Gearmo USB to Serial RS-232 Adapter with LED Indicators, FTDI Chipset, Supports Windows 11/10/8.1/8/7/, Mac OS X 10.6 and Above

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.amazon.com/dp/B00A6GIUZAhttps://www.amazon.com/dp/B00AHYJWWGThe 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.amazon.com/dp/B00A6GIUZA

Wasn’t sure if it would work on the Mac, but lo and behold it did. Perfect console cable.

Worked great for connecting my Windows 11 laptop to an ACP SU5000RMXLT5U UPS. Plugged in the adapter, the laptop beeped acknowledging the connection, and then I linked to the UPS to change some setting and monitor performance. No special driver was needed. Just what ever was on the factory laptop.

el producto es buenisimo, me encanto y es tal como en la descripcion

Liked the visual signaling led feature. Used for Laptop without a DB9 port. This solved the problem.

Perfect cable! Definitely will buy another one.

This item didn't work out. I tried it several times but it didn't work.

Works with my routers and PC. No issues.
