output a P-packet, indicating that a tag is visible by that Receiver but position
information is not available. For more information on P-packets, see System Output (on
page 83).
 Read Range: Select a value to control the Receiver sensitivity. The value can be from 1 to
25 if in coarse range control mode, or from 1 to 54 if in fine range control mode. A
Receiver is most sensitive (has the longest read range) when the Read Range is set to 25
for coarse range mode (or 54 for fine range mode). To set a receiver to the minimum read
range, use a Read Range value of 1. For more information on read range settings and
how these map to actual read ranges, see Appendix: Receiver read range (on page 125).
Read Range cannot be specified for a remote receiver.
 Remote Rx#(hex): Enter the receiver number of the remote receiver. This should be the
receiver number of the receiver as configured on the remote hub. If the Receiver is local,
then Remote Rx # is 0.
 Remote Hub: Enter the IP address of the remote hub on which the remote receiver exists.
If the Receiver is local. Then Remote Hub is 0.0.0.0
To delete a Sensor, right-click the respective row and select Remove.
4 Repeat Step 4 for all Receivers connected to this Hub.
5 Click Save for the Sensor settings to take effect.
Configuring reference tags
To compute x-y or x-y-z position, Dart RTLS requires the use of one or more reference tags.
These tags help establish a common time base among the Receivers.
For a reference tag to be useful, it must be in a location that is unobstructed from at least two
Receivers and not be moved from its configured position. Receivers should have an
unobstructed path. If required, you can use many reference tags. However, it is generally better
to use as few reference tags as possible. When deciding on how many reference tags to
configure, keep these rules in mind:
 Associate each receiver with at least one reference tag.
 Associate each reference tag with more than one receiver.
The Dart Hub software uses reference tags to establish timing for computing RTLS location data.
Reference tags are critical to establishing timing whenever a system restart occurs. Each of the
following conditions causes a system restart:
 Any change to the setup of RTLS receivers and reference tags
 Perform a diagnostic test (Receiver Test , System Test or Cable Test)
 Clicking the Restart Firmware, Reboot Hub, or Shutdown Hub buttons
 Any power cycle to the Dart Hub
 Enabling reference tag suspension
