3. Query the location of the log file:
CECX:LOGP?
The generator returns the path of the log file.
/card0/Library/CEC/Log
Note: By default the CEC log is on the PCCard. Therefore it is important to ensure that
there is a PCcard installed on the generator at all times.
4. Assign a CEC device to a connector:
CEC1:CECL CECDEV03 //assigns CECDEV03 to HDMI Tx Output 1
CEC1:CECU
Here is a second example:
CEC3:CECL CECDEV00 //assigns CECDev00 to HDMI Rx Output 1 and 2
CEC3:CECU
5. Verify the configuration by querying the device parameters of HDMI Tx 1:
CEC1:LA?
//queries logical address of device assigned to HDMI TX1
CEC1:PT?
//queries product (device) type assigned to HDMI TX1
CEC1:OSDN? //queries OSDN of device assigned to HDMI TX1
CEC1:VID?
//queries vendor ID of device assigned to HDMI TX1
Now query the device assigned to the Rx outputs:
CEC3:LA?
//queries logical address of device assigned to HDMI RX1/2
CEC3:PT?
//queries product (device) type assigned to HDMI RX1/2
CEC3:OSDN? //queries OSDN of device assigned to HDMI RX1/2
CEC3:VID?
//queries vendor ID of device assigned to HDMI RX1/2
To create a CEC device descriptor file:
1. Locate the file path for stored configurations:
CECX:CECP?
/card0/Library/CECData/
Change the path if necessary:
CECX:CECP /tffs0/Library/CECData/
2. Create a custom instance of a CEC device for CEC1 using the following commands:
CEC1:CECN <name> //e.g. myTV1
CEC1:CECB
3. Configure the custom CEC device parameters using the following commands:
CEC1:PA 0 0 0 0
//configures (uses) the assigned device
//configures (uses) the assigned device
//begins the CEC editing session
//configures the device physical address
