Programming Timed Anti-Passback

When you enable Timed Anti-Passback, which is the default value, you must specify a length of time that must pass before the same
prox card can be processed after it's presented. This requires that the card be outside of the prox read field during the entire period of
time. If the card is reintroduced into the field prior to expiration of the time delay, the time delay restarts with a full duration.
Presenting a different card (not necessarily a programmed card) causes the new card data to be processed immediately and also clears
the Anti-Passback timer so that the first card presented now get processed again immediately.
Disabling the Timed Anti-Passback function provides another feature that controls how often ANY prox card is processed. When
option is disabled, the timer indicates how often a card will be processed. Please note that the prox read function continues to attempt
a card READ every 100 milliseconds, but a valid card read is only PROCESSED after the specified time delay elapses.
This function does not require the card to leave the read field. The main use of this feature is to adjust the processing rate of cards that
remain in the field. Now you can extend the processing time to stop this type of unwanted toggling. Simply extend the timer value to
accomplish this.
The anti-passback timer is set through command 32, parameter 3 (see below). The duration of the time delay can be set from a ½
second to 60 seconds in ¼ second increments.
The anti-passback feature applies only to prox cards; there is no "Anti-Passback" processing of keypad PINs. "Anti-Passback" and the
"card process timer" are also turned off in program mode.
