2. Getting Started

The AE-CAP1 includes the two Target Boards, three Touch Application Boards, two 3 foot (91cm) USB Type A to

Micro-B adapter cables, a documentation and software DVD, and the QSG. To start working with the AE-CAP1, see the

included QSG.

On the Touch Application Boards, overlays are installed with plastic fasteners. Attempts to

remove and/or reinstall such elements may damage fasteners, boards, or board

components, and impact kit functional performance. Care should be taken if such removal

is undertaken, with plastic surfaced tools preferred to minimize damage or degradation to

the board and its components. Replacement of removed overlays will likely require new

overlay fasteners. See the BOM for part numbers.

Powering the AE-CAP1

Prior to providing power to the selected Target Board using one of the two power options, the power jumper J2 in the

“5V ONLY” labeled region of the AE-CAP1-S1 or S3 Target Board must be properly installed. For operation from the

USB Device 2.0 cable power, the lower two pins should be shorted together. For operation from the Barrel connector

input, the upper two pins should be shorted together.

The AE-CAP1 can be powered via two different methods:

•

Installation of a 5-V power source at the 5-V external power connection, J1, on the AE-CAP1-S1 or S3 Target Board.

Note that the outer sleeve of the barrel connector must be negative, and the center of the connector must be positive.

•

Connection of an external USB host to the USB Device 2.0 connector adjacent to the barrel jack on the AE-CAP1-S1

or S3 Target Board.

If power is available, a green LED located upper center on the Target Board should be lit, making that LED green. If the

J-Link MCU is active, it may light the red LED in the same package intermittently or solidly, making that LED appear

orange.

If the jumper is improperly positioned, connection of the USB Device 2.0 jack to a USB host does not power the Target

Board. Similarly, the 5-V barrel jack receives and uses power only if the jumper is appropriately positioned.

There is limited voltage protection on the 5-V direct power input: using a reverse-polarity barrel

plug power source may permanently damage the unit.
