Auxiliary Channel Analyzer – Passive and Emulation Monitoring
8.3
The Aux Channel Analyzer test monitors the CEC and DDC channel transactions and hot plug events. You can
monitor the events while emulating either an HDMI source or sink device or you can passively monitor the
transactions. You can also monitor while emulating an HDMI source or sink device and passively monitoring
the other side. For example you can configure the 780/780AH to emulate an HDMI source device and monitor
the upstream side and then you can passively monitor on the downstream side (i.e. on the source side of a
repeater and the HDMI sink [HDTV]). This subsection describes the procedures for passively monitoring and
monitoring while emulating.
The features and functions described in this section are included only if you have purchased the
Auxiliary Channel Analyzer – Passive Monitoring option which requires a new hardware module with 4
additional HDMI ports.
You can view the details of each transaction and save the traces for viewing on the external ACA application
available from the Quantum Data website.

system.
8.3.2 Procedures for Passive Monitoring the Downstream Devices while Emulating an HDMI Source
Device with the Auxiliary Channel Analyzer on HDMI Devices
This subsection provides procedures for ACA passive and emulation monitoring of HDMI devices.
Note: You will have to obtain a license key for the ACA passive monitoring option to use the feature.
1. Connect the HDMI system devices to the 780/780AH as shown in the diagram above and described as
follows:
a. The 780/780AH HDMI OUT connector is connected to the HDMI repeater device input connector.
b. The HDMI repeater device output is connected to the 780/780AH Downstream Link IN connector.
c. The HDMI sink device (e.g. HDTV) is connected to the 780/780AH Downstream Link OUT
connector.
2. From the main screen (shown below) touch select the Aux Channel Analyzer activation button.
