Creating Test Sequences

Overview

In a production environment, where you might need to test several combinations of format

and images, a test sequence can be used to automate the process of selecting formats

and images.

A test sequence consists of steps. Each step specifies the format and image to display,

and the duration of the step.

You can create multiple test sequences, and store them in the non-volatile memory of the

generator. About 1500 steps, from all sequence files, can be stored.
