User-Data Format
MF7XX will send out the data following the format as below, the user data length defined by the Data-Info. At
wiegand output format, the data output length is fixed (defined by Number Of Bits), so the user data would be
cut if longer than Number of Bits, or the user data would be appended with zero “0” if shorter than Number of
Bits.

Data Type (11b)
Data Length
Data Type is fixed with 11b which meets “any other data” type of “Card Holder information” as MAD standard.
And data length is including the data with ending zero “0”, so the number of data byte sent by MF7XX is equal
to data length with one less for RS232 output.
Example: Data Length is 16, MF7XX only send out 15 bytes for RS232 output.
