INTERWORLD Electronics has announced a new line of embedded USB serial adapters, designed to seamlessly connect multiple serial peripherals via a single USB port.
This new product line enables manufacturers and integrators to easily incorporate multiple serial interface devices such as keypads, displays, card readers, and printers into custom enclosures that lack native serial port support without changing software written for serial port communications.
The QSU-100-EMB provides four independent RS232 serial ports that function exactly like a computer's native COM ports. The QSU-200/300-EMB is an equivalent adapter for RS-422/485 peripherals. The ESU-100-EMB and ESU-200/300-EMB provide 8 ports for RS-232 or RS-422/485 devices, respectively.
All are USB port-powered, provide data rates up to 230.4kpbs, and are compatible with Windows 98, Me, NT, 2000, XP and Linux.
The small-footprint boards have built-in surge suppression on the serial ports, necessary for maximum reliability and robustness. Mounting holes allow easy installation into cabinets and kiosks. Also included is a USB cable that both transfers data and powers the boards from the USB bus.
Interworld also offers a complete line of fully-packaged USB Serial adapters in 1, 2, 4, 8 and 16-port configurations.
