The Best Serial Adapters
Serial adapters allow serial connections to USB, Bluetooth, RS232, RS485 and other types of interfaces. Serial adapters can connect to one or more different serial protocols.
Our USB to Serial adapters have an integrated processing chip, either from FTDI or Prolific. Both chips work with Windows, Mac or Linux systems. FTDI is preferable to the Prolific chip because it is a more robust and system-friendly controller for 32-bit and 64-bit operating systems. Prolific works but can sometimes have installation issues. The USB equipment has the latest FTDI drivers available for download from their website. Some USB to serial adapters come with ESD protection or have circuit isolation to protect your device from sudden power surges.
