9. Command Reference
This section provides a list of commands available for use with the 980 DP Video Generator.
Since the 980 can be equipped with multiple modules, there is a convention for addressing commands to specific
modules. By default any command you enter will be addressed to the 980 DP Video Generator module in slot 3.
The addressing convention is as follows:
<IN/OUT><Slot><Port>: command_string
Here are some examples of addressing commands. The configuration used in these examples is a 980 DP
Protocol Analyzer module in the first slot (Slot 1) and the 980 DP Video Generator module in the third slot (Slot 3).
Example #1: Load a format (resolution) for the transmitter port (Tx1) on the 980 DP Video Generator module:
OUT30:FMTL SMPTEBar
Example #2: Query the image transmitted:
OUT30:IMGU?
Notes :
1. Text case is not important.
2. Since both Tx ports on the DP Video Generator module always transmit the same signal, you do not have to
include the port number.
