There are 2 parts to ACA functionality:
- Often when we say “ACA” with respect to the 882EA and 882CA we are
referring to the 882's functionality for capturing auxiliary channel
messages (EDID, DDC, HDCP, DPCD, CEC, etc.) as well as the ACA program’s
functionality for logging and displaying the captured messages. In this
case, the generator hardware and the ACA program are working together to
perform ACA functions. The HT-180 hardware also captures these Aux
channel transactions in a similar way.
- The ACA as a computer application (java) is a program that lets you
log and view aux channel transactions. This java application is included
with the 882EA (and 882CA) generators, and is run from the home page of
the web interface. This same program can be used with the HT-180, and is
also available to download separately from our downloads page:
http://www.quantumdata.com/downloads/index.asp.
The HT-180 GUI saves trace files in the same format as the 882CA/882EA
trace files. Because the ACA is available as a separate program, users
of both the 882 and the HT-180 are able to save the captured trace files,
and then view and analyze the transactions later. Neither the 882
generator nor the HT-180 are needed for this later analysis.
If you have the ACA as part of the 882, you can run it from a link on the
882's home page. You can also run the ACA application independently of
the 882.
You can download the current version of the ACA from the downloads
page on our website: http://www.quantumdata.com/downloads/index.asp.
Download the ZIP file, then unzip it into a folder on your hard drive.
To run ACA, double-click QDAca.jar
Notes:
- The other file(s) from the ZIP file must be present in the folder.
- ACA is a Java application, and requires the free Java Runtime Environment,
available from http://www.java.com
- Please also view the readme file, also on the downloads page.
