I have used older versions with older Prolific chips. This one is head and shoulders above them. I have an old GCC Mercury I laser engraver. I usually prefer using a parallel cable because in the past my experience with the USB232 port was extremely slow compared to the parallel port. The files I sent at 56Kbps were uploaded very quickly. I bought this for a backup in case I have problems with the parallel port or to use on computers that have neither port. I am happy enough with this cable to use it without considering it a second choice. I set this adapter to COM 1, 56700bps, 8 bit, 1 stop bit, no handshake.--whatever the default is, just changing the bps speed from 9600bps; with the GCC Mercury I, and similar lasers, you also need a null modem adapter at the laser, so this cable needs a DB9 F to DB25 M adapter: https://www.desertcart.com/dp/B00066HOWK, and and a null modem cross over DB9-Female to DB9 Male at the DB9 end of the USB to DB9 adapter. Or you can use a DB25 Female to DB25 male null modem crossover at the end of the DB9 to DB25 adapter mentioned above. If you are handy with you can look up the 8 or 9 wire connections and make your own null modem adapter. My installation is using a 32 bit installation of Windows 10 x86 (32 bit--must be installed on an MBR drive--there is no W11x86 version because of the UEFI requirement). W10 32 bit is way more stable and useful than Windows 7 32 bit or XP at this point. The 32 bit drivers from GCC have not been updated since around 2009, nor will they ever be, and you have to use Windows 32 bit in order for the driver to work. My old Mercury I still engraves and cuts like a charm. New machines of that quality are considerably more expensive now. UPDATE: I also purchased the 3 foot version of this cable, along with a micro DB9 Null Modem adapter from Arnorin, and a final one foot DB9 F to DB25 M to interface with the laser engraver. This setup causes less stress on the laser machine's DB25 connector and less length, so less voltage drop and weight. Review: Great quality, may require driver download from site - I purchased I bought another Sabrent brand DB9 to USB cable converter that had the screw stems in the male connector that blocked the connector itself to seat into my Crestron AudioVisual Processor. This cable did the job perfectly, albeit there was a small hiccup due to the usb not recognizing the conversion due to drivers oddly enough. Typically Windows is able to detect and automatically obtain the right firmware/drivers to allow data transmission, but in this case I just went to UGREEN's website and downloaded the appropriate driver and now it works flawlessly. As for physical aspect of the cable, it is a very rugged and quality looking cable with some decent weight from the gold-plated materials they use. The cable is packaged in a simple packaging box with the UGREEN logo and a picture of the cable on the front. The cable is contained in a clear plastic wrap, you can tell where they cut costs to advertise at the price it is, but certainly not to the point of some packaging I've seen other companies do. And for something like a simple cable where the R & D matter most I'm not complaining. Highly recommend this product for anyone working with older network or AV gear that don't have USB or ethernet console access. ## Features - Easy to Use: The serial to usb adapter can be connected to serial device via USB port.

It came with a cd with necessary driver to use this cord with my Windows 10 Toshiba laptop. I purchased this cord because we got my a Signtronix led sign and it requires to be programmed via a serial connection on the sign itself. Considering we live in today's world my 1 - 2 year old laptop does not have a serial port so I needed to find a usb to serial cord. I was hoping this would work with sign since the factory cord and usb adapter wasn't with the sign when we got it 2nd hand. After installing the driver and connecting everyrhing this usb to serial cord allowed my computer to communicate with the sign so I could use Signtronix software to program it. Overall, this cord seems like it is of good quality and it worked as intended. I am happy customer. ## Frequently Bought Together - UGREEN 6ft USB to Serial Adapter, Serial to USB Adapter DB9 Male 9 Pin with PL2303 Chipset, PVC Jacket, RS232 to USB Cable for Windows 11 10 8.1 8 7 XP Vista, Mac OS, Linux - SABRENT 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) - OIKWAN USB to RS232, USB Serial Adapter with FTDI Chipset,USB 2.0 to Male DB9 Serial Cable for Windows 11,10, 8, 7, Vista, XP, 2000, Linux and Mac OS(6ft)… --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/14374604-ugreen-6ft-usb-to-serial-adapter-serial-to-usb-adapter](https://www.desertcart.pt/products/14374604-ugreen-6ft-usb-to-serial-adapter-serial-to-usb-adapter) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
