The procedure is as follows:

① Input high voltage to RST pin. (100us ≧)

② Turn off (input low voltage) and wait 10ms.

4.9 Recommended conditions of communication

In case that this sensor and other sensors are connected with a common bus line, if you use this sensor at a communica-

tion speed more than 400kbit/s,

after finishing the communication with other sensors, we recommend to provide 1 ms or more waiting time

before starting the communication with this sensor in order to ensure a stable communication (see diagram below).
