This USB to RS-232 converter with galvanic isolation worked well for interfacing older serial devices to our modern USB-based control system. The power from the USB port was sufficient, and its compact size fit easily inside the equipment enclosure. It met the IP20 protection level needed for our indoor installation without any issues. Installation was straightforward and reliable communication was maintained during testing.
