Operation mode Control
(MI4M)
(Automatic gain control)
In this operating mode, a control loop is set up in conjunction with external measuring microphones,
modules
The program is always active in this operating mode and reacts to measurement value telegrams of the
assigned
MI4M
(30h telegrams).
Switching thresholds for the permanently-assigned level values are calculated from the reference and
correction values. By comparing the measurement values with the calculated switching thresholds, the
program determines a level value and allocates this value to the amplifier.
The measurement values must be requested at each announcement by the
MI4M
via
Line
1.
Flag (NAND)
