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
denitions with custom site and user code positions for the
Wiegand string.
When searching the bit string for the user code, the digits are
identied and read from left to right.
