Make sure you have the adapter set to 3.3V and you only need 3 pins. The ground goes to the ground, but then you need transmit (Tx) to receive (Rx) and receive (Rx) to transmit (Tx). I use minicom in a Linux terminal with baud rate set to 1500000 and the adapter will be located on /dev/ttyUSB0. To adjust those settings in minicom, "sudo minicom -s" and save as dfl. You can also give your user permission to use minicom without sudo. "sudo usermod -a -G $USER dialout" then log out and log back in.
