(2) Model 4112-DIN Host Unit for applications requiring mounting on a DIN rail.
(3) Model 4119 4-Port USB Hub Desktop Unit, for applications requiring an enclosure.
(4) Model 4119-DIN 4-Port USB Hub Unit for applications requiring mounting on a DIN rail. 

 Model 4112/4119 Host and 4-Port USB Hub Typical Application, ST Duplex to USB Converter/Extender

FEATURES: 

  • Convert USB 2.0 compliant data from a standard PC Host interface, Model 4112, over fiber to a remote 4-Port powered USB Hub, Model 4119.
  • Ideal for applications involving PC communication that require high speed, secure communication, and optical isolation.
  • Extend USB communication in environments that are subject to high EM or RF interference that might corrupt communication over a copper interface.
  • Typical applications include industrial control, KVM extension, remote desktop USB connections, and remote USB device sharing such as printers, scanners and storage devices.
  • Units offer true plug and play operability with support for Windows®, Mac OS®, Linux®, and support all USB device types: Control, Interrupt, Bulk and Isochronous up to 480 Mbps. 
  • Designed to operate from -0 degree C to +50 degree C
    (component ratings meet or exceed 0° C to 70° C).
  • Units feature ESD protection circuitry on all copper USB I/O interfaces, per IEC 61000-4-2 standard.
  • Power inputs are protected from overvoltage, overcurrent, and high power transients.
  • The 4-port USB Hub provides the USB standard of 500mA per port.
  • LEDs display Power, Fiber Link Active, Host Active (Model 4112, 4112-DIN)
    and Port Active (Model 4119, 4119-DIN) indicator LEDs.
