Programmable Converter for RS-232 to CAN and CAN FD

The PCAN-RS-232 FD is a programmable module for converting data traffic between its RS-232 interface and CAN FD connection. For example, machines, PLCs, sensors and actuators with a serial interface can be flexibly integrated into classic CAN or modern CAN FD buses.

The behavior of the PCAN-RS-232 FD can be programmed freely for specific applications. The firmware is created using the included development package with GNU compiler for C and C++ and is then transferred to the module via CAN. Various programming examples facilitate the implementation of own solutions.

On delivery the PCAN-RS-232 FD is provided with a standard firmware that routes from CAN FD to RS-232 and vice versa. It allows to configure the data transfer as well as the hardware with serial control commands. The corresponding source code is included as an example in the scope of supply.

REQUIREMENTS

The transfer of the firmware via CAN requires a PEAK CAN interface.
