Operating Modes: Digital, Analogue And Mix Mode - beier USM-RC-2 Operating Manual

D Sound module USM-RC-2

Operating Modes: Digital, analogue and mix mode

In order to make the sound module universal usable, 3 different operating modes are
available. The operating mode is very important for the possible functions and
especially for the connection of the sound module. Therefore it should be decided at
the beginning which one of the two operating modes is better suitable for the used
model. The selected operating mode of the sound module is set in the USM-RC-2
Sound-Teacher. (see page 56).
If possible, please use the digital or mix mode, owing to their extended selection of
functions.
Digital mode:
The digital mode is always applied if you use standard RC remote control radios and
receivers (for example 35MHz, 40MHz or 2,4GHz). In this case the sound module is
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 or 3
additional proportional channels (and the 4 switching inputs) it is possible to control
different functions of the sound module (see page 57).
Analogue mode:
The analogue mode is used, if you don't have „standard" RC equipment, that means
your receiver does not use standard proportional channels (1,0-2,0ms signals).
In the analogue mode the driving speed is determined by a voltage measurement at
1 or 2 motors. In order to activate additional sounds or to turn on and switch off the
engine sound the digital switching inputs of the sound module must be connected
(e.g. with switching modules).
Unfortunately due to the missing proportional channels, a few functions are not
possible in the analogue mode. For instance you can activate just 4 or 6 additional
sounds with the switching inputs.
Mix mode:
The mix mode is a combination of digital and analogue mode. Like in the analogue
mode the driving speed is determined directly by the motor voltage. However, the
proportional channels #2 - #4 still working in digital mode and can interpret straight
signals of the RC receiver.
The mix mode is used, if the speed controller has special functions such as cruise
control and that's why the controlling of the drive motor is different.
