Operating Modes: Digital- and analogue operation
In order to make the sound module as universally usable as possible, 2 different
operating modes are available. Since the operating mode is very decisive for the
possible functions, and particularly for the connection of the sound module, it should
be decided now at the beginning, which one of the two operating modes is better
suitable for the respective model. The operating mode of the sound module, is set in
the USM-RC Sound-Teacher (see page 32).
If possible, always the digital operation should be used, because this offers more
functions than the analogous operation.
Digital operation:
The digital operation will be presumably always be used if you use standard RC
remote control radios and receivers with PPM-signals. Here is the sound module
connected directly to the RC-receiver, and it recognizes the driving speed directly
from 1 or 2 proportional channels (parallel to the speed controller). Via 2 more
proportional channels, up to 12 additional sounds can be played, the engine sound
can be switched on and off, the volume can be adjusted, also light and indicators can
be switched. Via digital switching inputs also another 4 more additional sounds can
be played.
Analogous operation:
The analogous operation always becomes used, if you didn’t have a “standard” RC
equipment.
In the analogous operation the driving speed is determined by a voltage
measurement of 1 or 2 motors. In order to activate additional sounds, or turn on and
switch off the engine sound, the digital switching inputs of the sound module must be
connected here (e.g. with switching modules).
Because of the missing proportional channels, as many functions unfortunately are
not possible in the analogous operation, as in the digital operation. So for example
you can only activate 6 additional sounds with 6 switching inputs. Also the light and
the volume cannot be switched or controlled here by the remote control.
