  DESCRIPTION
The Opus A3F and A3S Wachendorff display units are cost-efficient, rugged operator control panels for use on heavy-duty vehicles and work machines that must operate outdoors in harsh conditions. They are fully equipped with an encoder, three hard and eight soft-function keys, integrated buzzer, RS232 and USB ports, and CAN bus. The A3F (full-featured) unit has analog/digital inputs, digital outputs, Ethernet and video connections for use with a camera to monitor process operations.

RATINGS
Display: Sunshine-readable thin film transistor (TFT) color graphic LCD.
   480 x 272 pixel resolution, viewing angle ± 50°, 4.3 inch (109 mm) diagonal
   screen. Light gray plastic housing with black rubber frame; glass front with
   anti-reflective foil surface.
Mounting: Can be mounted in landscape mode; stand-alone or on
   dashboard. To mount stand-alone, use the 4-bushing M5 of the rear panel
   with the A3 adaptor cover Part #4000405. To mount on dashboard use Part
   #4000406.

*Note: Car Ground (Pin #4) must be connected to the chassis by a conductor as short as possible. Even if there is no conductive chassis available (e.g. in E-vehicles) the pin has to be connected to the negative pole of the battery. Otherwise, there will be no protection against over-voltage, shortout or electrical shock discharge (ESD).
