Sending commands interactively
This section describes how to send commands through an interactive command line
interface session. The 882 parses command lines one at a time. Command lines must be
terminated with a carriage return (<cr>). The 882 immediately echoes each character as it
is received and places it in a command line buffer. Commands are not case sensitive.
When sending multiple commands at once, separate each command with a semi-colon.
For example, to load the 480p59 format with the SMTPEbar image, send the following
commands:
FMTL 480p59
IMGL SMPTEbar
ALLU
Common commands
• To apply an image and format to the 882 hardware, enter:
ALLU
• To display the name of the format currently in the format buffer, enter:
FMTL?
• To load a format, enter:
FMTL format_name
• To apply the format to the 882 hardware, enter:
FMTU
• To load an image, enter:
IMGL image_name
• To apply the image to the 882 hardware, enter:
IMGU
Sending command files (serial interface only)
When developing more complex, custom test sequences or formats, it is easiest to enter
commands in a text file, and then send the file to the 882. This approach allows you to
modify the file without entering the entire command script.
Note: Sending command text files can be performed via the serial interface only.
To send a text file to the 882:
1. Using a text editor, enter commands into a text file, and save the text file using a *.txt
extension.
