Supports bidirectional USB to RS485 communication. Provides intuitive monitoring of power and signal transmission/reception status via a three-color LED indicator. Terminal resistors can be enabled/disabled via a DIP switch. Stable current and voltage output, strong surge resistance, protection against overcurrent and overvoltage, and electrostatic discharge. Maximum communication rate up to 921600bps. The MKS USB to RS485 converter is a high-speed, stable, reliable, and highly compatible serial port converter. This module uses the original FT232RL chip/CH343G chip (optional). Built-in surge protector effectively suppresses surge voltage and transient voltage spikes in the circuit, while a self-resetting fuse and diode provide short-circuit protection. Supported operating systems include , Linux, Android, WinCE, and 11/10/8.1/8/7/XP. Suitable for connecting computers to various RS485 devices, industrial automation systems, CNC machine tools, and other applications.
