Box PC for wireless communication with CAN

The BL50W box PC by MEN Micro (USA), a subsidiary of MEN Mikro Elektronik (Germany), is a box computer that has been designed for independent use or as display computer electronics for wireless applications in transportation, e.g. in trains, commercial vehicles, mobile machines or airplanes.

IT CAN BE USED AS A COMPLETE CONTENT or hot-spot server, as a diagnosis interface or for controlling fleet management applications or to implement communication from the vehicle to the control center and internet in the train or airplane. Four PCI Express Mini Card slots with eight SIM card slots make it possible to implement a range of wireless interfaces such as WLAN, UMTS, GSM, HSDPA, EDGE, LTE or Glonass. A fixed GPS interface complements the possibilities.
It is powered by an AMD Embedded G-Series APU (Accelerated Processing Unit), the T48N, running at 1,4 GHz. The G-Series combines low-power CPUs and advanced GPUs, in this case an AMD Radeon HD 6310, into a single embedded device. The use of the embedded G-Series makes for high scalability in CPU (single/dual core) and graphics performance (various Radeon GPUs or none at all).
The box computer is equipped with 2 GiB of DDR3 SDRAM and offers SD card and mSATA slots. A SATA hard-disk/solid-state drive can be installed within the housing. The system is designed for fanless operation at temperatures from -40 °C to +70 °C (+85 °C for up to 10 minutes). Its special aluminum housing with cooling fins serves as a heatsink for the internal electronics and in this way provides conduction cooling.
It supports up to two Displayport interfaces with full HD resolution. In addition, a multitude of other I/Os is available at the front panel, including two Gigabit Ethernet, two USB 2.0, variable slots for legacy serial I/O (e.g. RS-232) or CAN network, general purpose inputs and relay outputs.
The box PC comes with its own integrated 30 W 24 VDC nominal (10 V to 50,4 V) class S2 wide-range power supply and is compliant with EN 50155 and prepared for e1 certification. The power can be switched on and off using an ignition signal on the power connector, and a run-down time after switching off the power can be adjusted by software.
Deutsche Bahn is currently testing first prototypes of a customized version of the product. The box PCs will be used to allow precise positioning of trains giving the maximum efficiency for track usage.
