The tab displays the UWH-1200 hub and Receiver daisy chains connected to each hub port.
Receivers are drawn in different rectangular box shapes, depending on their capability:
 A rectangular icon, , represents a Receiver that does not support firmware upgrade;
 A rectangular icon with the bottom-right corner missing, , represents a receiver
compatible with firmware upgrades;
 A rectangular icon with the bottom-right and upper-left corner missing, , represents
a receiver compatible with ISO/IEEE formatted tags.
The Dart Hub real time detects the receiver connections and displays visually in the right
order on each port. Dart hub also measures the length of the cable between hub and receiver
and between adjacent receivers if the receiver firmware ( version 5.3.1 and above) and hub
FPGA firmware (version 1.1.2 and above) support cable length measurement. The cable
length is displayed section wise along with the units of measurement, rounded off to the
nearest ten. Dart hub also continuously collects receiver status and updates them on the
status page.
The connection order and cable length cannot be obtained for Remote Receivers and they are
displayed in random order, on the port labelled ‘Remote’.
When a potential cable defect, such as loss of input clock at a receiver, is detected on a daisy chain, the
maintenance icon is painted on the corresponding port. In this case, a diagnostic Cable Test is
recommended for this hub port. This maintenance alert will be cleared on Dart RTLS firmware restart.
In the unlikely event that UWH-1200 has to auto reboot to recover from a system fault, a
