Notes:
1.
The three tracks of data must be entered in order; for example, enter Track 1 first,
followed by track 2, then track 3.
2.
The maximum length of the data message of each track and the SS of each track are as
follows:
Track 1: 76 characters; Start Sentinel is % (25 Hex).
Track 2: 37 characters; Start Sentinel is ; (3B Hex).
Track 3: 104 characters; Start Sentinel is + (2B Hex).
3.
The optional Block Check Character (BCC) is appended to the message. It is generated
by exclusive ORing (XOR) each transmitted character including ETX, but excluding
STX.
4.
The End Sentinel character (ES) is 3F Hex (?) for all tracks.
5.
If a card is not swiped within the 30-second timeout, the unit will terminate the encode
operation and send a "T" response:
<STX>T<ETX>{BCC}
