1.5.1. Connection and Settings Guidelines
Before programing with the .sof file, ensure that the connections and settings are correct.
- For parallel loopback design, the on-board BNC RX connector (J1/12G In) connects to an external video source and the on-board BNC TX connector (J2/12G Out) connects to a video analyzer.
- For serial loopback design, the on-board BNC TX connector (J2/12G Out) connects to an on-board BNC RX connector (J1/12G In) or a video analyzer.
- Ensure all switches on the development board are in default position.
- The SDI video analyzer displays the video generated from the source.
Note: For parallel loopback designs, change the jumper (J8) position before switching between fractional frame rate and integer frame rate video formats. Press the push button (PB1) to trigger a device (LMK03328) power cycling through the PDN pin every time you change the jumper (J8) position.
