Commander ACC Sound System Wiring
The Mini Commander ACC can operate in a special mode for controlling sounds
and couplers. Applications for this feature are targeted for adding a sound system to rolling stock.
Use the Mini Commander ACC when lighting is not directional, such as an
interior light in a caboose. To enable this mode of operation,
configure the Mini Commander as an ENG class, then press AUX1 + 0.
This modifies the behavior of the Mini Commander ACC outputs as follows:
HC1 and HC2 outputs are
controlled by the F and R keys respectively
Voltage and Timing on HC1 and HC2
are set to control coil couplers
P1 pin 1 is changed from MTRSEL to RailSounds signals
LC1 and LC2 control and operation
The diagram below shows the
connections to a Train
America Studios sound system.
ENG + ## + SET
AUX1 + 0
Note: For dummy engines, use the Mini
Commander Ex, which supports all TR (train) functionality.
