USB Singe-Port Serial Adapters Upgrade to USB connectivity without replacing peripheral hardware or application software. KEY FEATURES Single port configurations RS-232 or software-selectablen RS-232/422/485 Device enumerates itself as standard port Baud rate up to 921 kbps Full modem control and hardware and software flow control (RS-232) Full-duplex or half-duplex modes (RS-422/485) Connect serial peripherals with USB Single Port Serial Adapters Bus powered, no external power required Quatech USB Single Serial Port Adapters are easily configured to enable the 3000V DC optical isolation continued use of legacy devices without making any changes to the applications option (SSU2-400I) written for them. The adapters enumerate themselves as standard COM ports 15kV DC ESD Immunity making the USB interface completely transparent to software. (SSU2-300/400I) Surge and short cicuit protection Quatechs USB Single Port Serial Adapters are based on the idea that taking advantage of new technology should not necessitate abandoning legacy devices and Terminal block connectors on RS-422/485 units the applications written for them.
