1. Resetting the integrated MD4 modem to its default settings, for example, to reactivate the
modem when it no longer reacts.
2. Theoretically, there are four different settings possible for a standard profile. The
integrated MD4 modem is, however, always operated with profile 0 (all switches set to
OFF)!
Note
The MD4 modem adopts the settings at the DIL switch only when the 24 V DC power
supply is turned on. While the settings are being adopted, the MD4 indicates this by the
four lower LEDs lighting up in sequence. As soon as the LEDs stop lighting up, the reset
and adoption of the set standard profile is completed.
