Description
This USB serial device is a USB 2.0 to RS-232 serial adapter used to easily add a serial port to your computer even if they are unequipped with COM port ability. The GM-FTDI2-LED supports peripherals requiring a serial RS-232 connection. This USB serial adapter allows you to add a single serial port and monitor the status of your connections by using LED activity flashes.
When connection activity is present, the LED’s will flash letting you know you have signal on the pins. The GM-FTDI2-LED offers an advanced an FTDI Chipset supported by Windows 11. The device is powered individually by the USB 2.0 port and is easy to install with Plug & Play and easily tests RS-232 Host to Device link with backward compatibility with USB Spec 1.1.

It works fine
Easy to setup and use.

This is the one to get
Don’t mess around with other chipsets that can be unstable, have poor driver support and even may cause Blue Screen of Death when connecting and disconnecting. This has the very reliable FTDI chipset with status indicator lights at a great price. Cheers! ~Andrew

great deal
I have needed this for a while now. I ordered and received easy to use and worked perfect. makes life easier programming 2-way radios.

Very helpful when resolving RS232-USB problems
Too bad they put on the sticker slightly shifted so the indicators were not clear to see. Re-sticking it is a bit of a pain. For the rest a very handy and good working device.

Okay. Usable – though not perfect
It didn’t work for my project but I suppose I can use this cable. I will keep it. I like the data light feature, that’s the best thing about it.In terms of quality— It’s too expensive for the cheap looking design and feel.

Worked great on multiple devices so far.
I have had no issues connecting to, Watchguard, Cisco, Dlink, HP switch with this adapter and the Serial to RJ cable.

Fast delivery
Works, but found I didn’t need it right away.
JC –
Compatibility
Works great with Windows 10
Virgil N. –
Not a problem
Plug it in and it worked
Wulfie –
Rock solid connectivity so far
The female connector screws refuse to come out, annoying since i cannot use the dongle directly on the equipment ,have to use a male female cable extension.

Works just fine, would buy again
It reports to the OS that it is FTDI, who knows anymore. But it works absolutely fine, would buy again.

Works perfectly, no additional drivers needed
Worked (almost*) right out of the box. Tested only in Windows 10 64 bit.Needed to program a universal remote (URC MX-800, also should work with all other variants like MX-600, MX-700, etc). *The default latency was set to 16ms which made it not communicate with my equipment properly, but setting it to 1ms in device manager solved it.LED’s are nice and useful, you can see which lanes/pins are actively receiving or transmitting.Material of the case is good.Two things that could make this even more perfect in my humble opinion.Make the cable the same color as the case (smoke colored). As it is, it looks like something from 2003 or so with its see-through cable and being able to see the sheilding.Second, if they could somehow add a opaque piece of plastic between each LED so the light doesnt bleed into the holes next to it, it would look so much more nice looking and easier to read the LEDs.
