UOTEK 1.5M USB to RS-232 RS-485 RS-422 Converter USB2.0 RS232 RS485 RS422 Cable Serial DB9 Connector UT-8890
With the continuous development of PC industry, USB interface is gradually replacing various low-speed peripheral interfaces of old PC,however, many important devices in industrial environment still use RS-232/485/422 interface design, so many users use USB to RS-232/485/422 converter to achieve PC and RS232/485/422 devices data transfer between PC and RS-232/485/422 devices.
The UT-8890 is a universal USB/RS-232/485/422 converter with no external power supply, zero latency automatic transceiver conversion, unique I/O circuitry to automatically control the direction of data flow, and plug-and-play operation. It is suitable for all existing communication software and interface hardware.
UT-8890 interface converter can be point to point, data communication rate 300-921600bps, with power indicator and data flow indicator can indicate the failure situation, support the communication mode of USB to RS-232/485/422 conversion.
