SABRENT Serial Cable to USB, 9 Pin USB Serial Adapter

Plug and play on my windows 10 laptop - works well, excellent value.

Great product needed this to connect my laptop to my 30 year old car as none of my laptops have serial ports. Works perfectly and easy to install drivers.

Very good. Works with Windows and Linux. Then bought a second one. My old one didn't work with Windows so this is more versatile.

Like that they light up when all is connected. Worked as they should.

I had previously wasted my money buying cheaper RS-232 connectors only to find that I needed 'drivers' to make them work. After many hours of online frustration, failing to find drivers that actually worked, I was forced back to Amazon's search pages. looking for a connector which would work. This one offered a 'prolific' chipset, which, I was assured, contained its own drivers. In any event, it also offered a disc with all necessary software. Spend your money wisely, buy a connector that is going to work! This one did it for me....

As advertised

I bought this cable to connect an old handheld personal organiser to a laptop to see if I could retrieve the data from it and it worked (once I had figured how to find the organiser) which was not automatically recognised being so old. Useful! ...

Unfortunately the drivers (even the latest on the manufacturers website https://sabrent.com/pages/support#Downloads) only mentions up to Catalina 10.15. So had to return the product. Install error is "System Extension Blocked A program tried to load new system extension(s) signed by "Prolific Technology Inc." that need to be updated by the developer." I believe the issue is more around Apple locking down their operating system, rather than a faulty product. So the manufacturer needs to either update drivers, or instruction, or make it clear on Amazon that not all Mac OS versions are supported The product itself felt good quality, so I would imagine it would be great for other operating systems

I purchased this unit because my old USB to RS-232 adapter did not work on Windows 10. The reason for this is that the PL-2303 chip used in most of these devices is created by Prolific, and in an attempt to combat the rampant counterfeit clones, Prolific started to add some features to their chips which the standard drivers on Windows 10 (and 8) now look for. If that feature cannot be found, the driver assumes it is dealing with a counterfeit unit and refuses to work, with Windows Device Manager showing a Prolific USB-to-Serial Comm Port device with a yellow mark, indicating error 10. Very old units, based on the PL-2303 H, HXA and XA chips, unfortunately got caught in the crossfire, as they simply lack the verification feature that was added to combat counterfeiting. This is the reason my very old unit (of 10+ year) refused to work. While this was annoying, I understand Prolific’s desire to combat unscrupulous 3rd parties selling counterfeit chips, claiming to be originals, down to the stamp on the chip. As such I opted to find a new adapter that was based on current chip versions and ended up purchasing this unit. When it arrived (in a nice-looking retail box), I was a little weary that it mentioned drivers being available for download, as this is how vendors using counterfeit units may try to get around the standard Windows 10 drivers not working: they offer a replacement driver, possibly based on the older Prolific one that lacked the counterfeit check. Fortunately, my worry was quickly put at easy when hooked up the adapter, as it was instantaneously recognized as a valid device. I ran Prolific’s utility to check the chip version (PL2303_CheckChipVersion_v1006.exe), as it confirmed the Sabrent USB 2.0 to Serial adapter was equipped with a genuine PL-2303 TA chip. Happy joy! Now for those complaining this unit is “wrong” because it has nuts and not screws: you may be forgetting that this adapter is replacing the DB-9 RS-232 port that used to exist on a computer. Those looked just the same as this adapter, as you were expected to put a male-female serial cable between your PC and the device you were hooking it up to, and those cables has the screws needed to secure both ends. While replacing the nuts with screws may be convenient for those serial devices close enough to the computer that they could plug the adapter straight into it, doing so would make it impossible to securely hook up a configuration with a standard serial cable. An option could be for Sabrent to make the screws removable, which would be the best of both worlds, but their existing design is in no way wrong.

Produit de très bonne qualité et 100 % compatible Windows 11 qui le reconnait immédiatement ! C'est une puce PL2303GS.

One of the Good Products i Purchased

Muy bueno

Win10でのCisco機器コンソール接続用に購入しました。 特に問題無く利用出来ています。 安価ですので、保守作業を生業としている人には予備として購入しておくと良いかと思います。
