Cabling configuration using livox convertor and avia

[gc625-kodifly]

in the readme it said that PIN 11 is connected to RS485_B and PIN 12 is connected to RS485_A. I am using the livox convertor with the sync cable, so I just want to confirm whether RS485_A corresponds to pin 2 on the sync cable and RS485_B corresponds to pin 1 on the sync cable

edit:
Furthermore, previously the stm pins were connected like so
PIN 11 <-> STM32 PWM- GND
PIN 12 <-> STM32 PWM+ PB5

in the updated schematicwith the ttl to rs485 convertor:

should the connection be like so:
STM32 PWM- GND <-> TTL-RS485 GND
STM32 PWM+ PB5 <-> TTL-RS485 TXD?

Finally, it also mentioned STM32 TXD (GPRMC) is converted from TTL to USB and sent to the PC, By STM32 TXD, are you referring to PA9, or am I misunderstanding something? Is TXD and GND the only two pins needed to be connected to the USB to TTL convertor?

You can refer to these cabling configuration pictures.
If you use the converter2.0, follow this:

If you connect LiDAR directly to the STM32, follow this:

In our setup, LiDAR is directly connected, but both options are possible. Using a converter is more convenient.

If you are using a converter, you can directly connect the TTL level generated by the STM32 to the sync cable. The RS485 conversion mentioned in the readme is not needed.
