Serial Command
Syntax
Serial commands to the LS-7 take the following form:
• Commands are in ASCII format.
• Spaces and tabs can be used to improve readability and are ignored by the projector.
• All commands must end with a carriage return (ASCII hex 0D) to signify that the
projector can now read and execute the command.
• Commands are not case-sensitive.
The LS-7 supports two types of commands: key commands and operation commands.
Key commands mimic pressing a button on the remote control. Operation commands tell
the projector exactly what to do.
All commands start with 2 letters:
ky for key commands.
op for operations commands.
Key CommandsThe syntax for key commands is simple:
ky <keyname>[CR]
Some key command examples:
ky menu[CR] Bring up or cancel menu display.
ky mem.sw[CR] Switch to next user memory.
ky asp.16.9[CR] Apply 16:9 aspect ratio.
The response from the projector for key commands will be the same command in
UPPERCASE.
Input: ky mem.sw[CR]
Response: KY MEM.SW [CR]
