NOTES
•
Proximity masking allows you to select specific portions of the decimalized proximity data to include in the saved data.
By using the masking, you can effectively "mask out" any unwanted portion of the data. You can also insert characters into
the data using this command.
•
There is one mask for each of the programmable proximity formats. The mask is executed only if the prox card matches the
length specified in the prox format,, and masking is explicitly turned on.
•
To select a specific part of the data to include in the saved data, set the p(x) parameter to the starting position in the data,
and set the ll(x) parameter to the length to select. You can also set the length to 000 which selects all of the data starting at
the position p(x).
Example:
To insert a character in the masked data, set the p(x) parameter to 00 and in the ll(x) parameter specify the character to insert,
using the 3-digit decimal value of the character/
Example:
Each mask requires 2 commands to be sent to the reader - part 1 and part 2.
