The NASA AIS puts out a sort of RS232
I use a serial to USB adapter myself ( prolific chipset )
Your adapter is NMEAv2 to USB
You can try R(eceive) + and -
Pin2 -> R+
Pin5 (shield) -> R-
If it does not work you can try to connect NASA pin5 (shield ) to GND instead of R-
Either may work.
Googling RS422 vs RS232 can provide more technical info since NMEAv2 is electrically RS422
