Chapter 3: Built-In Formats
Model 801GC, 801GF & 801GX ¥ Rev. A
Introduction
The charts on the following pages list the generator’s
built-in formats library. These are stored in read only
memory (ROM) along with the generator’s operat-
ing code. They can be used as starting points for
creating your own formats and new ones can be added
to the nonvolatile RAM. A maximum of 300 formats
can be stored in RAM.
The same format library is used for all models in
the 801G series. Some formats are for displays and
graphics systems that may not be compatible with a
specific generator model. If a format has too high of
a pixel rate, a modified version of the format is placed
in RAM with reduced horizontal timing parameters
that bring the pixel clock rate below the limit of the
generator. The horizontal and vertical rates how-
ever are correct. This lets you light-up a display and
verify most of its operation. These modified formats
are created by the memory re-intialization routine.
In other cases the library format may have a video
type or sync type selection that may not be compat-
ible with a specific generator model. Attempting to
load an incompatible format will give you an error
message.
The charts give only a general description of each
format. More detailed information can be obtained
in one of the following ways.
■
You can use the Format test image to display a
detailed list of parameters of any format in
firmware or RAM.
■
You can use the built-in Graphics User Inter-
face to view and edit the contents of any for-
mat. Also you can check, modify, and copy
formats with a terminal or computer connected
to a generator’s communications port.
