Display Statuses in Detail
The AS-i slaves are displayed in groups of five. The three group LEDs indicate
which group of 5 is being displayed in binary code. The 5 LEDs of the slave display
then indicate the detected or active AS-i slaves within the group.
To find out which slaves are active, select the group of 5 (line) corresponding to the
lit group LEDs. The currently lit LEDs of the slave display then indicate which
slaves within this group are currently active.
If a group of B slaves is displayed, the “B” LED is also lit.
