A: A one-time driver installation is required before the first use. After that, the system recognises the device automatically every time it's plugged in. The driver can be downloaded directly from the Prolific website. Q: Can it connect a barcode scanner with a DB9 port to a modern office PC that only has USB? A: Yes, that's exactly what it's designed for. It bridges DB9 Serial devices — including barcode scanners, label printers, and modems — to any standard USB port on a modern computer. Q: Does it work on a MacBook — which macOS versions are supported? A: It supports Mac OS X 10.6 and above. For the latest macOS versions, downloading the most current driver from Prolific's website directly is recommended to ensure full compatibility. Q: Is 1Mbps fast enough for industrial equipment — or will it slow down operations? A: More than fast enough. Most RS-232 Serial devices operate well below 1Mbps — that ceiling is very high by Serial communication standards and won't create any bottleneck in typical industrial or office environments. Q: Can it be used through a USB Hub — or does it have to plug directly into the computer? A: Plugging directly into the computer's USB port is recommended for the most stable connection. If a hub is necessary, choose one with its own power adapter to ensure sufficient and steady voltage. For offices and factories that still rely on legacy Serial equipment alongside modern computers, the right adapter makes the difference between downtime and seamless operation.
