3.4.1. Set Up the Hardware

The first stage of the demonstration is hardware setup.

To set up the hardware, follow these steps:

  1. Connect the Bitec DisplayPort FMC daughter card (revision 8C) to the Intel Agilex® 7 development kit at FMC port A.
  2. Connect the Intel Agilex® 7 development kit to your PC using a USB cable.
  3. Connect a DisplayPort cable from the DisplayPort RX connector on the Bitec DisplayPort FMC daughter card to an HDCP-enabled DisplayPort device, such as a graphic card with DisplayPort output.
  4. Connect another DisplayPort cable from the DisplayPort TX connector on the Bitec DisplayPort FMC daughter card to an HDCP-enabled DisplayPort device, such as a display monitor with DisplayPort input.
