USB-C to DB9 Serial RS-232 Adapter Cable 6FT, Prolific PL2303GS Chipset, USB 2.0, 1bps-12Mbps Baud Rate, for POS Terminals, Modems, GPS, Industrial Devices (CB-D9C6)

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.

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 exellent

Purchased this to connect a scale to a Window 11 PC. Does not come with any instructions. Could not find it in the device manager so I needed to contact customer support. We were able to get it workings.

Very good serial adapter. I've never seen one of these fail. Handles everything ive thrown at it. Would be nice to include a null-modem and genderbender but whatever.

recognized by Win10, setup right, easy to configure

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.

Years ago, serial cables were a dime a dozen and every PC and some laptops had a serial port. USB basically made the serial port obsolete for most devices except networking devices like switches and routers. Most switches in the past few years come with a micro USB or USB-C management port in addition to an RJ45 jack for a serial cable. I've found the USB connections to be hit or miss. But a serial cable always works. I have a TP-Link SG3428 switch that I needed to reset the password for so it could be adopted by an Omada controller. Most layer 2/3 switches don't have a reset button you can press, so you need to console in and do it from the bios. Used this adapter along with the RJ45 to serial port cable the switch came with and it worked perfectly. You will need to load the drivers for the cable as it has a chip in it. But the adapter comes with a driver CD. Ironically, that presents another problem as no PCs or laptops come with a CD drive anymore. But my personal PC at home has multiple disc drives so wasn't an issue for me. This cable just works, no issues. Highly recommended.

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。
