QUESTION: Can I run two MAX173xx eval boards simultaneously with one PC? If so, do I need two instances of the GUI?
ANSWER: Yes, you should be able to run and log multiple EVKITs on the same PC. Start with one EVKIT connected, start the first instance of the GUI, click on the Commands tab, and select a unique log file. Then connect the second EVKIT and start the second instance of the GUI. Then also give a new log file. Both EVKITs have the communication lines isolated to prevent ground loop issues through communication.
