    Product Highlights

  • Enhanced Ethernet switch expands distance between synchronous Ethernet units over 100 meters apart
  • Use with DI-720, DI-730, DI-785, and DI-788 Ethernet products
  • 12 VDC power adapter included.
Description

The DI-789 is an Ethernet switch specially designed to work with DATAQ Instruments synchronized Ethernet products. Those products allow a number of data acquisition devices to be distributed with as much as 100 meters between units and still maintain high- or low-speed synchronous operation. The DI-789 repeater may be used when the distance between units exceeds 100 meters, or when ambient electrical noise renders long Ethernet runs unreliable.

The DI-789 is an enhanced Ethernet switch that is capable of managing the network to ensure that all data acquisition units in the chain remain synchronized. One or more DI-789s may be deployed with a maximum distance of 100 meters between other repeaters or data acquisition devices so that the maximum distance between a PC and one or more data acquisition units is virtually unlimited.

The DI-789 provides one each upstream and downstream RJ45 connector. Indicators consist of a power-on LED, and pair of LEDS that indicate upstream and downstream activity, and an LED that confirms network synchronization. The DI-789 is provided with an AC adaptor, and can also be powered from any 9-36VDC source.

Status LEDs
  • Bright red and green LEDs provide convenient activity notification when using the DI-789. The Power LED (green) indicates that Power has been applied to the DI-789. Ethernet activity LEDs (Toward PC and Expansion - both green) indicate activity over the Ethernet Data Lines. The Lost Sync LED (red) warns when the units are no longer acquiring data synchronously.

    Sync Management
  • Maintain synchronous data acquisition over distances greater than 100 meters with the DI-789. The DI-789 is an enhanced Ethernet switch that is capable of managing the network to ensure that all data acquisition units in the chain remain synchronized. Using a standard Ethernet switch will not allow the units to acquire data synchronously.

    Compatibility
  • Use the DI-789 with any combination of DATAQ Instruments DI-788, DI-785, DI-720, or DI-730 Synchronous Ethernet data acquisition units.

    9-36 VDC Power
  • All instruments are supplied with an adapter to operate from any convenient AC power outlet. Alternately, you can power the unit from any 9 to 36 VDC source.

    100 Meter Extension
  • Expand distances greater than 100 meters between Ethernet products while maintaining synchronous data acquisition using the DI-789 Repeater unit. One or more DI-789s may be deployed with a maximum distance of 100 meters between other repeaters or data acquisition devices so that the maximum distance between a PC and one or more data acquisition units is virtually unlimited.

    Easy Set Up
  • Simply plug in power and connect the Ethernet cables to your daisy-chained Ethernet data acquisition units. Use the provided TCP/IP manager software to quickly set IP addresses and ensure your unit is properly configured in your network.
