After trying (and failing) using a well-reviewed Keyspan converter that I've had for several years (with TI chip and Keyspan driver), I tried this Gearmo with the FTDI chip and have had excellent results on an Intel Mac Mini with MacOS 10.14.6 (Mojave) with the stock FTDI driver that comes with MacOS. My application is using a remote serial console communicating with the getty daemon that MacOS also includes. I use RTS/CTS hardware handshaking at 19,200 baud and up, and haven't experienced any issues. The FTDI chip and the Apple driver appear to respect all the termios serial flags and commands used by the appropriate gettytab file entry (I had to modify my gettytab entry for the settings I used -- that takes a little work, but once you understand all the flags it's not bad). Finally, I like having the LEDs for the various serial lines. The Gearmo is a nice little product at a great price. Review: 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. ## Features - [ Enhanced Compatibility ] : Easily add a reliable RS-232 serial port to any USB-A computer, even if it lacks a built-in COM port. - [ Real-Time Monitoring ] : LED indicators flash during data transfer, allowing you to monitor connection activity instantly and confirming that data is flowing smoothly. - [ FTDI Chipset Advantage ] : Built with an advanced FTDI chipset, this adapter offers robust performance and compatibility with a variety of RS-232 devices, including PDAs, serial cameras, and more. - [ USB-A Connection for Legacy Devices ] : Supports a USB-A connection, ensuring compatibility for many laptops, desktops, and other USB-A devices. - [ Durable Design with ESD Protection ] : Enjoy high data transfer rates up to 1000kbps with built-in 15kV ESD protection, keeping your devices safe from electrical interference. - [ Cross-Platform Support ] : Compatible with Windows 7, 8, 10, 11, and Mac OS 10.X, along with Linux, making it a versatile and essential tool for your serial connectivity needs. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01DT8NFF6 | | Best Sellers Rank | #49 in Serial Adapters #22,362 in Cables & Accessories | | Customer Reviews | 4.6 4.6 out of 5 stars (195) | | Date First Available | April 4, 2016 | | Department | Business | | Is Discontinued By Manufacturer | No | | Item Weight | 6.4 ounces | | Item model number | GM-FTDI2-A36 | | Manufacturer | Gearmo | ## Product Details - **Brand:** Gearmo - **Color:** Black - **Compatible Devices:** Laptops, Desktops, Mouse, Printers, Tablets, etc. - **Connector Type:** DB9 Male w/Hex Nuts, USB Type A Male - **Specific Uses For Product:** Connecting legacy serial devices to modern host systems ## Images ![Gearmo USB to RS-232 Serial Adapter w/LED Indicators, FTDI Chipset, Cross-Platform Compatible, 36in Cable - Image 1](https://m.media-amazon.com/images/I/61cLzry6AoL.jpg) ![Gearmo USB to RS-232 Serial Adapter w/LED Indicators, FTDI Chipset, Cross-Platform Compatible, 36in Cable - Image 2](https://m.media-amazon.com/images/I/71VXNoOOgyL.jpg) ![Gearmo USB to RS-232 Serial Adapter w/LED Indicators, FTDI Chipset, Cross-Platform Compatible, 36in Cable - Image 3](https://m.media-amazon.com/images/I/71d8OJa4ViL.jpg) ![Gearmo USB to RS-232 Serial Adapter w/LED Indicators, FTDI Chipset, Cross-Platform Compatible, 36in Cable - Image 4](https://m.media-amazon.com/images/I/81-4bFnitfL.jpg) ![Gearmo USB to RS-232 Serial Adapter w/LED Indicators, FTDI Chipset, Cross-Platform Compatible, 36in Cable - Image 5](https://m.media-amazon.com/images/I/91rjubzbwKL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very well functioning USB-Serial Converter *by A***R on June 3, 2023* This is a very well functioning USB-RS232 serial converter.
