Rangefinder port

Hi, i am currently using pixhawk4 and i plan to use 5 range finder (4 for facing each side and 1 for facing downward)
if i use i2c splitter to connect it how i can know what my sensor address in configure my parameter for rangefinder
or is there any other suggestion to connect all my 5 rangefinder ?

Good day, what kind of rangefinder are you using on i2c?
Just consider that if you are using the same sensors you need change the I2C address for each sensor coz share same address can give you conflicts.
