1 DartWand basics
Sapphire tags and DartTags are battery powered devices that periodically transmit their unique ID over
Ultra Wide Band (UWB) radio frequencies. Sapphire tags support a single transmission rate that is set at
the factory, whereas the rate of DartTags is user-configurable.
A typical UWD-3100 DartWand system consists of a computer with DartWand software, DartWand USB
cable, and an optional barcode scanner. The DartWand can configure the blink rate of DartTags. In
addition, the DartWand can display inventory of nearby Sapphire or DartTags that are transmitting UWB.
The UWD-3100 DartWand hardware contains low frequency (LF) coils for transmitting configuration
commands to DartTags. The range of this magnetic communication is 1 or 2 feet. The UWD-3100
DartWand also contains a UWB receiver that has a range from several inches up to 500 feet, depending on
the software range setting and on environmental factors.
The DartWand software consists of USB device drivers plus an application for configuring tags and
performing UWB inventories. An optional barcode scanner can be used to scan the barcode shipping label
on the individual tags, or the barcode label on a box of tags.
