9 protocols are available: CAN High, CAN Low, LIN, FlexRay, RS232/UART, I2S,
I2C, USB (1.0/1.1), and CAN FD. The detailed setting options vary according to each
protocol.
CAN High / CAN Low: Controller Area Network (CAN) is a serial protocol used
in automotive to allow microcontrollers to communicate with each other. It
typically uses differential signaling ( with signals named CAN High and CAN
Low) to increase noise immunity.
LIN: Local Interconnect Network (LIN) is a serial protocol used in automotive
electronics to allow microcontrollers to communicate with low-speed
peripherals.
FlexRay: It is an automotive network communications protocol for high-speed
data.
RS232/UART: Universal Asynchronous Receiver/Transmitter (UART) is the
communication interface found in the serial or COM ports once commonly
found on computers. Each channel of data is transmitted on a single wire pair
using an electrical standard such as RS232.
