USB to Serial RS232/UART TTL/RS485 DB9 Adapter Converter Module for FTDI FT232BM/BL Can the module serve as both a downloader and a communication installer?

Question

Electronics

via USB-UART TTL downloaded the program to the device, everything worked out. There's also USB-RS232 (DB9) and an RS485 VCC GND port. How can these two ports be used? To establish a connection? Or also as a bootloader or both?

Answer 1

To establish a connection?

Very likely.

Or also as a bootloader or both?

Maybe a bootloader.
PS And it is not quite clear "who stood on whom". All this zoo of 232 and 485 - refers to an unknown device or to the same converter on the FT232?
