Function sequences
All functions that can be triggered with the sound module (see page 24) can be
compiled to a special function sequence with defined order and time for each step.
More information can be found in this manual starting on page 84.
Battle unit
A battle unit can be used to organize tank battles with infrared rays.
A battle system consists of an IR transmitter and an IR receiver. The connection is at
X16. The plug is compatible with the battle units from Heng Long and Torro/Taigen.
Setting of battle unit:
To activate the battle unit in your Sound Teacher see page 54.
Two different systems are supported:
• Torro/Taigen
• Heng Long
The sytems are not compatible with each other, due to different transfer protocols.
How to shoot:
An infrared shot is activated with the function „Additional sound“ – „Cannon shot“.
It is also possible to activate an infrared shot using input X15/2. A gun recoil unit with
a switch for this function can be connected to this input as well.
Sounds for hits and destruction of the tank:
Different sounds can be played when the tank is hit or destroyed. For this, the
additional sound slots "Battle Unit - hit" and "Battle Unit - destroyed" need to be filled
with a sound.
After 5 hits the tank is "destroyed" and the driving sound is switched off.
Voltage monitoring
The connected supply voltage at X1/A+ and X1/A- is measured permanently. If the
voltage drops below an adjustable value for longer than 10 seconds, different actions
can be triggered:
• Playback of a warning sound at empty battery (e.g. „Please load battery“)
• Playback of a warning sound at undervoltage (e.g. “Attention undervoltage“)
• Switch off the sound module
• Switch off all outputs
