D2119 Dart RTLS User Guide 99
visual notification of a large maintenance icon is shown at bottom-left corner of UWH-
1200 Dart Hub. This notification can only be cleared by rebooting UWH-1200 hub.
In case of auto recovery from system fault, care has been take in Dart RTLS firmware so that
reference timing established before system fault is preserved, and will be used after auto
recovery.
The port is color coded either grey or blue representing the port speed. When blue, it
indicates that all the receivers on that port support faster communication speed and so the
port is in 4M bit/sec. The default speed is 2M bit/sec and the port operating at the default
rate is colored grey.
Dart Hub monitors the CPU temperature by periodically reading it. If the CPU gets over-
heated (temperature above 85 C), then an over-heat icon is displayed on the bottom-left
corner of the UWH-1200 Dart Hub.
Detected Receivers are color-coded to indicate the Receiver status. The color code used is
listed in the Key box at bottom of the window:
 Green: The Receiver, like Receiver #01 on hub port 3, is fully operational; no warnings
exist.
 Light Green: The Receiver, such as Receiver #A1 on hub port 8, is fully operational;
receiver firmware upgrade is available.
 Yellow: The Receiver is operational, but warnings persist. For example, Receiver 81
connecting to hub port 5 is in yellow because it is not enabled for RTLS operation.
 Red: The Receiver is currently not operational; alarms persist. For example, Receiver
00000D39 is in red since it is not configured.
Each Receiver icon includes the number assigned to the Receiver and the Antenna type,
which can be any of the following:
 HG: High gain antenna
 MG: Mid gain antenna
 Omni: Omni-directional antenna
 Ext: External antenna, typically due to use of a bulk head Receiver to connect the
Receiver to an external or remote UWB antenna.
 RR: Receiver Repeater. A Receiver Repeater does not have antenna installed and it is
used to extend the cable reach where cable lengths greater than 1000’ are needed.
Each Receiver icon contains additional information including:
 Temperature (in Celsius)
 Voltage level
 Receiver Read Range
 ID (the unique 4-byte serial number on the back plate of the receiver)
The status of receiver read range is coded as a special character and appended to the receiver
# in the receiver icon.
