FW revision Change
2.33
The data string sent to the TTPM2 to encode track 2 (!M) can now have a check-
sum digit added to it. This checksum will then be compared by the TTPM2 before
encoding which guarantees that the magnetic code data is correctly received. See
page 35.
Combining the characters $ and @ in the !M data string now results in normal be-
havior if the encoding was successful. If an error occurs then the ticket is trans-
ported back to the start position and NAK + ‘E’ is sent.
Adding a single digit after the !P makes it possible to set the maximum number of
encoding retries for one ticket. The number given is the number of additional tries
i.e. !P 1 means one normal attempt plus one retry. Default is 1, which is the value
used if no digit is present.
SGA version:
Various modifications to the paper load routines have been made.
A paper jam during encoding no longer causes the printer to loose data.
2.34
Some types of long tickets caused paper jam if the magnetic encoding failed. This
is corrected by not allowing the long ticket to enter under the print head before
checking the magnetic code.
2.35
Filter included making it possible to use tickets with holes.
2.36
!L3 also supports tickets with holes.
!L3 speed improved.
2.37
Test version, never released
2.38
Bug found which caused the magnetic code to be erased if a ticket was reprinted
without any magnetic data.
2.39, 2.40
Bug found in the !L4 routine. Rear motor now runs a bit longer to avoid jam after
cut.
A new error code is defined "E" which means jam in the input feeder during an !L3
command.
Paper jam in the input feeder was previously reported as "D", which gave the same
error code for two different jam situations.
2.41, 2.50
The limit between long ticket and short ticket has been moved to approximately
95 mm instead of just below 110 mm.
This version is intended primarily for the dual track version (SWC907-XXX).
