1. A system, comprising:
a first controller having 8 available first controller output lines comprising a first subset of 4 first controller output lines; a second controller having 4 second controller input lines and 16 second controller output lines, the 16 second controller output lines electrically connected to a first set of ultrasonic transducers; the first controller adapted and configured to receive a 16-bit ultrasonic transducer control signal, separate the 16-bit ultrasonic transducer control signal into four 4-bit intermediate ultrasonic transducer control signals and send each of the 4-bit intermediate ultrasonic transducer control signals to the second controller through the first subset of 4 output lines; and the second controller adapted and configured to receive each of the four 4-bit intermediate ultrasonic transducer control signals through the 4 second controller input lines, to accumulate the four 4-bit intermediate ultrasonic transducer control signals, to reassemble the 16 bit ultrasonic transducer control signal based on the received four 4-bit intermediate ultrasonic transducer control signals and to send the 16-bit ultrasonic transducer control signal through the 16 second controller output lines to the first set of ultrasonic transducers. |
