USB 2.0 dual RS232 adapter cable

This USB 2.0 cable adds two DB9 male serial ports to a single Type-A port. It targets engineers and technicians who must connect CNC machines, industrial sensors, barcode scanners or similar legacy equipment to modern laptops. The PL2303TA and FS232A chipsets provide broad OS coverage including Windows, Mac OS 8/9/X 10.6+ and Linux. No external power supply is needed because the adapter draws power from the USB port.

Before ordering check your ports and OS

Verify the host computer has a free USB 2.0 Type-A socket and that the serial devices use standard 9-pin DB9 male connectors with hex jack nuts. Driverless operation works on Windows 10 and 8.1; older Windows versions and Mac or Linux require a one-time driver install. The cable supports programmable baud rates from 75 to 128000 bps and serial throughput up to 250 Kbps, so confirm your equipment matches those limits.

Nuts shielding and driverless convenience

Each DB9 connector includes hex jack nuts that lock the cable securely to panel-mounted equipment, preventing accidental disconnects in industrial settings. Triple shielding plus tinned copper conductors protect data integrity over the full cable length. The driverless experience on current Windows saves setup time, while the single USB connection eliminates the need for a separate power adapter.
