CAN485 User Manual, introduces RS485 interface protocol, interface definition, jumper setting, LED indication, and precautions.
The CAM85 converter provides transparent conversion between RS485 and CAN bus signals. It supports a wide range of baud rates for both interfaces and includes LED indicators for status monitoring.
The manual describes the connector pin assignments, jumper configurations, and operating parameters such as power consumption, temperature range, and supported communication speeds. It also lists the internal components like the CPU, CAN controller and RS485 transceiver. This manual is written in Chinese.
