3.2. Using the MCU Card with the UDP Motherboard
Refer to Figure 3 for a diagram of the hardware configuration when using the MCU card with a UDP motherboard.
1. Connect the MCU card to the UDP motherboard slot.
2. (Optional) Connect the I/O card to the UDP motherboard slot.
3. (Optional) Connect a radio card to the radio card slot in the UDP motherboard.
4. (Optional) Connect an EZLink card to the EZLink card slot in the UDP motherboard.
5. Connect the USB Debug Adapter to the 2x5 debug connector on the MCU card with the 10-pin ribbon
cable.
6. Connect one end of the USB cable to the USB connector on the USB Debug Adapter.
7. Connect the other end of the USB cable to a USB Port on the PC.
8. Connect the ac/dc power adapter to power jack J20 on the UDP motherboard. The board can also be
powered from the J16 USB or J1 mini USB connectors.

Notes:
 Use the Reset button in the IDE to reset the target when connected using a USB Debug Adapter.
 Remove power from the target board and the USB Debug Adapter before connecting or disconnecting the
ribbon cable from the target board. Connecting or disconnecting the cable when the devices have power
can damage the device and/or the USB Debug Adapter.
 The MCU card can be used alone without the motherboard. However, the motherboard must be powered if
an MCU card is connected.
