3-Foot USB to RS232 Serial Cable with Prolific PL2303 Chipset, DB9 Male Connector, COM Port Retention, 512-Byte FIFO, and Screw-Lock Mounting for IT and Industrial Serial Communication
The StarTech 1P3FPC-USB-SERIAL is a 3-foot (91 cm) USB to RS232 serial cable that adds a DB9 COM port to any computer through USB-A, bridging modern systems to legacy serial devices in IT, industrial, POS, and laboratory environments. The Prolific PL2303 chipset delivers reliable communication at baud rates up to 921.6 Kbps with a 512-byte FIFO buffer, supporting 5/6/7/8 data bits and five parity modes for broad serial protocol compatibility across equipment generations.
COM port retention automatically preserves the assigned port number through cable disconnections and system reboots, maintaining stable configurations for serial applications that reference specific COM port assignments. The screw-lock nuts on the DB9 male connector secure the adapter to serial peripherals for vibration-resistant connections in server rooms, factory floors, and mobile deployments. Plug-and-play drivers install automatically on Windows, macOS, and Linux, with no additional software or configuration required to establish the serial link.
Where the StarTech RS232 Cable Fits
- IT infrastructure requiring serial console access to network switches, routers, and servers where the 3-foot cable length reaches rack-mounted equipment from a nearby workstation, COM retention preserves port assignments across reboots, and the Prolific PL2303 chipset provides broad device compatibility
- Industrial control and automation environments connecting PLCs, sensors, and instrumentation where the 921.6 Kbps throughput with 512-byte FIFO handles high-speed data acquisition, screw-lock mounting prevents accidental disconnection on vibrating equipment, and support for 5/6/7/8 data bits accommodates older industrial protocols
- Retail POS and medical/laboratory deployments with barcode scanners, receipt printers, and measurement devices where plug-and-play compatibility across Windows, macOS, and Linux eliminates driver complexity, and COM retention ensures serial applications reconnect to the same port after power cycles without manual reconfiguration
What the StarTech RS232 Cable Delivers
- Prolific PL2303 with 921.6 Kbps Throughput: Prolific chipset delivers reliable serial communication at baud rates up to 921.6 Kbps with a 512-byte FIFO buffer, supporting 5/6/7/8 data bits and five parity modes (Odd/Even/Mark/Space/None) for broad protocol compatibility.
- COM Port Retention Across Reboots: Automatically preserves the assigned COM port number through cable disconnections, reconnections, and system restarts, ensuring serial applications maintain their configured port assignments without manual intervention.
- Screw-Lock DB9 Mounting: Screw-lock nuts on the DB9 male connector secure the adapter to serial devices for vibration-resistant connections that withstand movement and accidental cable pulls in server rooms, factory floors, and field deployments.
- Cross-Platform Plug-and-Play: Automatic driver installation on Windows, macOS, and Linux provides immediate serial connectivity from the USB-A port without manual driver downloads or configuration steps, compatible with USB 2.0 and earlier USB revisions.
- Broad Device Compatibility: Connects to barcode readers, network switches, receipt printers, PLCs, medical devices, oscilloscopes, scales, and other RS232 serial peripherals through the standard DB9 male connector with screw-lock retention.
