MEX Hardware Manual, Release 1.0
1.1 Wiring Optimization
It is especially in large vehicles, where wire optimization plays a critical role permitting a significant weight reduction.
This upgrade is achieved thanks to the reduction of cable length and because of the added flexibility so the right device
can be installed in the right location. Another advantage of the use of Veronte MEX is the robustness of the CAN
Bus, being resistant to electromagnetic interferences and permitting the installation of long cables with no signal loss.
Furthermore, it includes redundancy with CAN bus isolation, making it fail operational even in case of a CAN bus line
break.
1.2 Extended I/O
With the use of Veronte MEX, the data capacity for input and output in Veronte Autopilots is increased in a great
manner. The advanced design makes possible to control several peripherals (PWM, RS-232, RS-485, digital output,
I2C, analog inputs...) through the CAN Bus. It can be used for both, expanding the I/O capacity in Veronte Autopilots,
or for controlling peripherals with a robust communications protocol. In case it is needed, multiple Veronte MEX boards
can be installed in the same network for increasing the number of I/O ports or because of system architecture needs.
1.3 Applications
In aviation, a field where weight means such an important agent in design, struggling with wiring is one of the most
common issues faced during the vehicle design. With the use of Veronte MEX, not only this issue would be reduced,
but a bunch of opportunities for different sensors and payload could arise:
•By adding more I/O interfaces, a more complex payload control can be achieved, improving connectivity.
•Advanced control of actuators and peripherals becomes feasible, being possible to condensate the connection of
control, feedback, sensors... in a single board.
•Devices can be installed at long distances from the autopilot with no signal degradation thanks to the robustness
of the CAN Bus.
•The internal magnetometer allows to measure differences of altitude and orientation, useful for navigation
applications. The magnetometer measurements are sent through RS-232, RS-485 or CAN channels to other
devices, like any other variable.
