Description

The USB-COMi and USB-COMi-SI Industrial Single RS-422/485 Adapters are designed to make serial port expansion quick and simple. Connecting to a USB port on your computer or USB hub, the USB Serial Adapter instantly adds one industrial RS-422/485 multi-electrical interface serial communication port to your system. By taking advantage of the USB bus, the USB Serial Adapter makes it easier than ever to add one RS-422/485 port and serial devices to your system with easy plug and play and hot plug features. Adapting the new technology, the serial port expansion now takes the new bus with easy and convenient connectivity.

Plugging the USB-COMi or USB-COMi-SI USB to Industrial Single Serial Adapter to the USB port, the adapter is automatically detected and installed. There are no IRQ & COM port conflicts, since the port doesn’t require any additional IRQ, DMA, memory as resources on the system. The RS-422/485 port functions as native Windows COM port, and it is compatible with Windows serial communication applications. The adapter is designed with external switches to set RS-422 or RS-485 ports and different operation modes conveniently.

The USB Serial Adapter provides instant connectivity to RS-422/485 communication devices for factory automation equipment, multi-drop data collection devices, barcode readers, time clocks, scales, data entry terminals, ATMs and serial communication in harsh environment. The USB to Serial Adapter is suitable for remote access, retail and industrial application, data collection and other applications requiring high speed RS-422/485 communication ports.
