, the internal components generate heat, and
consequently the outer casing may feel hot to the touch.
Connecting the Power
The PC’s power source should be provided by a UL listed class 2 or “Limited Power Source” (LPS), with external
adaptor output rated 12 to 48 VDC (9 to 36 VDC for V2422) , . 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. Please note
these products are intended to be mounted to a well-grounded mounting surface, such as a metal panel
V2406/V2426
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.
V2422
SG: The Shielded Ground (sometimes called Protected Ground) contact is the
left-most
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 V2406/2422/2426 embedded computers to the network and serial
devices.
Connecting to the Network
V2406/2426
Plug yo
ur 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 conn
ection.
Two 10/100 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:
