Before a station can be used, power (battery) must be supplied to it. To supply power to a station attached to a board, invoke cdiEnableBattery with the context handle to the board. This function connects the DC loop power to the station and enables the audio. cdiEnableBattery returns SUCCESS or an error code.
To disable power to a station, invoke cdiDisableBattery with the context handle to the board. This function removes the DC loop power from the station and disables the audio.
