Introduction:

This USB Industrial I/O Adapter is designed to make industrial communication port expansion quick and simple. Connecting to a USB port on your computer or USB hub, this USB Industrial I/O Adapter instantly adds and industrial multi-electrical interface serial communication port to your system By taking advantage of the USB bus, this USB Serial Adapter makes it easier than ever to add 8 serial ports and serial devices to your system with easy plug-and-play and hot plug features.

Plugging the USB Industrial I/O Adapter into the USB port, the adapter is automatically detected and installed. There is no IRQ & COM port conflicts, since the port doesn't require any additional IRQ, DMA or memory on the system. The RS-232, or RS-422/485, port functions as a native Windows COM port, and it is compatible with Windows serial communication applications. Each port is individually configurable on the outside of the USB-8COMi-RM box.

This USB to Industrial I/O Adapter provides instant connectivity to RS-232/422/485 communication devices for factory automation, multi-drop data collection devices, barcode readers, time clocks, scales, data entry terminals, PC to PC long distance communications, ATMs and serial communications in harsh enviornments. This USB to Serial Adapter is suitable for remote access, retail and industrial applications, data collection and other applications requiring high speed RS-232 or RS-422/485 communication ports.

Specifications & Features:
