USB-to-Serial Hub for Industrial Integration

The Moxa UPort 1650-8 adds eight serial ports to a host over a single Hi-Speed USB 2.0 link. Each port handles RS-232/422/485 at up to 921.6 kbps with 128-byte FIFO and hardware or software flow control. Drivers for Windows, WinCE and Linux keep COM port numbers consistent across different PCs.

Check Host Interface and Driver Support

Verify the host provides a USB 2.0 Type B port and that the operating system matches the supplied driver set. The fixed-base COM utility sets the initial extended COM port number before deployment. Applications requiring baud rates beyond 921.6 kbps or protocols other than RS-232/422/485 will need a different solution.

Rugged Connectors and Secure Power

A 15N high-retention USB Type B connector resists accidental disconnection in vibration-prone cabinets. Mini DB9 female to terminal-block adapters simplify field wiring without soldering. The locking power cord prevents power loss, while 15 kV ESD protection shields the serial interfaces from transient spikes.
