Gearmo Industrial 8-Port USB to Serial Adapter DB9 RS-232 with FTDI Chipset, RX/TX LED Indicators, DIN Rail, & Surface Mounting Brackets Windows 11, 10, 8, 7 Support USB-A Cable Included

Unit works as it should. Drivers have to be installed via Device Manager. Currently using only one port.

works in Linux but...unfortunately NO Windows XP drivers available as stated in the descriptionwhich is why I bought itVERY DISAPPOINTED!!!

Its metal, reliable and DIN mountable. Works with Linux perfectly.

The Gearmo 4-port USB to Serial RS-232 hub works exactly as advertised on Windows 10, with plug n' play functionality if you already have FTDI drivers installed. For those who don't, the product arrives with a mini CD that has the necessary drivers so you don't have to hunt them down on the internet.HOW I USE IT:I ordered this product to allow me to open up a console session with my Cisco switches and it performs well in this capacity - mission accomplished.WHAT'S INCLUDED:1. CD w/ drivers2. Instructions.3. USB cable for PC connection4. Mounting screws and brackets for both wall and DIN rail mounting options.5. 4 port Serial hub with 4 DB9 ports, each with RX/TX LED indicators, DC power input, as well as power input terminals that accept between 9 and 45 volts of external power, but I've been using it without any problems with the power supplied via my PC's USB port.PROS:1. Easy to use. Just plug it in and its immediately recognized.2. The port numbers follow a logical order when listed in device manager, so no guess work is necessary.3. No external power is needed in my experience.4. Indicator LEDS for each serial port show if serial data is being received and/or transmitted.5. Build quality is simple and robust, with the ports for both USB and DB9 providing solid connections without wiggle or ambiguity.6. Compact.7. Comes with the necessary cable and mounting hardware, which is always a nice bonus!CONS:None.BOTTOM LINE:If you're in need of giving your PC serial super powers (aka DB9 ports), the Gearmo serial hub delivers without any headaches, and even throws in some extras like mounting hardware and the necessary drivers. Good product, recommended.

It does not come with a power source but it works greatExcellent seller, quick shipping, as described, great deal, I recommend!. Thank you!.
