Graphics Display

How the graphics display interfaces with the processor board.
The attachment shows a switchpanel with graphics display panel for a split pocket washer extractor. If the display is similar on your machine this data applies.

Graphics display and machine software (installed in the processor board) need to be "in sync". For Mark 6 machines and later if the display firmware and the machine firmware are not "in sync" then the machine will prompt to download the appropriate data to the display on power up. This can happen if you update the machine software or change language in configure. Pressing the "level button" will initiate the download. Once the download is finished the machine will automatically proceed to the select formula screen.

All the text data, animation, and color objects are stored in the graphics display flash memory. The machine software uses "hooks" to call these items to display. If the display data is not "in sync" with the machine software then you may see "garbage" on the screen making it impossible to diagnose. All the display data is embedded in the machine software eprom. The software checks the display version on power up and forces a download if the display and software are incompatible.
