usb-rs232 serial db9 converter

Specifications

usb-rs232 serial db9 converter details:

HighTek HU-01 is a universal USB/RS-232 interface converter. No external powersupply needed. Compatible with USB and RS-232 standards, HU-01 iscapable to perform the conversion from single-ended USB signal into UARTsignal of RS-232. DB9 male connectors are used for connection from RS-232interface. The unique I/O circuit of the internal zero delay auto transceivercontained in the converter controls the data stream direction automatically.

The converter is plug-and-play. All these features ensure a universalapplication on all the existing communication software and hardware interfaces.

The data communication rate can be as high as 300-921.6Kbps by the point-to-pointcommunication by HU-01 interface. Power indicator light and datatraffic indicator light are also available with the converter for malfunctionindication. Conversion fromUSB to RS-232 is supported.
