Description
Uart Can Converter Small TTL Serial RS232 / 485 Serial to CAN Adapter Transparent Converter Serial to Can Converter
Product Description
Small and exquisite, high performance, high stability serial to CAN module. It has 1 TTL interface and 1 CAN interface. The baud rate of the serial port supports 1200 ~ 460800bps; the baud rate of CAN supports 10kbps ~ 1000kbps. The firmware of the device can be upgraded through the TTL interface, which is very convenient to use. Can easily complete the interconnection between serial devices and CAN devices.

Module parameter configuration
This module can use "intelligent embedded CAN to serial port configuration software" to realize the parameter configuration of the module through the TTL interface. If the device cannot be connected due to accidental configuration errors, you can use the "CFG" signal to restore the factory parameters (pull down the CFG, hold it for 5 seconds, and release the three green indicator lights after flashing). Serial server configuration software Before configuration, you must know the RS232 / 485 baud rate of the module's last successful configuration. If you forget it, you can restore the module to the factory. The factory parameters are 115200, 8, N, 1:
After obtaining the parameters successfully, you can modify the parameters. After the modification is complete, click "Save Device Parameters", and then restart the device. The following explains the parameters in the configuration software.
