Grayhill's Series 3J Vehicle Display Controller (VDC) is an operator interface device for on-board software. The VDC features an optical rotary encoder for scrolling through menu options and a center pushbutton for selecting options. Five "hot key" pushbuttons are placed around the center shaft to quickly pull up the most common functions. Legends on the hot keys can be chosen from a library of ISO standard legends or customized with new symbols. An optional 8-way joystick provides cursor control for navigating on-screen. CANopen and J1939 protocols are available as standard options.
