Review: Worked great for connect PC to Maruson UPS, but needs a an adapter cable to plug into female DB9. - This cable allowed me to connect my Maruson UPS to my tower PC. The only bad thing is it come with 2 nuts that are not removable, which cause this cable to not be able to plug into a female DB9, so I had to buy and additional cable to connect the DB9 on the back of the UPS. This double-coversion/online UPS is a "sleeper"... the most inexpensive online UPS that actually works, including having power management software. The worst part is there is no/very little support and it is a bit noisy, but what you get is a UPS that will work with generators for a very good price. It comes with a USB-to-DB9 cable but that didn't work. My tower PC never detected it when plugged in. So I found that I needed 2 additional cables: https://www.desertcart.com/dp/B00A6GIUZA https://www.desertcart.com/dp/B00AHYJWWG The 2nd one is the main electronic conversion cable but for some reason it has screw blocks that prevent from plugging into the back of the UPS, so I had to buy the 1st one to adapt it so it could connect to the DB9 at the back of the UPS. Then I got the Winpower G2 software working on Windows 10 (for some reason Maruson buries the link, so you have to View source on their web page and find the download link). It took me a while to get the G2 software to find the UPS (the documentation is bad), but I think what made it work is there is a button that allows you to download a license and then you have to import the license file. After that the G2 software was able to find the UPS (in my case on COM7 port), and it is actually pretty nice. So it takes a bit of work to get everything working, but this is a helluva deal. I've already had one "event" where we lost main power, and it takes about a minute for the generator to kick in, but this UPS kept my tower running fine. https://www.desertcart.com/dp/B00A6GIUZA Review: What is shipped is exactly what is advertised & arrived when they said it would! - Works great ## Features - [ USB to RS-232 Serial Adapter ] : 5ft Cable Length - Easily connect legacy DB-9 serial devices to modern USB-equipped computers.

It works with Win 8, but my tablet is only 32. **Q: Does it come with compatible driver for W8-64bit? If not, where do I get the driver from?** A: It comes with a driver compatible with Windows XP through 10 (Including Vista, 7, 8, 8.1, etc) both 32 & 64bit. If the driver included on the CD does not work, Windows usually can install the newest driver on its own (through Windows Update) and the latest is also available from the manufacture's website. **Q: Does this unit work for communication with CNC machines for file transfer and DNC ?** A: It works great with siemens 3n, 880n, and 840d controls for me. I have used win7, win8 and win 10. Comes with driver cd, but windows finds and installs drivers automatically.. Great solution for me **Q: How long is the cable?** A: I don't have it with me right now to measure but it is quite long, my guess is about 5-6 feet long. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked great for connect PC to Maruson UPS, but needs a an adapter cable to plug into female DB9. *by J***L on June 30, 2025* This cable allowed me to connect my Maruson UPS to my tower PC.
