Quatech has a new line of embedded USB serial adapters that are 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 support without changing software written for serial port communications.

"We developed this line in response to strong customer demand for a robust, cost-efficient way to integrate multiple serial peripherals into kiosks and other POS enclosures", said Steve Runkel, Quatech's President and CEO.

"The new products were designed around customer specifications and engineered to the exacting reliability and performance standards our customers expect from Quatech USB serial adapters".

The QSU-100-EMB ($129 MSRP) provides four independent RS232 serial ports that function exactly like a computer's native COM ports.

The QSU-200/300-EMB ($149) is an equivalent adapter for RS422/485 peripherals.

The ESU-100-EMB ($269) and ESU-200/300-EMB ($299) provide eight ports for RS232 or RS422/485 devices, respectively.

All are USB port-powered, provide datarates up to 230.4Kbit/s, 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.

Quatech also offers the industry's most complete line of fully-packaged USB serial adapters in one-, two-, four-, eight- and 16-port configurations.
