Creating a test sequence
You can create a test sequence using the command line interface, the generator’s built-in
editor or VGM.

Creating a test sequence using command line

You can develop test sequences either by entering command interactively through a
terminal session or by entering a series of commands in a text file and then send them to
the generator through hyper terminal. When developing long test sequences, the
recommended procedure is to enter commands in a text file, and then send the file to the
generator. This approach enables you to change the test sequence without entering the
entire command script.
Use the following procedure to create a test sequence, save it to the sequence directory,
and then run it using the command line interface.
To create and save a test sequence interactively using the command line interface:
1. Establish a terminal session with the generator.
2. Enter the following commands to create a three-step sequence named MySeq.
SEQN // initializes the sequence edit buffer
SEQB // begins a sequence editing session
STEP 1 // selects a step to be edited
SDLY 5.0 // sets the delay for the current step to five seconds
FMTL 480p59 // loads a format
IMGL SMPTEbar // loads an image
STEP 2 // selects a step to be edited
SDLY 5.0 // sets the delay for the current step to five seconds
FMTL 720p60 // loads a second format (same image)
IMGL Outline1 // loads an image
STEP 3 // selects a step to be edited
SDLY 5.0 // sets the delay for the current step to five seconds
FMTL 1080i29 // loads a third format
IMGL Geom_4 // loads another image
SEQE // ends the sequence editing session
SEQA MySeq // saves the current contents of the sequence editor
To create and save a test sequence from a text file:
1. Using a text editor, open a text file (command file) on your computer and enter the
following commands to create a three-step sequence named MySeq.:
SEQN // initializes the sequence edit buffer
SEQB // begins a sequence editing session
STEP 1 // selects a step to be edited
SDLY 5.0 // sets the delay for the current step to five seconds
FMTL 480p59 // loads a format
