Number of User Code Digits  (7863, 7873 only)
The keypad recognizes user codes from four to ten digits in 
length. Touch the display to enter the user code digit length 
being used by the panel.  Default is 5.   
For an XR100/XR500 Area System, use 4 to 10 digits (typically 
5). For all other systems and panels, use 4 digits.
Any selection above 5 digits requires entry of the custom card 
definitions with custom site and user code positions for the 
Wiegand string. 
When searching the bit string for the user code, the digits are 
identified and read from left to right.

Arming/Disarming Wait Time 
 
(7873 only)
Select the number of seconds (1-9) the keypad should wait 
when an area system displays  ALL?  NO  YES during arming/
disarming or a HOME/SLEEP/AWAY system waits during arming 
only.  If NO or YES, or HOME, SLEEP, or AWAY is not manually 
selected before the delay expires, the keypad automatically 
selects the YES or the AWAY key.  Enter zero (0) to disable 
this feature.  The delay also occurs when any credential is 
presented for arming the HOME/SLEEP/AWAY system.

Wiegand Code Length  (7863, 7873 only)
When using a custom credential, enter the total number of 
bits to be received in Wiegand code including parity bits.  
Touch the display to enter a number between 0-255 to equal 
the number of bits.  Default is 26 bits.
Typically, an access card contains data bits for a site code, 
a user code, and start/stop/parity bits.  The starting 
position location and code length must be determined and 
programmed into the keypad.
