When the Reader reads a valid card, it does not poll again until the hold-off time
has elapsed. During the hold-off time the Reader maintains the state of the LED
indicator (if the LEDs are under internal control).
To work out the hex number you need to type into the Programmer, refer to the fol-
lowing table:

Leading parity bit (p):
0
The Reader does not calculate a leading parity bit.
8
The Reader calculates an even leading parity bit based on the first 13 bits of
the 26-bit Wiegand interface (interface number 12). This saves you from hav-
ing to program the leading parity bit into the cards. The trailing odd parity bit is
still calculated as normal.
