helpful when assessing why location data is different than expected. It can be useful

in identifying undesirable reflected signals that may be causing Receivers to

contribute to location computations.

Dart Output Stream

With RTLS data information, the Dart data output stream has the location data

message in following format:

<Data Header>,<tag ID>,<X>,<Y>,<Z>,<battery>,<timestamp>,

 Detect Details. Select to include detect details in the locate. With this enabled, locates

will now contain details about RTLS receivers that detected the blink (Proximity

receivers are excluded from consideration here) and receivers that were pruned/pre-

pruned.

With additional detect details, the data output has the format Hrr[Pvv][Rvv] where

 Hrr : indicates receiver with receiver number rr detected the tag blink

 Pxx : indicates receiver rr was pre-pruned during tag location calculation in

virtual group xx. Pxx may not appear if the receiver was not pre-pruned in

any virtual group; it might appear multiple times if the receiver was pre-

pruned in more than one virtual group.

 Ryy: indicates receiver rr was pruned during tag location calculation in

virtual group yy. Ryy may not appear if pruning is turned off or if receiver

was not pruned in any virtual group; it might appear multiple times if the

receiver was pruned in more than one virtual group.

 Non Locate Data:

 Non-locate Details. Select to display detail information for events where location

data is not available. This is helpful when assessing why location data is unavailable

for a particular tag event.

For a description of the Non-locate details the Dart RTLS system generates, see Non-

locate Details (on page 85).

Dart Output Stream

With P-data information, the Dart data output stream has the presence data message

in following format:

P,<tag ID>,<X>,<Y>,<Z>,<battery>,<timestamp>,<receiver #>,<Non-

locate-Details><LF>

 N (Extended Non-locate) packets. Enable to get ‘N’ packets that contain extended

information for a ‘P’ packet. ‘N’ packets facilitate getting more information for a ‘P’

packet by including the detect details. The format of the ‘N’ packet is as follows:

N,<tag #>,0.0,0.0,0.0,<battery>,<timestamp>,00,<non-locate

details>,<detect details><LF>
