8.1 RC (Radio Controlled) 
In RC input mode, the speed and direction of the motor is controlled by the signal from the 
standard hobby radio control transmitter and receiver, or a microcontroller generating the 
similar signal. 
NOTE 
The RC transmitter must be ON before power up the SmartDriveDuo-30. 
RC  Input  mode  is  selected  by  setting  the  SW1  &  SW2  to  0  (Down).  SW3 –  SW6  can  be 
configured depending on the requirement of the user.

MIXED 
The motor speed is controlled by channel RC1 and direction is controlled 
by channel RC2. Recommended this mode if controlled using RC 
transmitter/receiver. 
INDEPENDENT RIGHT 
Only motor Right will active, motor Left will inactive. Motor Right is 
controlled by channel RC2. 
INDEPENDENT LEFT 
Only motor Left will active, motor Right will inactive. Motor Left is 
controlled by channel RC1. 
INDEPENDENT BOTH 
Both motor is active and can be controlled individually through channel 
RC1 and RC2. Recommended this mode if controlled using 
Microcontroller. 
Exponential 
Mode 
SW5 
0 
1 
OFF 
The speed is linear with the input signal. This is for low to medium speed 
motor. 
ON 
The response to input is exponential and thus soften the control around 
the center zero speed point. This is suitable for high speed and very 
sensitive motor. 
MCU Mode 
SW6 
0 
OFF 
The center point will be calibrated upon power up. Timeout occurs after 
lost of signal for 100ms and the motor will be stopped for safety 
purpose.
