Hello?Jaroslav,
I do see your point. But it is not easy to do. First, the HL2 does not know if there is an ATU. The "No ATU" message appears if there is no IO board. And the bottom row with the "ATU" message is created before the PC can query the HL2 for the existence of the IO board. And since the query for the IO board relies on an I2C transaction over UDP, the time this will take is not known with certainty.
I don't want to complicate the code, so I am inclined to rely on the user to know if she has an ATU or not. At least the "ATU" label means that if the user has an IO board with an ATU attached, the control is there.
