[. . . ] High Speed USB Serial Adapters - Embedded Models Board-level solutions with standard serial ports via USB 2. 0 Embedded High Speed USB 2. 0 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 Embedded High Speed USB 2. 0 Serial Adapters. [. . . ] It adds the COM port(s) via its USB connection and is compatible with new and legacy RS-232 or RS-232/422/485 devices. USB Embedded Serial Adapters are the ideal solution for a variety of industries and applications including banking, retail and industrial automation where PCs have a significantly shorter lifecycle than the peripherals that use them. Building on the success of the previous versions, the new generation of Quatech USB Serial Adapters hit speeds of up to 921. 6 kbps, 1024-byte FIFO and hardware and software flow control. Quatech Embedded USB Serial Adapters enumerate themselves as standard COM ports that are compatible with all standard RS-232 or RS-232/422/485 devices and software created for them. With the industrial surge suppression standard, you can safeguard the USB Serial Adapter when 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 (MEI or Multi-Electrical Interface).
