    USB-COMi-SI-M USB to RS-422/485 Adapter

    (with Optical Isolation & Surge Protection)

    The USB-COMi-SI-M USB-to-Optical isolated 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 a RS-422, or RS-485

    serial communication port 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 port dont

    require any additional IRQ, DMA, memory as resources on the system. The adapter

    is powered by the USB port, and no external power adapter is required.

    The adapter is designed with an external 4-pin dip switch to set RS-422 or RS-485

    mode conveniently, without the need to open the metal chassis. Both a 6-pin

    terminal block and a DB9 male connector are available for optimal flexibility for

    serial connection. The adapter also provides a unique feature of supplying power

    output of 5V/150mA through pin-5 of the terminal block to serial device. 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-RS-422/485 Adapter provides instant connectivity to 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-COMi-SI-M USB to Industrial I/O provides industrial solution

    requiring single node or multi-drop communications over short and long distance.

    Complete drivers support Windows Vista, XP, 2003, 2000, ME and 9x.
