• Bit 33: last parity bit, “odd” type. Its value is such, that the 17 last bits together (bit
33 included) contain an odd number of ones (‘1’).
Free format
A Card Reading event is issued, directly transferring all bits received through the
Wiegand port, with no format processing at all. For that reason, whatever parity bits that
might exist are also included in the Card Reading data.
No parity check is performed, so caution must be taken if the incoming data is to be used
for access control or other applications where security is required: data integrity is not
guaranteed in Free Format mode.
A.3.4. Configuration example
The simplest case consists of enabling a Wiegand-26 bit reader through TTL_1:
• Enable Wiegand-26 bit input on TTL_1 port: Parameter$0F to $21
• Enable TTL_1 for Card Reading, no prefix: Parameter$08 to $08
• Enable beeper if correct reading: Parameter$09 to $88
• Enable beeper if incorrect reading: Parameter$0A to $88
