Digital mode with UFR ESC:
This Digital mode offers additional advantages when using the sound module USM-
RC-3 in combination with our speed controller UFR:
• More accurate transmission of speed data.
• Additional outputs for lights. Whe
n using the combination, we recommend
controlling lights with the UFR. In case more lights are required at the UFR,
additional light outputs from the USM-RC-3 can be used. The corresponding output
functions must be set in the USM-RC-3 Sound-Teacher.
• Whe
n indicator lights are activated at the UFR, the sound module plays
simultaneously the indicators sound.
When using “Digital mode with UFR ESC” it is also necessary to activate the option
in the Drive Teacher: Configuration
Speed controller
“
Digital communication

”.
However, there is one limitation in this operating mode: The EasyBus light boards
from Kraftwerk can no longer be controlled via the sound module when the digital
transmission is activated.
Analog mode:
The Analog mode should be used, if you don’t have „standard” RC equipment, that
means your receiver does not use standard proportional channels (1.0 – 2.0 ms
signals).
In the Analog mode the driving speed is determined by a voltage measurement at
one or two motors. In order to activate additional sounds or to turn on/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 Analog mode. For example, only a maximum of 8 functions can be
triggered via the switching inputs.
Mix mode:
The Mix mode is a combination of Digital and Analog mode. Like in the Analog mode
the driving speed is determined directly by the motor voltage. However, the
proportional channels #1 - #8 still working in Digital mode and can interpret signals
from 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.
