After having mounted the modules and switched on the voltage of the central unit, ibaDAQ detects the modules and checks the firmware version.

ibaDAQ has a so-called "overall release version". This version contains the current firmware version of the central unit as well as the firmware versions of the modules.

The overall release version is displayed in ibaPDA in the "Info" tab (here referred to as the "firmware version").

When the firmware version of a module does not match the "overall release version" of the central unit, ibaDAQ does an automatic upgrade or downgrade of the module. After that the module is ready for use.

Note
	The device must not be switched off during an auto-update.

Note
	The "overall release version" contains all modules known until then and the corresponding firmware versions. If a module is not yet known (i.e. it is more recent than the central unit's firmware version), this module is ignored and not displayed in ibaPDA. In this case, a new update file has to be installed for the "overall release version". Please contact the iba support.
