 The USB-4COMi-SI-M USB-to-Optical isolated Quad RS-422/485 Serial Adapter is
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 four 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 don't require any additional IRQ, DMA, memory as resources on the
system. The adapter is self-powered, and one power supply adapter of 6V/2.1 Amp is included.
The adapter
is designed with a four external 4-pin dip switches to set RS-422 or RS-485 mode conveniently, without the
need to open the metal chassis. Each port can be independently set to RS-422 or to RS-485, depending on
your requirement in application.
The adapter is with DIN rail bracket for industrial environment. Termination and biasing option are
available for data transmission lines. Optical isolation and surge protection are available to
USB-COMi-SI-M. The serial line of RS-422/485 port is optically isolated with 2000 volt DC optical
isolation. The optical isolation protects your PC from spikes and surges on the RS-422/485 network,
by converting the electrical pulse into an optical signal and then changing it back into an electrical
pulse.
The surges and spikes cannot cross the optical link. The adapter is built-in surge protector to
withstand electrostatic discharge and power surges up to 25KV ESD. The USB-to-Optical isolated
Quad RS-422/485 Adapter provides instant connectivity to RS-422 or 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 data communication in harsh
environments. The USB-4COMi-SI-M USB to Industrial I/O provides industrial solution requiring single node
or multi-drop communications over short and long distance.
Linux 2.4.0 and later, OpenBSD 2.9 and later & FreeBSD 4.7 and later. Drivers for the Windows
