With a protocol converter, ESS starts marketing its own products in 2002. Inspired by a new, powerful microcontroller from Atmel, which was used in a customer-specific development, a small and smart CAN to RS232 converter was created, which got the name CANgine No.1. Its hardware formed the basis for other devices, e.g. CANgine COP, which converts between CANopen and RS2323. Even today, these devices are used in process engineering and automation (e.g., in wind generators) to make simple control boards CAN capable.
On the basis of the CANgine No.1 hardware the entrance into the telematics took place in 2003. With the CANgine FMS, ESS introduced the first converter, which converts the SAE J1939 based commercial vehicle protocol FMS into serial RS232 data which is provided to telematics computers for further processing. Thanks to the flexible configuration capability of the CANgine FMS, it was able to establish itself quickly on the market.
The CANgine 1 series has meanwhile been replaced by the CANgineLight, which is based on a modern Cortex M0 core. The applied Cortex Controller is equipped with an integrated CAN controller and allows the highest performance in the processing of the CAN data.
