Modify the built-in conversion board of TX900 to change RS232 to TTL (UART)
The wireless video data link modem default is TTL. Which is the core module of TX900, which is a long-range wireless video transmitter and receiver.
If the client does not have a specific requirement, the default data port of TX900 is RS232.
The flight control, Pixhawk, and the data port need TTL.
So how do we change the RS232 to TTL of the long-range wireless video data transmitter and receiver?
Please open the metal of the TX900, you will find the board like the one below.
The left side is TTL, there are more 6pcs zero resistors and no two chipsets.
The right side is RS232, there are more two chipsets and no 6pca zero resistors.

Modify RS232 to TTL (UART) by adding an external adapter board
Change RS232 to RS485
Because of the small size of the tx900, it is difficult to directly convert the RS232 to the RS485 module internally. If you need the RS485 data interface, we can add a converter box outside the box as shown in the picture below:
