The controller is equipped with a serial interface that is used in the works for
communication during calibration. The interface may also be used to set up

network via a special cable and Modem. In this way, for example, a rapid diagnosis
can be made in case of problems. You can obtain more details on this service option
via the contact address given in 1.2.
