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 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]
