Standard USB Type-A to male 9-pin DB9 RS-232 connector with Prolific PL-2303G chipset. USB-powered cable uses tinned copper conductors and triple shielding for dependable data transfer.
Broad compatibility - with Prolific PL-2303G chipset
Prolific PL-2303G drivers support a wide range of operating systems including Windows 11/10/8.1/8/7 and Mac OS X 10.6 or higher, plus many Linux kernels. Driver installation is required once, after which the USB-to-RS232 link behaves like a serial COM port.
Wide OS support makes connecting older serial modems, PDAs and barcode scanners straightforward. Compatible systems reduce time spent hunting for alternative interfaces.
Stable data transfers - with triple shielding and tinned copper conductor
Tinned copper conductors (wire gauge #24 and #28) combined with triple shielding lower electrical interference and preserve signal integrity across the 1.8m cable. Shielding helps maintain consistent 1Mbps throughput in electrically noisy environments.
Fewer transmission errors during label printing or data reads from barcode scanners. Reliable connectivity suits workshop and retail environments where interference can be an issue.
Hassle-free setup and power - with USB bus-powered design
USB port supplies all required power so no separate power adapter is necessary. After a one-time driver installation the serial port appears to the host system ready for standard serial communication.
Quick to deploy on site without extra power bricks, handy for field technicians and quick equipment swaps. Reduces cable clutter and simplifies installation.
