Input data
Table 10.19: Input data for modules 21 … 27
Input data
2 bytes consis 4..28 bytes of bar code information depending on the module
Output data
None
Remarks
The remarks for module 20 – decoder state, apply in an analogous manner. In addition, all bytes beginning
with address 1 are reset to the init. value.

a) Attention: This does not necessarily correspond to the state at the time the bar code is scanned
b) If the bar code information (bar code and, possibly, other items such as the check sum) fits in the selected module
width, this value reflects the length of the transmitted data. A value larger than the module width indicates a loss of infor
-
mation caused by a module width which has been selected too small.
