3 Documentation
This documentation relates to the hardware and firmware status at the time of
editing this manual� The features of the devices are continuously developed further
and improved�
3.1 Firmware and hardware status
3.1.1 Downward compatibility
The modules are downward compatible� Older modules cannot, however,
feature the same characteristics as new module versions� However, existing
characteristics have been retained so that older modules can always be replaced
with the new ones�
The documentation describes the differences between the modules�
The firmware and hardware status of the modules can be taken from the version
number printed on the side of the module� The version number can be identified by
the prefix "D"�
