Configuring generator to not respond to CEC messages
The 882 can be configured to not respond to CEC messages from a device. When the 882
is configured to not respond to CEC messages, it acknowledges (ACKs) messages, but
does not send responses to commands/queries.
To disable responses to CEC messages:
1. Enter the following command to disable responses on the HDMI connector:
CEC1:RSPG 0
//disables responses on the HDMI Tx output 1 port
CEC3:RSPG 0
//disables responses on the HDMI Rx ports
To enable responses to CEC messages:
1. Enter the following command to enable responses on the HDMI connector:
CEC1:RSPG 1
//enables responses on the HDMI Tx output 1 port
CEC3:RSPG 1
//enables responses on the HDMI Rx ports
Querying the CEC message log
You can view the CEC message log from a file or query the contents of the log through the
command line. The preferred way to view the CEC messages is to use the Auxiliary
Channel Analyzer (ACA) which is covered in the next subsection. The message log is a
circular queue with twelve messages (frames). You can view any message in the queue
through a command line query using an indexing parameter. You can also clear the log
through the command line. Each CEC message in the queue contains the following
information:
•
Source logical address
•
Destination logical address
•
Opcode
•
Parameters (if any)
•
Parameter list length
The procedures below show how to view the CEC log either as a file or through the
command line with queries.
To view CEC messages through a file:
1. Connect the source generator to the PC using an Ethernet patch cable or cross over
cable between the Ethernet ports on the PC and the generator
environment" on page 142.
