Quantum Data 801GC, 801GF, 801GX manual Built-In Formats

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-upa 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.
