synchronization.
Note:
Sensor response times will increase proportionally to the number of sensors that are in the synchronization string. This is a result of the
multiplexing of the ultrasonic transmit and receive signal and the resulting increase in the measurement cycle time.
Note:
The sensors syncronization input delivers an output current in case of low level and burdens with its input impedance in case of high level. Please
pay attention that the synchronizing device needs to have that driver capability:
driver current against +U  n * high-level/input impedance (n = number of sensors to be synchronized)
B
driver current against 0V  n * output current (n = number of sensors to be synchronized).
