USB to RS232/DB9 Cable

Works well with Linux

Good quality .

Use with 2 laptops - one Windows 10, one Windows 11. I plugged the adapter into a USB port on each laptop in turn and each one recognized the adapter instantly. Going to Device Manager I found that the adapter appeared as COM3, 9600,8,N,1 on both machines. Was able to re-assign the port number to what I needed without any problem. I did not need the included CD to set up and use the device. HOWEVER when I went to plug the male end on the adapter into the female socket on the device I was connecting I discovered that the 9-pin RS-232 plug on the adapter has FEMALE screw sockets instead of male screws to attach it with. It was impossible to plug the adapter into the female receptacle on the device I was trying to connect. This is stupid. RS-232 has been around forever, and the MALE end should have the screw connectors and the FEMALE end have the screw sockets. I had to use an RS-232 extension cable in order to connect the adapter to the device.

This again was old school technology use, use to use Rs-232 to RS-232. No longer can on windows 11 so needed USB worked as advertised.

Good quality

I needed a USB to RS-232 Male serial cable for some programming at my job. My initial thoughts when unpacking the cable and seeing a CD to install drivers was, great another piece of software on my laptop that is already loaded with work software. Because I did not want to install another driver on my laptop, I decided to try the cable without installing the drivers and it worked without an issue. This is not to say there may be devices that communicate better with the proper drivers installed, but for my use, it was plug and play. I was using Windows 10 as the operating system. You will most likely need to install drivers to work on older operating systems. Overall the quality of the cable is exceptional and exceeded my expectations. Great cable for the price!

I have purchased these - they came with the PL-2303 chip inside and work just fine on my Mac, both M1 and M2. Also on my PC (windows 10). However I purchased 1 recently and it is not recognized by my Mac (M2). It does work on my PC, but the mac won't recognize it. Downloading the newest drivers didn't change that. From the Macs System Information/USB listing... the old, working version of this cable shows a Product ID of 0x2303, vendor Prolific. This new, non-working cable, shows up as Product ID 23a3, vendor = Prolific. I'm guessing the product ID is not matching the driver for some reason. I've done some searching around the internet and haven't seen any references to this.... other than the general advice to get an FTDI chip cable and not use the 2303 cable. The product information does not mention this issue - everything just says compatible with Mac.

Doesn't work with windows 11. Tried downloading drivers from the website, but no success. Ended up buying TRENDnet USB to Serial 9-Pin Converter Cable, Connect a RS-232 Serial Device to a USB 2.0 and it worked perfectly no need to install any extra drivers with Windows 11.

Used to connect a vintage Palm PDA to a modern computer that only has USB ports, worked fine. Also tested the additional signals (such as CTS/RTS and so on) using a terminal program, these seem to work as well. Decent product overall.

古いネームランドのリンクケーブルはRS232Cなので、変換用に購入しました。 すでに別の変換ケーブルは持っているのですが、固定用のメスネジ付きが気に入って追加購入。しっかり固定できて良いです。 Windows11できちんと認識し、ProfiIicのドライバがインストールされました。 ネームランドとの接続は別のケーブル同様、COM4からCOM1へ変更しないと動作しないのも同じ。 安定した動作で満足してます。

excellent cable if you are looking for a REAL RS 232 signal to USB convertor

Super kabel van goed materiaal en maakt gebruik van de Prolific PL2303GT chip. Werkt goed op Windows 7 tot er met 11!!! Wordt met automatische update voorzien van de juiste driver! Op diverse apparaten getest en werkt uitstekend:)

conforme et fonctionne sans problème, bonne qualité
