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

It works as expected, a cheaper generic device burned up my pi so I had to replace it and got this for the rs232 connection. Considering the cost of a new pi this is a good value.

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.

Works great with my windows 7 and my Gerber GS750 plus plotter and Gerber omega software! Will say the instructions stink on the disc, but I didnt need them thankfully

After having struggled with corrupt data on my PL2303-based adapter every few minutes, I was suspecting problems with the target device, especially when the problem persisted after swapping adapters, reloading drivers, and trying a different PC.Lesson learned: Replacing a Prolific chip with another Prolific chip isn't gonna fix it! Go FTDI or go home.I bought (two of) these and the problems haven't come back; I can receive *megs* of text without so much as a hiccup. Logging over a long weekend used to be completely out of the question, now it's become routine.And yes, the diagnostic LEDs are every bit as useful as you'd imagine, perhaps more so. Not only do they show you TX/RX and flow control, but they show you *when the port is open at all*, which is super handy if you've got multiple adapters plugged in and you've lost track of which COM port is which. Forget the paperclip loopback! Forget unplugging things to see which port stops responding! Just watch each adapter go all Christmas-tree when you open its respective port, and the mystery is conclusively solved.My colleague has been using the other one to drive an old board plotter, which had exhibited inexplicable, random, and extremely frustrating bugs for months. Switching to a genuine FTDI adapter made everything suddenly work! The misbehavior is gone, the software doesn't lock up anymore, and we're back to making boards in-house instead of sending them out. Turns out the plotter wasn't bad after all, it was just a cheap serial adapter!I'm never skimping on cheap serial adapters again.

Worth every penny.It doesn't need special drivers to work.easy to connect and good quality

Excellent adapter and easy to configure. I would recommend this product.
