Serial Adapter types

Serial Adapter

A serial adapter is a type of device used for data transfer by adding more serial ports for access to a device. It is used in connecting to old machines that have fewer ports. By connecting the serial adapter to the device, the user is guaranteed more ports for data transmission subject to the number of ports the adapter has. Although, the transfer speeds aren't fast, which necessitates the increase in ports for data transfer. The USB to serial adapter is the most common form of the adapter used for enabling more data transfer options. It is important to note that adapters could have a female or male DB9 port and as such, this should be factored into the kind of adapter that would be bought when purchasing one. Inside an adapter, there are two kinds of processing chips;

  • USB to serial adapter chip which converts all the USB data to serial data and all the serial data to USB data and,
  • A serial driver chip that acts as a form of a powerhouse to amplify the connection(s) to the serial port(s).
