The frequency of the flashes is proportional to the servo period (the amount of time between pulses on a single channel) with a period of 20 ms the flashing occurs approximately once per second. Once the Maestro is ready to drive servos, the yellow LED will periodically flash briefly. During this time the Maestro does not transmit any servo pulses. When the Maestro is in auto-baud detect mode (the default) and has not yet detected the baud rate, the yellow LED will blink slowly. The yellow status LED indicates the control status.The red LED can also be controlled by the user script the red LED will be on if there is an error or if the script command for turning it on was run. See Section 4.e for more information about errors. The red LED turns on when an error occurs, and turns off when the error flags have been cleared. The red error/user LED usually indicates an error.The control center application constantly streams data from the Maestro, so when the control center is running and connected to the Maestro, the green LED will flicker constantly. After the Maestro gets this message, the green LED will be on, but it will flicker briefly when there is USB activity. The blinking continues until the Maestro receives a particular message from the computer indicating that the Maestro’s USB drivers are installed correctly. When you connect the Maestro to USB, the green LED will start blinking slowly. When the Maestro is not connected to a computer via the USB cable, the green LED will be off. The green USB LED indicates the USB status of the device.
