Pixhawk 2 Cube Black RNGFND problem

Pixhawk 2 Cube Black RNGFND problem

MB1240 XL-MaxSonar-EZ4 -> ADC port
LidarLiteV3-I2C -> I2C 2 port

When I set it up like this,
Which one is RNGFND?
I don’t know which one is RNGFND2.

Is there a way to check it out?

And if you look at the RangeFinder list,
There’s only one.
Can you make two come out
