UC-8540 - ARMv7 Cortex-A7 1GHz Embedded Rail PC with one WWAN, one WLAN and EN50155, EN45545 and EN50121 certification
CE is a mandatory standard for products on the market in the European Economic Area. By CE marking a product, the manufacturer ensures that the item meets the essential safety requirements set out in the applicable CE directive.
This product fully adheres to the Restriction of Hazardous Substances Directive 2002/95/EC, RoHS for short.  The directive covers the restriction of use of certain hazardous substances in electrical and electronic equipment and was adopted in February 2003 by the European Union.
Underwriters Laboratories (UL) is an independent product safety certification organisation based in the United States. UL develops standards for products, materials, components, assemblies, tool and equipment, mainly dealing with product safety.
These products use heatsink, heatpipe and extrusion technology to dissipate the heat generated by the system rather than using traditional fans thus improving system reliability and longevity.
These devices utilise a low-cost, low-power ARM-based processing platform making it an ideal solution for embedded applications.
EN 50155 is the European standard for electronic devices used in railway applications. The device must adhere to the strict specifications of EN 50155 including -25C to +70C wide operating temperature range, resistance to humidity, shocks, vibrations and radiation – all environmental demands encountered in the rail industry.
These devices and systems have been designed to accept a wide voltage DC power input. This feature is desirable in the industrial market where a fixed voltage level or mains AC power cannot be guaranteed.
The Federal Communications Commission (FCC) is an independent agency of the United States government that sets standards and governs the testing of conducted and radiated emissions such as EMI.
These products utilise high quality industrial grade components enabling them to work in wide temperature environments. They are capable of running as low as -20C and as high as +70C.
These products utilise high quality industrial grade components enabling them to work in extended wide temperature environments. They are capable of running below -20C and above +70C and offer further protection than standard wide temperature rated products.
These products come with a standard five year manufacturer warranty.

Moxa’s UC-8540 RISC rail computer built around the ARMv7 Cortex-A7 1GHz processor and 1GB of pre-installed DDR3L system memory. Its single-sided I/O design is ideal for transportation applications, where room for installing communication devices is often limited. The front-side access enables easy to installation or replacement of SIM cards and wiring cables. Wireless modules and RTC batteries and mSATA cards can easily be installed of replaced from the top or bottom.

The UC-8540 embedded PC has one miniPCIe slot with USB signal to support a 4G/LTE module and one slot with PCIe/USB signal to support a Wi-Fi module. The 4G/LTE module has two SIM card slots, which can be used to enable redundant cellular network communications or geo-fencing SIM card selection by leveraging the built-in MIRF 2.0, a Moxa device remote-management platform with wireless management.

The UC-8540 can be used as a communication-centric computing platform in applications such as vehicle-to-ground communication gateway, TCMS T2G (train-to-ground) gateway, mobile condition monitoring unit, Ethernet Consist Network T2G gateway, and onboard wireless automated fare collection unit. Wireless modules are sold separately. 

The UC-8540 uses an open platform based on Debian 8 with Linux kernel 4.1, allowing solution providers to manage software packages via Debian’s APT (Advanced Packaging Tools), or develop software applications with Moxa’s API Library and GNU C Library.
