Serial Command Syntax
Serial commands to the PD7170 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 PD7170 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 Commands The 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]
