The Veethree display is a versatile electronic device designed for monitoring various parameters in marine and industrial applications. It comes in several series, including T-Series (touch screen color displays), R-Series (round housing displays), C-Series (color displays), and M-Series (monochrome displays), each offering different form factors and functionalities to suit diverse needs.

Function Description:

The primary function of the Veethree display is to provide real-time visual feedback on critical operational data. Depending on the model and configuration, it can display information such as engine RPM, speed (MPH), water temperature (°C), battery voltage (volts), and other sensor readings. The displays are designed to integrate with CAN (Controller Area Network) protocols, allowing them to communicate with various engine management systems and other networked devices. Some models also feature USB ports for external I/O, RS232/RS422/RS485 communication, and digital/analogue inputs/outputs for expanded functionality. The touch screen models (T-Series) offer an intuitive user interface for easy navigation and data interaction.
