Yes that seems correct. The A0 - A3 pins are not for the relays (output), they are predefined to be input pins.
If you are just playing, any old on/off switch can be used to test the input pins. Connection outlined in previous reply.
Send a open request from the driver, that should result in the N1 relay activating. wait a bit then close the switch connected to A0. You will see the INDI driver change to the opened state.
