Wiegand Code Length
When using a custom credential, enter the total number of
bits to be received in Wiegand code including parity bits.
Press any select key to enter a number between 1-255 to
equal the number of bits. Default is
26 bits.
An access card contains data bits for a site code, user code,
and start/stop/parity bits. The starting position, location, and
code length must be determined and programmed into the
keypad. See Figure 7.
