Isolated/Standalone – Used to protect the host PC while debugging the application, which may present
dangerous voltages to a PC or when the user wants to run a standalone application with a single
supply. Power for the entire system (both LaunchPad and LED BoosterPack) is supplied from the 12 V
AC/DC wall adapter. The USB can be optionally connected if the user wants to debug the application;
in this case, power for the emulator is supplied via USB. This mode provides the user with 2500 Vrms
of isolation to protect the computer in the event that dangerous transient voltages are present on the
board.
– Jumpers JP1, JP2, and JP3 on the LaunchPad should NOT have jumpers placed on each post.
– Jumpers J2 and J8 on the LED BoosterPack should have jumpers placed on each post.
– Connect the USB (optional, only used for debugging) to the LaunchPad.
– Connect the included power adapter to the LED BoosterPacks' J1.
