In addition to using the LS-10i remote control unit, there are three methods of controlling
the projector externally:
• Using a serial (RS-232) link to send ASCII commands and receive responses to those
commands.
• Using discrete infrared (IR) codes to program a third-party remote control unit.
• Using an HDMI connection to send Consumer Electronics Control (CEC) commands
from a BD player or other source component that supports CEC.
The following sections describe these methods.
6.1
Serial Communications The LS-10i uses a simple text-based control protocol to take requests from control
devices and to provide responses to such devices. This section describes how to send
control messages over a serial link between the LS-10i and an automation/control system
or a PC running terminal emulation software.
RS-232 Connection and
Port Configuration To interface the LS-10i 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 3-13.
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
Table 6-2 and press <Enter>. For example, to change the aspect ratio to Letterbox,
type op aspect = 1<Enter>.
Serial Command Syntax Serial commands to the LS-10i 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-10i 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.
