enough information is available to calculate the position), or 1-, 2-, or 3-D calculations are
unsuccessful. You also use P-packets to show data from a Proximity Receiver.
 N: Extended Non-locate packet (N-Packet). N packets give extended information for a
non-locate ‘P’ packet. N packets contain the detect details and when enabled, are sent
instead of the non-locate P packets.
 D: Diagnostic packet (D-packet). D packets are optional error and/or warning messages
that are useful both during initial installation and for continuous monitoring of Dart
RTLS. For a complete description of D-packets, see D-packets (on page 107).
 <tag#> is the tag ID.
 <X>, <Y>, <Z>, except for "P" type data, are the calculated tag coordinates in feet or meters
with respect to a user-supplied origin, for R, T, and O type of data. In the case of P type of
data, <X>, <Y>, <Z> represents the coordinates of the Receiver that detect this tag message
transmission.
 <battery> is the tag’s battery indicator. The value is a number between 0 and 15, where 15
represents a fully charged battery. The battery value is not linear, nor is the curve the same
across all kinds of tags. The following table should be used to identify battery low condition
on a particular tag.
