Re: Red and yellow signal

From the manual:

Quote:
To calibrate the servo-style PWM input for a specific range, connect a PWM source, then:
1. Hold down the USER switch with a straightened paperclip for 5 seconds.
2. The LED flashes Red and Green to indicate Calibration mode.
3. Instruct the controller to send a full-forward signal for one or more seconds.
4. Instruct the controller to send a full-reverse signal for one or more seconds.
5. The LED flashes Green and Yellow quickly to indicate a successful calibration.
The MDL-BDC24 samples these signals and centers the speed range and neutral position
between these limits. A calibration failure signals if an out-of-range signal is detected. This
condition is indicated by flashing the LED Red and Yellow.
I don't recall the calibration reset procedure (I believe the PWM has to be disconnected for it to work), but I would suggest using this procedure to recalibrate them.

Note that steps 3 and 4 are logically equivalent to throwing the joystick to full forward and full backward (provided your PWM connection and relevant programming is done correctly).
