Setting Up the Hardware 2.1 Setting Up the Hardware To set up the hardware provided with the EVM, use the steps in the sections that follow. You may skip sections if you do not need to access a particular peripheral. For example, if you do not need to use the serial cable, skip that section. 1) The EVM is sensitive to static discharges. Use a grounding strap or other device to prevent damaging the board. Be sure to connect communication cables before applying power to any equipment. 2) If you us

Setting Up the Hardware 4) Connect the red and white audio cables to the EVM Audio Output and the LCD display R/L Audio Input jacks as shown below: 5) Connect the BNC-to-RCA connector to the coax cable. Then connect the coax cable to the video camera and the EVM Video Input. 6) Connect the power jack for the video camera. To be ESD safe, do not plug in the other end of the camera power cord until the later step that instructs you to do so. See Section A.1, Changing the Video Input/Output Methods
