Newer ZK-U485 revisions use the CP2102 chip from Silicon Labs. Download the official CP210x Universal Windows Driver from silabs.com.
To use the device, you must first install the correct communication driver to create a virtual COM port on your system. : Windows 10 & 11 : Universal Windows Driver. Windows 7, 8, 10 : VCP Windows Driver. Legacy (XP & Vista) : Win2K/XP/Vista Driver. Hardware Setup : Plug the converter into a USB port.
Automatically identifies and controls the data transmission direction without requiring handshake signals (like RTS or DTR) or jumper settings Communication Range: Supports distances up to 1200 meters (at 9600 bps) Transmission Speeds: Supports baud rates up to 115200 bps zk-u485 driver
. It is a "pure hardware" device, meaning it is not limited by specific communication protocols and supports standard half-duplex RS485 communication Core Technical Features Main Controller Chip: Utilizes the chip for reliable USB-to-serial conversion Protection Suite: Features industrial-grade safeguards including TVS transient suppression electrostatic ESD protection surge protection short-circuit protection for both signal lines and power Automatic Data Flow Control:
The physical board integrates built-in safety features, including , ESD electrostatic protection, surge protection, and short-circuit protection across the A/B signal lines. This prevents voltage spikes from destroying the host computer's motherboard during industrial field testing. Step-by-Step Driver Installation Guide Newer ZK-U485 revisions use the CP2102 chip from
