HISTORY
Functions and features are being added from time to time affecting the firmware in the
TTPM2. The following table lists the changes of general interest.
The TTPM2 firmware, residing in programmable read-only memory (PROM), is available
in several customized versions. They differ only in minor details and are indicated by
three letters. You will find these letters on the label attached to the PROM component.
The standard version, for example, has the letters STD.
The standard version includes support for one consecutive ticket stock track, one rear
single-ticket entry, and the front load option. Please note that only some of the FW ver-
sions after release 2.13 have built-in support for either two consecutive ticket entries or
one consecutive ticket plus one single-ticket entry.
Single track printer PROMs are marked FW906-260, where 90
6
indicates single track and
260 indicates revision 2.60.
Dual track printer PROMs are marked FW907-234, where 90
7
indicates dual track and
234 indicates revision 2.34.
From firmware version 2.70, all firmware is 906-xxx, and you select single track, dual
track, or CD version with the dip-switches on the control board.
Notice that further FW revisions may have been introduced since the issue of this edition
of the TTPM2 Installation and Programming Manual. An up-to-date list of FW revisions
can be read at the Swecoin web site at http://www.swecoin.se.
