[. . . ] High Speed USB Serial Adapters
Standard serial ports via USB 2. 0 without replacing peripheral hardware or application software
For over 20 years, Quatech has been known to help you Connect with Reliability. [. . . ] The "IND" option is ideal for implementing USB-to-serial networks in factories, power plants and other potentially harsh industrial environments. The 400 Series models introduce the software-selectable RS-232/422/485 (Multi-Electrical Interface or MEI). LEDs visually tell you which ports are using which protocol, so go ahead, mix and match. Auto detect between RS-422 and RS485 with Quatech's new USB Serial Converter. Embedded USB Serial Adapters for custom enclosures If you're looking to seamlessly connect multiple serial peripherals via a single USB port in a custom enclosure, try Quatech's board-level solutions, Embedded USB Serial Adapters.
