The AT8-series interface from Graf-Syteco is ideal as an in-vehicle control panel for CANbus systems. It combines a high-visibility quarter-VGA colour TFT display with programmable function keys to offer simple operator control of Controller Area Network systems typically employed in vehicle systems such as engine or transmission management or in vehicle mounted machinery such as lifting gear or agricultural equipment.
The unit can be supplied with either one or two CANbus interfaces, allowing a single operator interface to be switched between two separate systems, without interrupting the operation of either network.
The AT8-series HMI is ruggedly constructed to withstand the rigours of the commercial vehicle environment. Available for dashboard mounting or as a fully enclosed unit, the front panel is sealed to IP65, and the high-quality assembly is qualified to IEC standards for shock, vibration and electromagnetic compatibility, including Level II automotive load dump resistance.
The high-visibility TFT liquid crystal display features 320 x 240 pixel resolution with a screen size of 111 x 83.5mm. This makes it suitable for displaying both text and graphics. And with an optional interface the AT8 can even display video, for example from a reversing camera, adding further versatility to this all-round performer.
The controls of the AT8-series interface are designed for ease of use. The eight pushbuttons and single potentiometer enable single-handed control, and all the controls feature halo illumination to enable night-time operation. The functions of all the controls are freely programmable, and the complete HMI can be programmed in C or using optional graphical programming software.
The AT8-series HMI runs from a wide power supply range from 10 to 32V DC (covering both 12 and 24V automotive battery voltages), typically consuming just 600mA from a 24V DC supply. Internal backup batteries may be specified as an optional extra to maintain control of critical systems should the main vehicle supply fail.
