pulses from the DartTags and generates packets of information, which are in turn sent to the
Hub over a CAT5E cable.
You can connect the Receivers directly to a Hub port connection or in a daisy chain to other
Receivers. Each Receiver receives 48VDC from the previous Receiver (or from the Hub if it is the
first Receiver in the line) and passes the 48VDC on to the next Receiver in line via the CAT 5E
cable.
Similarly, each Receiver receives a clock and bi-directional data from the previous Receiver (or
from the Hub if it is the first Receiver in the line) and passes these on to the next Receiver in line.
The following figure shows Dart RTLS Receivers.
The back of each Receiver includes two RJ45 connectors, as shown in the following figure, one to
connect to the previous Receiver or Hub in the line (labeled IN) and one to connect to the next
receiver in line (labeled OUT). When the Receiver is getting power, a yellow LED flashes on
when data is being read from the Receiver.
The flashing may be too short to be noticed when data traffic is high.
Each Receiver requires approximately 35ma at 48VDC, which is supplied by the previous
Receiver in the line (labeled IN) or the Hub.
Each Receiver has:
 An auxiliary DC connection that supplies additional power to the Receiver when Hub power
is not adequate (not typically used).
Use of Zebra external power supply is limited to indoor use and a max 40°C environment. External power supplies
should power a maximum of 6 Receivers per power supply. Only use Zebra approved power supplies.
