7 Power Modes

The DLP Controller can operate in Normal or Standby power modes. Use Set Power command to toggle between the two modes. In the standby state the controller will be consuming the minimal power. When the system is not in use, user can set system in Standby state. Note the state transition may take several hundred milliseconds to complete. User shall ensure power mode transition is complete using Get Power Mode command.
