4. The USB-to-I
2
C/SMBus/PMBus Controller may be
plugged into any board. If no DC1962C boards show up
in the GUI, click the magnifying glass icon to enumer-
ate the I
2
C bus and find the addresses of the parts. Go
to step #2 to ensure that each board has a unique DIP
switch setting.
5. Since the individual CONTROL lines are connected
across the boards (CTRL is a common signal across
all boards in the array), make sure that all CONTROL
switches are set to the RUN position.
6. Re-launch LTpowerPlay. After launching, LTpowerPlay
will enumerate the entire board array and build a rep-
resentative system tree and read all hardware settings
into the GUI.
ATTENTION: Once the GUI has launched, click the “RAM
→ NVM” button in the tool bar to ensure that the slave
addresses are retained after a power off or reset. Other-
wise you may lose communication with the slaves after a
power cycle or reset event.
