A technique for serially controlling an array of optical sensor chips over a pair of signal lines. After broadcasting an initializing reset command to all chips over serial lines, a determine-address command is broadcast to commence unique address determination. On subsequent clock signals, each chip locks its address into an on-board register. Following this process, each chip can be addressed individually. Subsequently, when each array chip is directed to read data out, the data is output to a single common bus line to the controller. Alternatively, individual chip outputs may be connected directly to the controller, or the outputs of odd and even chip pairs may be tied together for broadcast readout of all odd chips or all even chips.
