When developing new control systems, it’s important to perform testing of the new control methodologies within the target network. However, different control systems may operate on different communications buses.
Communications gateways are efficient solutions for exchanging information over two or more communications buses within vehicles.
A typical application of communications gateways is when the contents of a particular communications bus needs to be adapted for reasons of compatibility to allow error free communications; such as when new electronics controllers are introduced into an existing system.
Our Simulink-Reprogrammable controller, MICROGen, can gateway between CAN to LIN, CAN to CAN, and many other commonly used protocols.

Thanks to its physical layer support for High Speed CAN, LIN, RS485 and RS232, MICROGen can quickly convert incoming information for onward transmission, via a range of automotive I/O including analogue, digital and PWM. Thus, broadening compatibility between disparate systems and their networks.
Using a model-based design for the communications gateway facilitates rapid design of the application for the exchange of communications data. It also supports the design of more complex functions such as translation of units, scaling and online calibration.
Additionally, discreet I/O can be introduced to or extracted from the communications bus to support additional hardware that may have been added or changed.
