Item code: USB-COMi-M

Quality USB to RS232/RS422/RS485 serial adapter with the FTDI chipset for best compatibility.

Introduction:

The USB Industrial I/O Adapter is designed to make industrial communication port expeansion 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 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.

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 Industrial I/O Adapter provides an industrial solution for applications requiring a single node or multi-drop communications over short and long distances.
