Reading and Decoding
The ticket is taken from active position, and after reading, the ticket returns to active position.
Magnetic Encoding Attributes
7
The magnetic encoding data strings can be given attributes that govern versions of the standard
encode/read-after-write routines and cancellation functions.
The following attributes, inserted anywhere in the applicable data strings, will cause the
following functional deviations from default standards:
!D
Reads and decodes ISO track 2 (or center track) and transmits the data to
the host computer.
!D1
Reads and decodes ISO track 1 and transmits the data to the host computer.
!D3
Reads and decodes ISO track 3 and transmits the data to the host computer.
!O
Reads and transmits bit-by-bit data, from ISO track position 2 (or center
track), to the host computer. No decoding takes place in the TTPM2. A one
is transmitted as ASCII 1, and a zero as ASCII 0.
7. {, | and } was introduced in firmware version 3.2, and ~ in version 3.96
Note • The attributes in parenthesis only work for the !M command
{ (or *) Cancels the read-after-write function. The ticket is encoded and directly
transported forwards for separation (if applicable) and subsequent printing
according to the !F command data without prior read-after-write.
| (or $) Encodes the ticket, performs read-after-write, but does not transport the
ticket for printing. Instead, the ticket is backed into the active position
without being cut, waiting for the command to proceed, for instance, for a
decode operation.
} (or @) Expands the read-after-write operation. If this is successful, the ticket is
processed in accordance with standard routines, that is, it is separated and
printed. If the read-after-write operation is unsuccessful in the
programmed number of attempts, the ticket is transported forwards, and
the waste bin of the front load mechanism is activated (only printers with
front load & waste bin option). The ticket is dropped into a waste bin.
|} ($@) Combining the characters | and } results in normal behavior if the encoding
was successful. If an error occurs then the ticket is transported back to the
start position and NAK + ‘E’ is sent.
