	 * Channels is a bit field showing which channels the current sensor
	 * is capable of sending. If bit 0 is active, this sensor can send
	 * channel 0, if bit 13 is active, this sensor can send channel 13,
	 * etc. This bit can be active, even if the sensor is not currently
	 * sending this channel. Some sensors are configurable as to which
	 * channels to send, and this field only contains information on the
	 * channels available to send, not on the current configuration. To
	 * find which channels are currently being sent, monitor the
	 * Raw_time fields (pg. 19) in the raw_channels array (pg. 7). If
	 * the time is changing periodically, then that channel is being
	 * received.
