Stop bar
Apart from the missing start character and the different stop character, the table is identical to that of
Code 2/5 Interleaved.
5.2.2.9 2/5 Siemens (optional)
The Code 2/5 Siemens (or more correctly Siemens Code PT80) is derived from the Code 2/5 3 Bar
Matrix. This code can be found on the rail tickets of the Deutsche Bahn AG. The data characters are
coded into bars and spaces in the same way as the 2/5 3 Bar Matrix. The character table has been
changed from the initial code 2/5 3 Bar Matrix. There is no start character. The stop character is only a
thick bar. Due to the missing start character and the rudimentary stop character, this code must be
activated separately for measurement. The 2/5 Siemens Code is normally used as a two-track code.
Track 1 is a code with 4 characters. Track 2 is a code with 2 characters and one bar at a distance of
55 mm in front of the actual code (called FF bar).
Specification of symbology and code contents
SYMBOLOGY : 2/5 SIEMENS
CODE : 9678
Size information
Apart from the ratio specification, no size information is given. The thin bars must have a dimension of
1.5 mm, and the wide bars 3.4 mm (Ratio approx. 2.27 : 1). If the code deviates from this ratio, the
information for bars and spaces is shown with the correspondingly large deviations.

(only for track 2 !)
The bar and space specifications are the extreme values. The system is identical to the display for the
other symbologies. The Character specification refers to 3 bars with the intervening spaces, 2 wide
and 3 narrow elements are always used. This produces a consistent character width. This combination
of bars and spaces produces a number on decoding. The average value is as usual determined from
the individual bar deviations. The "Symbol" specification refers to the complete barcode. If the size
ratios are incorrect, this can be read off from this value.
