Wiring mid40 and uINS

Buddelflink

Hello,
I have not seen anywhere a picture with a detailed wiring of the Livox md40 and the rugged uINS from InertialSense. Can someone tell me if I am doing it right or point out any errors?
Thanks a lot

1. You can try grounding the TTL to 485 module and uINS .
2. Have you written code that allows the Ethernet cable to transmit GPRMC signals.

Thank you for taking the time....
1) I have done that now. Also, a ground line has been drawn between uINS and RPI4. The uINS gets current from the RPI.

2) No, the Ethernet cable is only shown because it transfers the point data from the Livox to the RPI. I thought the GPRMC signal comes from PIN-7(uINS) and can be connected directly to the RXD (UART) from the RPI.

hello i am also interested in connecting my mid40 with an external imu + gps, this link you put on the forum is working with inertial sense and what software do you use, the official ros-drive and livox libraries with ubuntu 18.4 installed on raspberry? I have installed the whole package on a virtual machine but without the imu the clouds are broken and distorted you have found a decent solution with this imu? Livox together with dji had already used this system but I never found the connection diagram.
Can you help me add this imu with gps? does the system insert the IMU data in addition to the GPS data? Thanks .
