USB 2.0 to Serial (9 Pin) DB 9 RS 232 Converter Cable, Prolific Chipset, HEXNUTS, [Windows 11/10/8.1/8/7/VISTA/XP, Mac OS X 10.6 and Above] 2.5 Feet (CB-DB9P)

It works! I successfully used this cable and picocom on linux to connect to an old tektronix oscilloscope and enable some locked features. Happy with the purchase.

Works exellent

The cable works as intended. Money well spent...

Works fine

Just what I needed to access the console connection of a network switch (Extreme Networks Summit X460-G2). On two Windows 10 PCs this adapter cable was automatically recognized for what it was, driver installed automatically and a COM3 port became available. I used this with a serial to RJ45 cable, the needed connection to the switch. A good thing too since this adapter cable is rather short to make such connections by itself. The “serial” end lights up to visually confirm the USB connection. Commentary: it’s a shame that still today I’m using a text-based serial port console connection to configure high-end devices. Why, for the price, the higher end devices don’t include a nothing-else-required complete web-based configuration. It’s stupid to need to learn the precise command line language just to set up such equipment. And that kills the possibility of remote support, instead needing to drive to a location to connect to the console port. Or go cheaper brands that include a FULL GUI web configuration - makes little sense!

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.

Works fine on a M2 Mac running Sonoma and a Windows 10 box. Windows worked out of the box. Drivers from the Internet for the Mac didn't work, but I eventually learned that Prolific publishes their drivers on the App Store. Drivers come on CD, but who has a CD anymore? Biggest problem is that the cable has female nuts to mate to the thing you're plugging it into. However, devices typically also have female nuts and expect the cable to have the male screws. So I couldn't plug this into my device. I couldn't remove the nuts from the cable so I had to pull them from the device. So now it plugs in but isn't clamped by anything.

This is a great option for connecting to Legacy GE drives that require a 9 pin Din to establish a connection to the drive. My new laptop doesn't have a serial port. This option allows me to utilize the USB port as a serial port.

Laut Internetrecherchen gibts wohl 2 dominierende Chips für RS232-Anbindung. Den "guten" und den "nicht so guten". Der Nicht-so-Gute, so einen hatte ich wohl bisher. Ich kann von einem SICK CLV612 Scanner (den wir in der Arbeit einsetzten, ist ein Industrie-Barcode-Leser) zwar daten Lesen, aber es ist unmöglich eine Verbindung zum Scanner aufzubauen, also den Scanner anzufunken. Da passen die Pegel nicht, die Signalflanken, es fehlen Steuersignale, was weiß ich, es geht nicht. Hier diesen über Amazon-Vine geschossen, der funktioniert auf Anhieb einwandfrei. Und er blockiert mir keinen USB-A-Port, wo die Funkdongel von Tastatur und 3D-Maus wohnen... Workstation hat leider nicht mehr Ports für USB-A, aber USB-C war noch frei. Also mir passts.

Fonctionne parfait, la prise db9 male s'allume lorsqu'elle est alimentée en usb

yanında gelen CD deki uygulamayı kurunca usb port seriale dönüşüyor. kaliteli ürün

全く問題なく使えています。 よくある変換ケーブルはネジで止められない物が多いですが、この商品はしっかりねじ止めできるので、しっかりと繋がって安心感があります。

説明通りMac2012highsierraで使えました。
