USB 2.0 RS-232 Serial Adapter

With LED Indicators

This USB 2.0 RS-232 Serial Adapter is the easiest way to add a serial port to your computer.

When connection activity is present, the LED’s will flash letting you know you have signal on the pins.

  • USB bus powered
  • 5ft. Cable connection

5 Stars
Works perfectly.
Excellent USB to Serial programming cable. Plug and play with Windows 10.Stay away from Prolific chipsets and pick an FTDI based cable like this one.Since this does not have the typical male screws to secure it to a DB9 female port (it has two female screw mounts / standoffs), I did have to forcibly remove the screw mounts / standoffs to actually use it with the device I needed to program (see pic).The indicator LEDs are a nice addition as well.
