Overview

The V2426 Series embedded computers are based on the Intel Atom
N270 x86 processor, and feature 4 RS-232/422/485 serial ports, dual
LAN ports, 3 USB 2.0 hosts, and provide VGA and DVI-I outputs. In
addition, V2426 Series computers are compliant with the essential
sections of EN 50155 covering operating temperature, power input
voltage, power surges, ESD, and vibration, making them particularly
well-suited for railway and industrial applications.

The dual 10/100 Mbps Ethernet ports with M12 connectors offer
a reliable solution for network redundancy, promising continuous
operation for data communication and management. As an added
convenience, the V2426 computers have 6 DIs and 2 DOs for
connecting digital input/output devices. In addition, the CompactFlash
socket, SATA connector, and USB sockets provide the V2426

computers with the reliability needed for industrial applications that
require data buffering and storage expansion. Moreover, the 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 mini­PCI Express module, giving greater flexibility for setting up different
industrial applications at field sites.

Pre-installed with Linux or Windows Embedded Standard 2009, the
V2426 Series provides programmers with a friendly environment for
developing sophisticated, bug-free application software at a low cost.
Wide temperature models of the V2426 Series that operate reliably in a

-40 to 70°C operating temperature range are also available, offering an
optimal solution for applications subjected to harsh environments.
