Product Description

Plugable USB to Serial Adapter infographic showing possible uses

Easily add an RS-232 9-pin serial port to any computer with our PL2303-DB9 USB to Serial Adapter!

This adapter will let you connect older serial devices to modern computers, for terminal services, data transferring, remote control, and programming. Supports baud rates from 75bps to 12Mbps, multiple stop bit and parity types.

Connect legacy RS-232 serial devices to any modern computer

Plugable's USB to Serial Adapter features Prolific's PL-2303HX Rev D chip for the best combination of support and performance with a wide range of RS-232 serial devices. Drivers are built-into Windows 11, 10, 8.x, 7, and most Linux distributions, drivers are available for Windows XP, Vista, and macOS.

Connector compatibility note

This adapter replaces a legacy built-in or PCI serial port and features a fixed male port with screw in connection. For connecting devices that also have a male connector an inexpensive DB9 coupler or standard serial cable can be purchased separately.

Compatibility

Works with devices with RS-232 serial ports such as other PCs with RS-232 ports, Bluetooth serial adapters, telescopes, amateur radio gear, GPS receivers, routers, firewalls, modems, plotters, embedded character displays, scan tools, sonar units, embedded boards and many others. Works with software like: HyperTerminal, TeraTerm, WinDBG, all open source serial software on Linux, etc.

Genuine

We use only genuine Prolific serial chipsets in our adapter. Some inexpensive serial adapters use cloned Prolific serial chipsets that will not work with the latest Prolific drivers, both those available for download and the drivers embedded in Windows. Because we only use genuine Prolific chips, our adapter is always compatible with the latest drivers from Prolific.

Worked with Windows 11 with zero configuration required. Losing one star as it costs 70% more than the older ones not compatible with Windows 11.

Watch out for connection type

Reviewed in the United Kingdom 🇬🇧 on 30 December 2022

Verified Purchase

If the thing you're connecting to has screws, this will be perfect. Mine had nuts - just like on the end of the connector so the pins wouldn't reach the socket. Luckily, it was possible to prise the casing apart without breaking it. Then my husband drilled the nuts out for me and the casing snapped back on easily, so I have a fully functioning adapter. My laptop wouldn't immediately recognise the driver, but after re-installing it and restarting the computer, it worked perfectly. The support from the suppliers was very quick but, obviously, they could only tell me they didn't make adapters with pins and couldn't advise me to drill out the offending nuts!

Works well but watch out for the retaining nuts

Reviewed in the United Kingdom 🇬🇧 on 20 August 2013

Verified Purchase

Having just put in a Solar Edge Inverter, I found that the only effective way to connect it to my Windows XP laptop is via the RS232 port on the Inverter. As my laptop does not have a built in serial port, I decided to try this cable.

I followed the instructions and installed the drivers onto my Dell Vostro laptop prior to plugging in the USB end of the cable. I then plugged in the USB plug and XP immediately recognised it. From then on, I just had to connect the other end up to the inverter and I was away. Apart from my problem explained below, everything worked as I hoped.

So first the good news, it worked perfectly & first time. I haven't tried it with Windows 7 or 8 but the driver information says it will work with those operating systems as well. Plugable Technologies even sent me an email before the cable had arrived to point me to the latest drivers on the web site.

The bad news is that the two nuts on the RS232 end of the cable are female. The plug pins are male but the two retaining nuts are female (effectively mimicking the serial ports you used to get on PCs & laptops). In my case, the socket on the Inverter is female (as expected) but it also has female retaining nuts.

The end result is that you can't actually plug the cable in to the inverter because the retaining nuts prevent the two ends from plugging into each other. Unfortunately, you can't remove the nuts from the cable either. In the end I had to remove the nuts on the Inverter socket which then allowed me to plug the cable in (although I nearly lost the socket inside the inverter in the process!)

I have ordered a straight wired male to female RS232 cable which I hope will resolve the problem. If it does then I will update this review to indicate which one I bought.

UPDATE : The straight wired male to female RS232 cable works a charm and has solved my issue. For anyone in the same predicament, it is a 'Serial RS232 9 pin Connection Cable, Male to Female, 1.8 Meter (6ft)' which I bought from Amazon for the 'princely' sum of £3.59. Well worth it. Just make sure you buy a 'straight wired' cable and not one which has the words 'null modem' in the description.

This has the standard prolific chipset which is arguably one of the most compatible and stable usb to serial UARTS. Does the job perfectly.

Works a treat

Reviewed in the United Kingdom 🇬🇧 on 24 May 2022

Not usually one to write reviews. Had many of these USB to serial adapters in the past. First time using one on windows 10 and checking out the webpage for the drivers, it automatically installs the drivers it said. Bit skeptical but right enough it done exactly that.
I’m a controls engineer so this is a must have tool. Working perfectly.

Quality Counts

Reviewed in the United Kingdom 🇬🇧 on 31 August 2015

Verified Purchase

This beauty has just saved me £150!

I needed an adapter to connect the GoTo hand controller for my computerised telescope to my computer in order to update the firmware. I tried this using a cheaper adapter that have had for a while and found the update never reached more than 30% before failing. Worse still, the part update seemed to have killed my handset and they cost £150 to replace.

Luckily I managed to get enough life out of the handset to attempt a firmware upgrade using the Plugable cable. It worked first time and my handset now seems to be functioning properly.

I guess everyone who looks to buy one of these will have their own use in mind but the point of my review is: This is an exceptionally well made cable adapter. Very sturdy and good quality. It screws on to my 9 pin female port to create a secure link. Most importantly it allows for a very fast transfer rate of data which is just what I needed.

I am very pleased with everything about this purchase, from the speed of delivery to the quality of the product. You get what you pay for. Highly recommended if you need a way to connect a 9 pin port to a modern computer via the USB.

A very useful bit of kit

Reviewed in the United Kingdom 🇬🇧 on 11 May 2014

Verified Purchase

I don't forever chase the latest technology. To my mind, it doesn't matter how old something is, if it works and does the job then why replace it? This can be a problem with computers where, for some obtuse reason, the industry decides to abandon formats that have been a worldwide standard for decades. Standards such as RS-232 Communications and LPT Parallel Ports in favour of USB. I have a perfectly good Olympus digital camera but found - when I had to replace my PC - that with no serial port I could no longer download any of the photographs. This is where this USB to RS-232 DB9 Serial Adapter became essential. I did already have one of these adapters, but again, time marches on, technology changes, and the chipset in the one I had would not work with Windows 8.1. This one from Plugable Technologies is perfect. Just plugged it in, Windows 8.1 found a driver, connected the camera and hey presto - I was back in business. No fuss, no hassle, minimal cost and I don't now have to replace a £200 camera for want of the correct cable and socket!
