Command: <STX><S><1Dh><01h><Decoding Method Settings><ETX><CheckSum>
Decoding Method Settings:
"0": Raw Data Decoding in Both Directions, sent out in ID TECH mode.
•
"1": Decoding in Both Directions. If the encryption feature is enabled, the key management
•
method used is DUKPT.
"2": Moving stripe along head in direction of encoding. If the encryption feature is enabled, the
•
key management method used is DUKPT.
"3": Moving stripe along head against direction of encoding. If the encryption feature is
•
enabled, the key management method used is DUKPT.
"4": Raw Data Decoding in Both Directions, send out in other mode. If the encryption feature
•
is enabled, the key management method used is fixed key.
With the bi-directional method, the user can swipe the card in either direction and still read the data
encoded on the magnetic stripe. Otherwise, the card can only be swiped in one specified direction to
read the card. Raw Decoding just sends the card's magnetic data in groups of 4 bits per character.
The head reads from the first byte of each track, starting from the most significant bit. The data start
to be collected when the first 1 bit is detected. No checking is done except to verify that the track has,
or does not have, magnetic data.
