There are a lot of devices out there that still communicate over RS232 but we bet your new laptop isn't one of them. Don't worry, though, we've got you covered. This 6ft converter plugs into your computer's USB port and provides you with a DB-9 RSR232 connection. After installing the drivers onto your Windows, Mac or RedHat Linux system, the FTDI chipset inside the cable will enumerate as a COM port with a baud rate adjustable to whatever setup you want to connect to.
We were curious what made this cable work, so we tore one open and found that it's simply an FTDI FT232 paired with a Zywyn ZT213 RS232 Transceiver. You can find the datasheets for those devices below as well as a link to the FTDI driver page. We've also uploaded a copy of the included drivers CD in zip format.

Worked great right off. No problems.
Nicely replaces a unit whose driver support ended with OS/X Yosemite and Windows 7.
This converter uses the FTDI chipset on the COMM port side which has been recommended by serial equipment manufacturers. The Zywyn ZT213 RS232 transceiver on the other end is likewise recommended. The software package does not include Windows 10, however the Windows 8 software does work with my Windows 10 laptop.
Using it to control my Ham radio (Ten-Tec Omni VI Plus) with my PC. Using the program WSJT-X. working fine :-)
Still waiting for the inspection report so unable to comments on the performance and working. But the Packing and Delivery was Superb and 5 star rating.
This cord is the second that I have purchased to take with me as I travel working on CNC machines. I have always been able to communicate with the old boards that I have needed to (almost always Fagor controllers or drives). It is a nice size and length to travel with and gets the job done.
I have only used it in the three wire mode (gnd, Tx, and Rx) and it works well in that mode. I would buy another one.
