Dart RTLS Hub
The Dart RTLS Hub houses a single board CPU that:
 Interprets the data sent from the Receivers.
 Generates the identity and location of each DartTag within a designated area.
 The Hub LAN interface makes the results available to client computers for further
processing and display.
The following figure shows the front view of the Dart RTLS Hub.
The Hub accepts input power of 100-240 Volts AC and provides power to the Receivers over a
CAT 5E cable. The same CAT 5E cable sends a clock source and serial communication data to the
Receivers. The front panel of the Hub has eight RJ45 connectors that are used for connecting
Receivers to the Hub. The Hub is capable of localizing Dart Tags with up to 64 Receivers per
Hub. Zebra recommends that you distribute the receivers among the ports to balance the
communication load.
Use care to only connect Receivers to the Hub port connectors on the front panel and to only connect LAN
cables to the Ethernet port connector on the rear panel. Improper connections may result in damage to Receivers,
Hub or external LAN equipment.
The following figure shows a rear view of the Dart RTLS Hub.
The Hub chassis is enclosed in a metal case with optional rack mount brackets. The rear panel of
the Hub has an Ethernet interface ETH0 (accessible through an IP network) for configuring the
Hub and passing output information over the LAN. ETH1 is disabled and should not be used.
