4-Port USB to Serial Adapter COM Retention FTDI Chipset 920K Baud Rate

Product Review (submitted on August 5, 2012):

This USB to serial port adapter has 4 separate serial cables that connect to a single USB 2.0 plug.

Each of the 4 serial cable ends is slightly more than 3 feet long. The USB cable end is one foot long. Total end-to-end length is a little bit more than 4 feet long.

Each serial cable is labeled "1", "2", "3", or "4" which makes it easy to track your connections. The connections always retain the same com port, so you won't need to reconfigure you software after restarting you computer.

The adapter has 3 separate LEDs: red = power, green = TX, yellow = RX.

The adapter comes with a CD-ROM that contains USB 1.1 and USB 2.0 drivers for many operating systems including Linux, Mac, Windows, and more. The release notes on the CD-ROM mention that newer drivers can be found at [...]

No paper instruction manual is included which might cause inexperienced computer users to have moderate difficulty with the setup. Experienced users will find the setup straight forward and simple.

Installation on Windows 7 was easy for me. I found the appropriate installer on the CD-ROM. I had to right-click the installer and select run-as-administrator. The first time I plugged the adapter in it took several minutes for the device to be detected, so be patient. Subsequent detections are fast.

All 4 serial adapters can be used simultaneously.

Overall I am satisfied with the quality of this device.
