Description & Features+

The ICUSB2321F 1-Port USB to Serial RS232 Adapter Cable with FTDI chipset and COM Retention converts an available USB 1.1 or 2.0 port into an RS232 serial DB9 port to connect, monitor and control your serial devices. This compact adapter features COM retention, allowing the same COM port value to automatically be re-assigned to the port if the cable is disconnected and re-connected to the host computer, or if the system is rebooted. The ICUSB2321F uses the FTDI chipset which supports additional customization, advanced features, and compatibility not necessarily offered by other solutions. Compatibility with a broad list of Operating Systems including Windows®, Windows CE, Mac OS and Linux, makes this product easy to integrate into mixed environments. Backed by a StarTech.com 2-year warranty and free lifetime technical support.

Rated 5 out of 5 by from •USB to Straight-Through RS232 Serial Adapter This does work great with Singer PSW. It is plug and play up to Windows 10. No need to install the software on disk, just plug in and it works great. I think it is even faster than my old cable I had before. East to use and I highly recommend.

Rated 4 out of 5 by from Works like a true serial port Works like a true serial port without an usage problems. There is 1 problem, if the device is unplugged from the PC before the PC is powered down, when the PC is powered down it will come up with windows blue screen. There is no problem if the PC is powered down and the device is removed after shutdown.

Rated 5 out of 5 by from A-OKAY Easy to Install and worked great. If just passing data from another serial device without a physical port (ie automobile Diagnostic plug ALDL) then port must be configured as loopback. Pins 1,4,6 shorted together at serial plug and pins 7,8 shorted with data on pin 2 and Ground on pin 5.
