External Control

6. External Control

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.

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.

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 6-1or Table 6-2and press <Enter>. For example, to change the aspect ratio to Letterbox, type op aspect = 1<Enter>.

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.
