Model 4168 Quad USB 2.0 Extender, Multimode Fiber, 4-Port Hub

  • Extend the Distance of Four USB Devices over 500 Meters.  Ideal for Platform Scale Applications.

  • Reliably extend USB 1.0 or 2.0 signaling over Multimode fiber cable to remote USB devices

  • Plug-and-Play, ready to operate right out of the box.

The desktop unit, Model 4168 is a 4-Port Hub that works with Model 4167 Host to comprise a local HOST and Remote 4-Port integrated USB HUB that directly accepts 4 USB load cells.  Together, the host and remote units extend the range of USB load cells from less than 5 meters to 500 meters via a high-speed Fiber interface.  Factory options can extend the distance up to 10 kilometers.

The units convert USB 2.0 compliant data from a standard PC Host interface over fiber to remote integrated 4-port powered USB Hub that directly accepts 4 USB load cells.  Operation of the Quad USB Load Cell Extender/Isolator is plug-and-play and fully transparent to the USB Load Cell, requiring no other hardware and no PC software.

This instrumentation is ideal for PC data acquisition requiring high speed data acquisition with optical isolation from electromagnetic interference.  The Model 4167 and Model 4168 system can extend a combination of USB load cells and other USB based devices using its integrated USB hub.

Applications include: industrial control, weigh tables, isolated data acquisition, and remotely located USB sensors.  The 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 at up to 480 Mbps).

The units have been tested to operate from 0°C to 50°C (component ratings meet or exceed 0°C to 70°C).  ESD protection circuitry is built into all copper USB I/O interfaces.  Both units' power inputs are protected from transients and the 4-Port Hub (Model 4168, 4168-DIN) provides the USB standard of 500mA per port.  The units feature; Power, Fiber Link Active, Host Active (Model 4167, 4167-DIN) and Port Active (Model 4168, 4168-DIN) indicator LEDs.

Two configurations are available for each model

  1.  Model 4167 Host Desktop Unit, for applications requiring an enclosure.
  2.  Model 4167-DIN Host Unit for applications requiring mounting on a DIN rail.
  3. Model 4168 4-Port Hub Desktop Unit, for applications requiring an enclosure.
