Is the BENFEI USB to Serial Cable the straightforward solution for workshop and office use?
⚡ At a Glance
- • Data Transfer: Supports up to 1Mbps serial transfer and full RS-232 signal set including CTS/RTS
- • Best for: Technicians, engineers and hobbyists connecting legacy modems, scanners and controllers
- • Not ideal for: Devices that require native USB-C ports without an adapter
Uses a Prolific PL-2303 chipset for broad operating system compatibility. Tinned copper conductors with triple shielding help maintain reliable 1Mbps RS-232 transfers.
Reliable serial connectivity - with Prolific PL-2303 chipset
Prolific PL-2303 chipset handles the USB to RS-232 conversion and is recognised by a wide range of operating systems, listing Windows 10/8.1/8/7, Mac OS X 10.6 and above, and Linux 2.4.0 and later. User feedback confirms support for full serial signals including CTS and RTS.
Straightforward connection for legacy modems, barcode scanners and industrial controllers, with stable comms at up to 1Mbps.
Secure, low-interference transfers - with tinned copper conductors and triple shielding
Tinned copper conductors, specified wire gauges #24 and #28, combined with triple shielding reduce electromagnetic interference and preserve signal integrity during serial communication.
Fewer dropouts and less data corruption in electrically noisy environments, useful on shop floors and near point-of-sale equipment.
Simple setup for mixed environments - with USB-powered, plug-and-play after one-time driver installation
Powered directly from the USB port so no external power adapter is required. Requires a one-time driver installation, after which the connection functions as plug-and-play on supported systems.
Quick to deploy with laptops and desktops, making it practical for field service, lab benches and workshop diagnostics.
