USB to Industrial RS-232/422/485 Adapter
Introduction of USBG-COMi-M
The USB to Industrial RS-232/422/485 Adapter is designed to make industrial
communication port expansion quick and simple. Connecting to a USB port on your
computer or USB hub, the USB Industrial RS-232/422/485 Adapter instantly adds an
industrial multi-electrical interface serial communication port to your system. By
taking advantage of the USB bus, the USB Industrial I/O Adapter makes it easier than
ever to add RS-232, RS-422 or RS-485 serial device 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 to Industrial RS-232/422/485 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-232, or RS-422/485, port functions as native Windows COM port, and
it is compatible with Windows serial communication applications. Each port is
individually configurable.
The USB to Industrial Serial Adapter provides instant connectivity to RS-232/422/485
communication devices for factory automation equipment, multi-drop data collection
devices, barcode readers, time clocks, scales, data entry terminals, PC to PC long
distance communications, ATMs and serial communication in harsh environment.
The USB to Industrial I/O Adapter provides industrial solution requiring single node
or multi-drop communications over short and long distance.
