DI-789 RepeaterEnhanced Ethernet Switch Expands Distance Between Synchronous Units over 100 meters apart
Product Highlights Product Highlights
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 LEDsBright 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 ManagementMaintain 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. CompatibilityUse 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 PowerAll 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 ExtensionExpand 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 UpSimply 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. Ordering Information, Models, and Prices
