Antaira UTS-402CK 2-Port RS-232/422/485 to USB 2.0 Converter, Optional Isolation

The UTS-402CK from Antaira Technologies is a high-speed 2-port RS-232, RS-422, and RS-485 to USB 2.0 serial adapter. It was designed to connect legacy serial-based hardware to computers, thin clients, and servers that lack serial ports. It provides instant serial port expansion over the Universal Serial Bus (USB). The locking screw connectors for the upstream (USB type B) cable and DB-9 connectors prevent accidental disconnection. Built for industrial settings, the UTS-402CK features a rugged metal case and mounting flanges. The isolation option (UTS-402CK-SI) offers surge protection for electrically noisy locations.

The plug-and-play software makes installation effortless. Fasten the cables and follow the steps of the software wizard. Your system will recognize the device and install the drivers automatically.
