To interface the LS-3/LS-5 with a home theater automation/control system or a PC 
running terminal emulation software:
1. Connect it to your control system or PC as shown in Figure 3-12
2. Start a terminal session on your PC using a terminal-emulation program, such as 
HyperTerminal. 
3. Configure the RS-232 controller or PC serial port as follows: 38400 bps, no parity, 8 
data bits, 1 stop bit and no flow control. 
4. Type
 ky or op followed by a command from among those listed in Table 6-1 or

Serial Command 
Syntax
Serial commands to the LS-3/LS-5 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-3/LS-5 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]
