Using sonar on lumenier LUX H7

[hi6otb (Hiro)]

I want to use maxbotix 1240 on lumenier LUX H7.

LUX-H7-User_Manual_v1.pdf

Anyone know how to use it ?

I tried three different ways.
・Maxbotix serial
(connect to TX4 RX4, SERIAL6_, Baud = 9, Protocol = 9, RNGFND_TYPE = 13)

Maxbotix ultrasonic sensor with serial port

Hello, I attach some photos. The specific sensor is the LV-MaxSonar EZ4 MB1040, tucked away in the data sheet for it is the information that it inverts the serial line, and this is why the inverter is implemented. As demonstrated, it works fine with this if plugged in. I’m not using the ttyOx port, but the ttyS5 port, referencing this as ttyO5 doesn’t work. Ardupilot doesn’t seem to find it at all, so apmplanner2 doesn’t display or put it in the status bar. thankyou very much for your help! […

・Maxbotix analog
(connect to CU2, rngfnd1_PIN = 7 or -1)

・Maxbotix I2C
(connect to DA CL)

However, rndfinder or soner range do not show any output.
