Hi,
I'm not expert for this but as can see:
- on transmiter side is ST50 which have TTL(UART) output
- on receiver side is USB port
That mean you need UART to USB converter between this two parts.
You have USB to 485 converter, which is different protocol.
Solution is use UART/USB adapter which is very cheap and just connect red from ST50 to RX, and blue to GND.
Then set baud rate and other and that is must work.
Maybe(just maybe, and I'm not responsible) you can tray connect red(ST50) to T+, blue(ST30) to T- (like you describe in 3nd option of wiring) and T- also to GND of ST30.
Or 2nd option with R- also to GND of ST30.
