User manual QUATECH USB 2.0 ADAPTERS DATASHEET

[. . . ] 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. KEY FEATURES 1, 2, 4 or 8 independent serial ports RS-232 or software-selectable RS-232/422/485 Compatible with USB 1. 1 Plug-and-play capability Devices enumerate themselves as standard COM ports Speeds up to 921. 6 kbps High speed UARTs with 1KB FIFOs to boost data rates Optional surge suppression package (standard on Embedded products) Full modem control and hardware and software flow control Bus powered: no external power required Embedded (board-only) units also available Windows 2000/XP/Vista and Linux RoHS compliant NEW!USB to RS-422/485 Converter 5 year warranty Connect serial peripherals with USB 2. 0 Serial Adapters If speed, expansion and support are what you're looking for in a USB Serial Adapter, think Quatech. You can now broaden the range of external peripherals used on your computer at higher speed rates than the USB 1. 1 series, with the introduction of the High Speed USB 2. 0 Serial Adapters. The USB 2. 0 has more bandwidth that allows higher data rates on the serial ports for more efficiency.
