3 Test Procedure

Upon gathering all essential HW/SW, turn on the computer module and monitor to verify that both are working properly and configured to act as the HDMI 2.1 signal source and sink, respectively. Upon powering up the computer module and monitor, proceed to integrate the TMDS1204EVM into the test setup.

The following test procedure assumes that the TMDS1204EVM is in the external I2C configuration. However, the AEQ functionality can be used in both pin strap and I2C modes but for convenience of demonstration we use I2C mode in this procedure. To set the EVM to I2C mode, leave JMP 4 pins 4 and 6 unconnected. To integrate the EVM into the test setup and use AEQ functionality, do the following:

  1. Insert the +5 V DC power source into the barrel jack. Turn on SW2.
  2. Configure TMDS1204 using the I2C bus as described in the AEQ configuration section.
  3. Insert an HDMI source using a standard HDMI cable into P1 (HDMI receptacle).
  4. Insert an HDMI video sink into P2 (HDMI receptacle) using a standard HDMI cable.
  5. Video output on HDMI sink should be observed.
