Connecting to a USB port on your computer or USB hub, the USB Serial
Adapter instantly adds eight RS-232, or RS-422, or RS-485 serial communication ports to your system.
By taking advantage of the USB bus, the USB Serial Adapter makes it easier than ever to add serial ports
and serial devices to your system with easy plug-and-play and hot plug features. By plugging the USB
Serial Adapter to the USB port, the adapter is automatically detected and installed.
There are no IRQ &
COM port conflicts, since the ports dont require any additional IRQ, DMA, memory as resources on the
system. The adapter is self-powered, and has built-in switching power supply of 100V/240V (input) inside
the chassis. The adapter is designed with eight external 4-pin dip switches to set RS-232, RS-422 or
RS-485 mode conveniently, without the need to open the metal chassis. Each port can be independently
set to RS-232, RS-422, or RS-485, depending on your requirement in application. The adapter is with DIN
rail bracket for industrial environment.
The adapter can be also mounted to a 19" rack, and the rack mount kits are included with the adapter.
Termination and biasing option are available for data transmission lines. The USB-to-Octal RS-232/422/485
Adapter provides instant connectivity to RS-232, RS-422, RS-485 communication devices for POS, factory
automation equipment, multi-drop data collection devices, bar code readers, time clocks, scales, data
entry terminals, PC to PC long distance communications, ATMs and serial communication in harsh
environments. The USB-8COMi-RM USB to Industrial I/O provides industrial solution requiring single node
or multi-drop communications over short and long distance. Complete drivers support Windows XP, 2003,
2000, ME and 9x.
