Magstripe
Select Magstripe to configure the Magstripe message output format.
In case the card ID-numbers are already programmed in the Wiegand or Magstripe format, then the below settings will
not be used.
Magstripe output message format:
<0xB><prefix><id-number><suffix><0xF><LRC>
Add start, stop-sentinel and LRC
This should normally remain enabled. According to the Magstripe ISO7811/2 standard the messages should begin with
a start-sentinel (0xB) and finish with a stop-sentinel (0xF) and LRC checksum.
Add preamble and postamble clocks
If enabled the Magstripe output will generate 16 preamble clock cycles before the message and 16 postamble clock
cycles afterwards.
Prefix
Constant prefix value transmitted before the ID-number. Max. 16 digits.
ID-number
Select to output the ID-number complete, left aligned or right aligned.
When left or right aligned specify the ID-length and offset in bits.
Convert to decimal
Enable to convert the ID-number to a decimal value. Default enabled because hexadecimal characters should be
avoided within the ID-number. Hexadecimal characters are, according to the ISO7811/2 standard, reserved for
message control.
Suffix
Constant suffix value transmitted after the ID-number. Max. 16 digits.
