dxPC is a mobile Windows-based personal computer designed for the demanding environment of heavy vehicles. The computer consists of a 12 inch colour touch screen a robust computer unit encapsulated in a strong aluminium cover, and an environment adapted keyboard with a trackball.


Screen and computer can be mounted as a single unit with the computer fixed on the back of the screen. The screen and computer can also be mounted individually, up to three metres from each other, thus facilitating fitting in various cabs and


dxPC has three CAN bus connections and is prepared for connection to dasa4 and dasa5 control and communication systems.
