Timing Chart During Communication

During communication, the timing chart is shown below.
● Collision detection is not performed (P to P connections only).
● The baud rate can only be changed by operating the sensor. It cannot be changed by way of
communication commands or LS-Navigator.
● A time-out will occur if the send time of the command exceeds 2 seconds.
● Response time to the command varies depends on the baud rate.
