1. A method, comprising:
- coupling a plurality of sensors to a data transmission bus and a command line;
transmitting a marker across the command transmission line;
sensing the marker at each of the plurality of sensors;
at each of the plurality of sensors, transmitting data over the data bus at a predetermined time from the marker, such that each predetermined time for each of the plurality of sensors is different from the predetermined time at the other sensors, and such that data transmitted from each of the plurality of microphones does not interfere with data transmitted from others of the plurality of sensors.

Abstract
A plurality of sensors are coupled to a data transmission bus and a command line. A marker is transmitted across the command transmission line. The marker is sensed at each of the plurality of the sensors. At each of the plurality of sensors, data is transmitted over the data bus at a predetermined time from the marker. Each predetermined time for each of the plurality of sensors is different from the predetermined time at the other sensors. Data transmitted from each of the plurality of sensors does not interfere with data transmitted from others of the plurality of sensors.
