Parallel Quattro II auxiliary connections

When you have more than one Quattro II 48/5000 in parallel -- two in my case, master and slave -- what happens with the programmable relay outputs, the analog/digital input/output ports, and the temperature/voltage sense inputs?

Do you only use the ones on the master and ignore the ones on the slave, connect both in parallel, or do they appear duplicated so you get twice as many ports -- for example, two independent relays?

Relays and digital inputs are individual to each inverter and can be utilized by using the appropriate assistant or virtual switch in each inverter. As for the temp sensors, I believe you should only use the temp input in the master and not the slave. If I am mistaken I'm sure someone will correct me shortly.
