USB to Serial Adapters

USB C to SerialUSB to serial adapters are an essential part of your laptop or notebook computer that does not have a serial COM port on board. USB to serial applications such as stenography, bar code scanners, and COM terminals are supported through signal interaction with the serial protocol and USB host connection. These are also called USB serial converters and they provide full RS-232 / 422 / 485 signals with LED diagnostics and activity indicators. Choose the USB to serial adapter for your needs from Gearmo!
