J63 J12 J64 JP1 K2G GP EVM K2G Audio Daughter Card Connecting the K2G Audio Daughter Card to the K2G general-purpose (GP) EVM. 1 2 Mounting the Audio Daughter Card onto the K2G GP EVM: • Align the pins of daughter card (J63 and J64) with the main card (J12 and JP1) respectively: See image above and press gently to mate the connectors at the corners. 3 Mounting the Audio Daughter Card onto the K2G GP EVM (continued): • Press the Audio Daughter Card connectors in the middle carefully to ensure mating at the center. See image above. • Apply pressure on middle and the sides evenly to ensure proper mating of the connectors. 4 The board looks as shown after mating the K2G GP EVM and Audio Daughter Card. Powered speakers Input (12V/5A) Switch SW1 Analog output Analog input from media device 5 Powering the K2G Audio Daughter Card: • The K2G Audio Daughter Card is powered from the K2G GP EVM through the expansion connectors. After mounting the Audio Daughter Card and connecting all audio sources/speakers, connect the 12V/5A adapter to the J3 connector on the main board. Slide the switch SW1 on the GP EVM into the ON position. Once the GP EVM has booted, it is safe to turn ON any powered speakers. TI Worldwide Technical Support Internet TI Semiconductor Product Information Center Home Page support.ti.com TI E2E™ Community Home Page e2e.ti.com Product Information Centers Americas Phone +1(512) 434-1560 Brazil Phone 0800-891-2616 Mexico Phone 0800-670-7544 Fax Internet/Email +1(972) 927-6377 support.ti.com/sc/pic/americas.htm Europe, Middle East, and Africa Phone European Free Call International Russian Support 00800-ASK-TEXAS (00800 275 83927) +49 (0) 8161 80 2121 +7 (4) 95 98 10 701 Note: The European Free Call (Toll Free) number is not active in all countries.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof.
