A Serial Adapter also referred to as a serial converter or RS232 adapter is a small device that converts serial data signals into various other formats that are more widely accepted in modern technology. Serial signals are often found in modern industrial devices and older personal hardware such as PCs, printers, and scanners. The most common serial adapters are RS232 to USB Adapters which Coolgear makes many variations of. This sort of adapter comes in USB-A, USB-B, and USB-C, from 1 port to many ports. If you need to utilize your serial devices on machines that don't have serial ports, we have the serial adapter for you.
