Value for money

Nice

Very good and useful product. Male and female connections are not as snug fit as needed. They fit slightly loose.

just took loopback test. Not used on Modbus communications yet. works in windows 7. automatically downloaded drivers.

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.

Buen producto, Funciona Ok con win 11.

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。
