About USB to Serial Adapters

A USB to serial adapter is a general term for what can actually be a USB to RS232 adapter, a USB to RS485 adapter or a USB to RS422 adapter. When you are dealing with this type of adapter you will need to specify which protocol you are actually referring to.
These three types of serial adapters usually look almost the same so you will have to look carefully on the specification label of the adapter to determine which type of adapter you have.

These types of adapters are available as simple non-isolated tabletop adapters which are ideal for hobbyists and other consumer applications; however they are also available as fully optically isolated converters with rugged housing and DIN mount for heavy duty industrial use.
All types are also available as 1-port models or multi-port models with up to 64 serial COM ports or more; however the most commonly used number of ports are 1 to 4 port adapters.

Selecting an adapter with a good quality processor and circuitry is important if you want to avoid communication or driver problems. We highly recommend a USB to serial adapter with a FTDI or Silicon Labs processor since these are some of the most reliable and industry proven processors on the market.
