4.2.4 Custom Configuration WherePort Retrigger
Selecting <D> WP Retrigger from the custom configuration screen 1 will allow
the user to set the WherePort retrigger timeout and mode. The same WherePort ID
will be ignored after causing tag blinks until the retrigger timeout expires. The
mode selects the event that starts the timer. In retrigger mode 1 (values with ‘L’
added to the time in seconds) the retrigger timer starts after the tag sends its last
WherePort blink from the previously received valid WherePort message. In
retrigger mode 2 (values with ‘E’ added to the time in seconds) the retrigger timer
will not start until the sends its last WherePort blink AND the tag has left the
WherePort field. If the same WherePort message is received before the timer
expires, the time is reloaded and the retrigger timeout starts over. In retrigger
mode 3 (values with ‘EF’ added to the time in seconds) the retrigger timer operates
the same as in mode 2, only when the timer does expire, the tag will send another
set of WherePort blinks – with the “LEFT WP FIELD” bit set. The retrigger times
can range from 1 second to 2 minutes. As soon as the user selects one of the
available timeouts, the WhereWand application will return to custom configuration
screen 1 to allow another parameter to be selected and modified. The user can
press <Enter> to move to between the WherePort retrigger pages, or <ESC> to
return to the previous menu. Anytime the tag enters the field of a different
WherePort, the blinks and retrigger from the previous WherePort are aborted and
the process begins for the new WherePort. Figure 14 shows the flow diagram of
the blinks and retrigger for one WherePort. Figure 15 shows the available
retrigger times. This configuration parameter applies only to tags with ID greater
than 17,000,000.
