USB-2COMi-SI-M 2 Port RS-422/485 Optical Isolated Adapter User Manual
The USB-2COMi-SI-M 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, the USB
Industrial I/O Adapter instantly adds industrial 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-422 or RS-485 device
to your system with easy plug-and-play and hot plug features.
Adapting the new technology, the industrial I/O communication port
expansion now takes the new bus with easy and convenient
connectivity.
Plugging the USB Industrial I/O 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-422 / 485
port functions as native Windows COM port, and is compatible with Windows serial communication applications.
The USB Industrial I/O Adapter provides instant connectivity to RS-422/485 communication device for factory
automation equipment, multi-drop data collection devices, barcode readers, time clocks, scales, data entry terminals, PC
to PC long distance communications and serial communication in harsh environments. The USB Industrial I/O provides
industrial solution for applications requiring single node or multi-drop communications over short and long distance.
Optical Isolation and Surge Protection
Each RS-422/485 port is individually optically isolated with 2000 Volt DC optical isolation. The optical isolation protects
your PC or notebook 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. Your computer is well protected, since the surges and
spikes cannot cross the optical link. Each RS-422/485 port is individually protected by surge protector to withstand
electrostatic discharge and power surges up to 25KV ESD. Surge suppression on all signals prevent from damages caused
by lightning or high voltage.
