3. Hardware Setup
3.1. Using the MCU Card Alone
Refer to Figure 2 for a diagram of the hardware configuration when using the MCU card without a UDP
motherboard.
1. Connect the USB Debug Adapter to the 10-pin debug connector (J23) on the MCU card using the 10-pin
ribbon cable.
2. Connect the USB Debug Adapter to a USB Port on the PC.
3. Move the SW1 VDD Select switch to the top +3.3V_VREG position.
4. Verify that the JP2 Imeasure jumper is populated.
5. Power the MCU card through the power connector (J6) using the supplied 9 V ac/dc adapter.
Notes:
Use the Reset button in the IDE to reset the target when connected using a USB Debug Adapter.
Remove power from the MCU card and the USB Debug Adapter before connecting or disconnecting the
ribbon cable from the MCU card. Connecting or disconnecting the cable when the devices have power can
damage the device and/or the USB Debug Adapter.
