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<PIP#><space><command><space><argument>
where...
“PIP#” = the picture-in-picture (PIP) card on which the command
should act. The main image is PIP number “0”
“command” = the ascii string that represents the command
“argument” = the optional argument to the command
“space” = ascii character 0x32
The command structure must be succeeded by a carriage return (0x13).
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
specifi ed on a per command basis.
Unless otherwise specifi ed 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, either the main,
RGB, or NTSC image. There may be overlap between the different images and the com-
mands that work on them.
Main Image—Standard Command Structure
The following commands operate on PIP number “0” otherwise known as the main image.
