7.2.2 Establishing the data connection
1. Start FieldCare.
2. Establish a connection to the Commubox. To do so, select the "CDI Communication
FXA291" ComDTM.
3. Then select the "Liquiline CM44x" DTM and start configuration.
You can now start online configuration via the DTM.
Online configuration competes with onsite operation, i. e. each of the two options blocks
the other one. On both sides it is possible to take away access from the other side.

• In the DTM the menu structure corresponds to the onsite operation. The functions of the
Liquiline soft keys are found in the main window on the left.
• Clicking a menu name or a function corresponds to pressing the navigator.
• You can make your settings conveniently via the computer keyboard.
• You can use FieldCare to save logbooks, make backups of configurations and transfer
configurations to other devices.
• You can also print out configurations or save them as PDFs.
