The 3D Series CAN bus Display and the 3J Series Vehicle Display Controller from Grayhill provide what it says is a complete human-machine interface. The display is suitable for monitoring gauges, diagnostic menus, and video feeds. The Vehicle Display Controller, mounted within easy reach, provides an efficient means of navigating through the on-screen software. Either Linux or Microsoft Windows O/S can be specified for the easily customized embedded computer. Both devices include SAE J1939 compliant CAN interfaces and are tested to withstand the harsh conditions in off-highway vehicles.
