Page 12: Input Modes
Product User’s Manual - 8. INPUT MODES When the SmartDriveDuo-30 is powered up, RUN (Left), ERR (Left), RUN (Right) and ERR (Right) LEDs will running once. After that, the input mode will be read from the DIP switch and retained as long as the driver is powered. If you wish to change the input mode, you will need to change the setting on the DIP switch and press the RESET button, or power cycle the driver (turn it off and turn it on again). - Page 13 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.
- Page 14 This is useful when a microcontroller is used to control the motor. The microcontroller does not need to send the pulse continuously to the SmartDriveDuo-30. Instead, it only needs to send a single pulse when the speed or direction of the motor needs to be changed.

- Page 20 When the driver is powered up and waiting for the header byte, the error LED will blink and indicate that there is input error. SmartDriveDuo-30 may take up to 500ms to start up after power is applied. Sending a dummy byte for auto-baudrate during this period may cause undesirable results. Please allow one-second delay between applying power and sending a dummy byte.
