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 a portion of EN
50155 specifications, covering operating temperature, power input
voltage, power surges, ESD, and vibration, making them particularly
well-suited for railway and industrial applications.
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.
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
Pre-installed with Linux, Windows Embedded Standard 2009,
or Windows Embedded Standard 7, 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.
