I am reading the sonar sensor spec and found the following sentence:
Quote:

Each 49mS period starts by the RX being high or open

Does it mean if I connect the RX pin to a digital output channel, I can inhibit the ping indefinitely by pulling RX low until I need to read the range. Then I would raise RX back to high and wait 50ms before reading the analog value? Without doing this, it seems the sonar sensor will ping continuously at approx. 50ms period. Am I reading this correctly?
