While inheriting the basic functionality of the previous BX-300 Series, this product achieves further
decreases in power usage and increases in speed while maintaining sufficient performance by employing
a low power platform featuring the Intel® Atom™ Processor E3845 for the CPU
- Contributes to equipment miniaturization. PC functionality and expandability concentrated into a
small form (94.0 (W) x 120.0 (D) x 74.7 (H))
The small chassis (94.0 (W) x 120.0 (D) x 74.7 (H)) is equipped with a variety of interfaces including
VGA, USB3.0 x 1, USB 2.0 x 3, RS-232C x 2, LAN x 2 (1000BASE-T, 100BASE-TX), Audio, and the
F&eIT I/F (for F&eIT Series device modules). This product is also equipped with a PCIe connector that
can be connected to an external expansion chassis. This product has the same dimensions as the previous
BX-300 Series products, so it can be swapped into existing systems.
- Fanless design reduces maintenance and inspection work
This product features a completely spindle-free design that eliminates the CPU fan and uses a CFast card
for storage. The use of components that deteriorate with age has been held down as much as possible,
which greatly reduces the burden of maintenance and inspection work.
- Remote power management functions that save operational labor
This product supports Wake On LAN to externally start the PC via the network and Power On by Ring to
start the PC by the modem receiving a call. This makes it capable of providing large operational labor
savings.
- Freely expandable peripherals. Twin CFast card slots and other abundant interfaces
This product is equipped with expandable interfaces including 1000BASE-T x 2, USB 3.0 x 1, USB 2.0 x
3, and serial interfaces (RS-232C) x 2.It is also equipped with two CFast card slots (one slot isinternal)
so the data and operating system can be separated. This is very convenient for forms of operation such as
using one slot to run the system and one slot for maintenance, or using one slot to take home system logs
and sampled data.
- Usable as a controller for F&eIT Series measurement, control, and communication devices *1
This product can be used as a controller for F&eIT Series measurement, control, and communication
devices. Device modules including digital I/O, analog I/O, and serial communication can be used as
measurement, control, and communication devices.
- Up to eight F&eIT Series device modules can be connected to the F&eIT I/F *1
The F&eIT I/F can accommodate up to eight F&eIT Series device modules (maximum total current of
each module is 3A or less).
*1 WindowsEmbedded Standard 7 32bit only
- Expandable with PCI boards and/or PCI Express boards
With a single separately sold cable, this product can connect to a PCI Express Cable expansion chassis
which enables expansion by PCI/PCI Express boards.
- Possibly installed in 35mmDIN rail
A detachable metal installation part for attaching the main unit to a 35mm DIN rail is bundled by default,
which can be used according to the installation conditions. The system features a unique configuration for
its connection to a module on the side in a stacking manner, which allows you to configure the system
simply and elegantly without using backplanes and other connecting devices.
