60 Chapter 12 CEC Interactive Troubleshooting Environment (ITE)
Overview
This chapter provides procedures for testing HDMI source and sink devices for CEC
functionality using the Interactive Troubleshooting Environment (ITE). When testing
HDMI-CEC source devices the generator (analyzer) will emulate a CEC sink device such
as an HDTV. When testing HDMI-CEC sink devices, the 882 generator will emulate a CEC
source device such as a set top box (STB) unless you instruct it not to.
Note: The CEC ITE is an option available on generators with release 2.2.2 or higher. You
must have the ITE option on your generator to use the ITE features. To determine if your
generator has the the ITE option installed, view the GenStats image and check the
information under Video Board - Options. Refer to “Viewing generator configuration
information” on page 117.
The CEC ITE provides a set of commands to accomplish the following:
• Configure an HDMI port on the 882C(A) to emulate an HDMI source of sink
• Send and query messages on the CEC bus
• Query messages on the CEC bus
• Monitor the CEC bus for timing errors
