Check the vendor properties, or look directly at the physical chip on the board if the casing is transparent. Step-by-Step Driver Installation Guide
The ZK-U485 features terminal blocks labeled A+ and B- (sometimes labeled TR+ and TR-). Ensure A+ connects to A+ on your client device, and B- connects to B-. If communication still fails, try swapping them temporarily; some manufacturers invert the A and B lettering on their equipment. You should see "USB-SERIAL CH340 (COMx)," where x
The ZK-U485 driver is integrated into the Linux kernel. In most cases, the converter works with no extra steps.
The ZK-U485 is a compact module that converts serial data from USB (Type-A) to a 2-wire half-duplex RS485 (terminal block) interface. It is often used for: Connecting PLCs to a computer. Communicating with motor drives (VFDs). Data acquisition from sensors (Modbus RTU). Building automation systems.
