44N Set Uniqueness Timeout
See
“440 Reset Uniqueness” on page 7–95
Places a time limit on the uniqueness criterion set. Refer to
“410N Select Unique ID Code Criteria (Anti-
passback Feature)” on page 7–81
. The parameter N sets the number of minutes on the timeout clock.
The factory setting is two minutes (N = 1).
Command
Timeout Clock
#441
2 minutes (factory setting
)
#442
15 seconds
#443
30 seconds
Entering these commands effectively expires the timeout clock, which erases all current IDs in the
comparison register. In effect, the first ID that is acquired after the clock expires always appears to be new
and is stored. Newly acquired IDs are only tested against IDs that are registered after the clock resets.
The timeout clock is held in reset as long as the reader receives the same tag ID. For example, if the
timeout is set for 2 minutes (factory default), and a tag is sitting in front of the reader, the reader will not
report the same tag ID every 2 minutes. Otherwise, the reader will report the same Tag ID every 2 minutes.
450 Disable Wiegand Mode (Factory Default)
Command
#450
is a default set in the factory to disable Wiegand mode. To display status, use Command
“532 Display Wiegand Mode Status” on page 7–110.
Reader response:
Done
451 Enable Wiegand Mode
Command
#451
enables Wiegand mode, which allows the reader to transmit data in a format that
emulates the output of a magnetic card reader. To display status, use Command
Enabling Wiegand inhibits the output relay function. Refer to
“621 Select Predefined Output Control
(Factory Default)” on page 7–116.
Command
#621
is inhibited with Wiegand enabled.
In Wiegand mode, the reader transmits Wiegand-formatted tag data through the Wiegand interface and
ASCII data.
Note:
The reader will still accept reader commands and responds with tag data through the serial
port interface. The reader outputs data from Wiegand-programmed tags via the Wiegand interface
(the red/blue pair for data1/data0 and the black of the yellow/black pair for signal ground). Tags
that are not Wiegand-formatted are not transmitted through the Wiegand interface nor the serial
port when in Wiegand mode, although the tag lock relay is activated on any tag acquired.
