The serial control ICD commands are presented here for the user’s knowledge. The commands are written and controlled by Z Microsystems and are not intended for the customer to use. Any improper use of the commands may place the panel in an unstable state and may degrade the image quality, thereby voiding the warranty by the user.
Command Structure
The command structure for the majority of the commands for the display follow the follow- ing structure:
Z<space>U<space><command><space><argument>
where...
“command” = the ascii string that represents the command “argument” = the optional argument to the command “space” = ascii character 0x20
The command structure must be succeeded by a carriage return (0x0D).
The controller returns a string of tildes (‘~’) indicating that the command has been ac- cepted and processed. Some of the commands return other information which will be specified on a per command basis.
Unless otherwise specified the command strings examined in this document must be placed in the above structure when being sent to the controller.
The commands will be broken down by the image on which it operates (i.e. the main im- age). There may be overlap between the different images and the commands that work on them.
Main Image—Standard Command Structure
The following commands operate on the main image.
PAA
Description
PAA has the controller perform its auto adjust algorithm. This often helps the main image properly position itself if an uncommon image stream is provided to the display.
