The other system is driver-free.) Original Prolific Built with the prolific Chipset, Provide more reliable and more compatible performance than competing products Product Parameters Abundant USB Serial Cable USB Serial Cable 1M USB Serial Cable 2M USB Serial Cable 3M Bluetooth 5.3 Adapter Review: It's a serial cable, it works! - Hmm, not much to say here. It works perfectly fine out of the box on Linux (not a given) so I doubt you'll have problems on Windows, maybe on Mac. Zero problems at all, does what it needs to - convert RS232 serial to USB. Have been using this with my Zoom dialup modem for tinkering but can be used for other things, such as connecting to the serial consoles of networking devices. Cheap and cheerful, and perfectly functional to boot. Review: Working with Linux, Virtualbox and Windows XP/7 - It is functioning nicely as a means of controlling my NIR spectrometer via the spectrometer's parallel D25 serial connection, using a D25 to D9 serial adapter. My PC lacks the now scarce D9 serial port, so a USB to Serial D9 cable represents my only option. This Ugreen cable has a chip inside, in order for it to be recognised by Ubuntu 20.04 linux OS, which it is, natively. The NIR spectrometer software requires Windows XP or Windows 7 but a Virtualbox virtual machine (VM) runs both Windows OS's as guest OS's under Ubuntu 20.04 LTS host OS. This cable enables a serial connection on Virtualbox as serial host machine (not host pipe). Select the dummy guest Windows COM port, IRQ and address and save. Be sure to allow all users read access to the USB serial host device in a linux terminal, using: " sudo chmod 666 /dev/ttyUSB0". After setting up the VMs and configuring the serial connection it worked very well. I would have opted for a longer cable than the one metre length, had this been an option, but a Ugreen USB male to female extension cable privided the necessary reach from PC on my desk to table with NIR spectrometer. Overall a very useful cable indeed. ## Features - HOW IT WORKS: Ugreen USB to RS232 DB9 Serial Adapter is designed for connecting to serial devices such as DB9 equipped serial modems, ISDN Terminal Adapters, digital cameras, label writers, palm PCs, barcode scanners, PDAs etc through USB port with 1Mbps data transfer rate - CONNECTORS: Features a standard USB Type-A Male to a standard 9-pin D-Sub 9 RS-232 serial connector. - CONDUCTOR & SHIELDING: Tinned Copper Conductor(Wire guage#24#28) and triple shielding ensure the best data transfer rate. Powered by USB port, no external power adapter required. Simple installation, plug & play after one time driver installation - What You Get: USB 2.0 to Serial (9-Pin) DB-9 RS-232 Converter Cable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00QUZY4WO | | Best Sellers Rank | 1,749 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 1 in Serial Cables | | Brand | UGREEN | | Brand Name | UGREEN | | Colour | grey | | Compatible Devices | Cash register, printer, scanner, barcode printer | | Compatible devices | Cash register, printer, scanner, barcode printer | | Connector Type | USB Type A | | Connector type | USB Type A | | Country of Origin | China | | Current Rating | 2 Amps | | Customer Reviews | 4.6 out of 5 stars 9,237 Reviews | | External Testing Certification | 177202201739 | | Global Trade Identification Number | 06957303822225 | | Item Dimensions | 200 x 2 x 3 centimetres | | Item Weight | 0.12 Kilograms | | Item dimensions L x W x H | 200 x 2 x 3 centimetres | | Manufacturer | Ugreen Group Limited | | Manufacturer Part Number | 20222 | | Model Number | 20222 | | Nominal Power | 2 Watts | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Product Finish Type | Glossy | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | Router, Modem, Inverter, Control Devices, Oscilloscope, Cash Register, Telescope, Labeling Machine, Barcode Reader, Home Alarm, POS, PDA, PABX | | Specific uses for product | Router, Modem, Inverter, Control Devices, Oscilloscope, Cash Register, Telescope, Labeling Machine, Barcode Reader, Home Alarm, POS, PDA, PABX Specific uses for product Router, Modem, Inverter, Control Devices, Oscilloscope, Cash Register, Telescope, Labeling Machine, Barcode Reader, Home Alarm, POS, PDA, PABX See more | | Unit Count | 1 Count | | Warranty Type | Limited | ## Product Details - **Brand:** UGREEN - **Cable type:** USB - **Compatible devices:** Cash register, printer, scanner, barcode printer - **Connector type:** USB Type A - **Special feature:** Data Transfer ## Images ![UGREEN USB Serial Cable USB to RS232 DB9 9 pin Converter Cable for Connecting Cisco Routers and Switches,Celestron Telescope Nexstar hand Controller, Extron Crestron Products with PL2303 Chipset (2m) - Image 1](https://m.media-amazon.com/images/I/61N0K3md5nL.jpg) ![UGREEN USB Serial Cable USB to RS232 DB9 9 pin Converter Cable for Connecting Cisco Routers and Switches,Celestron Telescope Nexstar hand Controller, Extron Crestron Products with PL2303 Chipset (2m) - Image 2](https://m.media-amazon.com/images/I/613lE71jQyL.jpg) ![UGREEN USB Serial Cable USB to RS232 DB9 9 pin Converter Cable for Connecting Cisco Routers and Switches,Celestron Telescope Nexstar hand Controller, Extron Crestron Products with PL2303 Chipset (2m) - Image 3](https://m.media-amazon.com/images/I/610CV2hI42L.jpg) ![UGREEN USB Serial Cable USB to RS232 DB9 9 pin Converter Cable for Connecting Cisco Routers and Switches,Celestron Telescope Nexstar hand Controller, Extron Crestron Products with PL2303 Chipset (2m) - Image 4](https://m.media-amazon.com/images/I/71QGCZC1cJL.jpg) ![UGREEN USB Serial Cable USB to RS232 DB9 9 pin Converter Cable for Connecting Cisco Routers and Switches,Celestron Telescope Nexstar hand Controller, Extron Crestron Products with PL2303 Chipset (2m) - Image 5](https://m.media-amazon.com/images/I/71cpqtIi6AL.jpg) ## Available Options This product comes in different **Item Display Length** options. ## Questions & Answers **Q: does this work with a microsoft surface?** A: Hi Mr.M, it would work well Win10/8.1/8 with PL2302 chipset, if your system is windows RT, you need to chose this cable with FTDI chipset.ASIN B00QUZY4L0. **Q: will this work with windows 10** A: Yes. I have just tried by installing the Windows 8 drivers from the included mini-disc of drivers, and connecting it to my elderly Garmin E-Trex H. I was using the GPS to enter my site coordinates into a planetarium software programme and it worked just fine. This was using a laptop previously running 8.1 and recently upgraded to Windows 10. To my inexperienced eye it appears to be a well made cable which I bought specifically for W 8.1 but am delighted to discover that it also works with W10. Hope this helps. **Q: Hi, does this work with cisco products?** A: it dosent work with all cisco. routers ok switches not so much. better off getting startec one with ftdi chipset, that one definatly works. had to junk this one **Q: Does it work on linux?** A: Yes, It work well with Linux.Carol ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's a serial cable, it works! *by V***I on 21 January 2025* Hmm, not much to say here.
