RS-232 Connection

and Port Configuration

To interface the VideoWall/CineWall 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 3-6.

2. Press MENU on the remote control and enter the Installer Menu passcode.

3. Select Advanced Options from the Main Menu.

4. Select Serial Port Settings from the Advanced Options menu.

5. Note the Baud Rate setting; change it if desired.

6. Start a terminal session on your PC using a terminal-emulation program, such as

HyperTerminal.

7. Configure the RS-232 controller or PC serial port as follows: no parity, 8 data bits, 1

stop bit and no flow control. Set the baud rate to match that of the VideoWall/CineWall

RS-232 port (see Step

5).

8. To test your serial connection, type ky 00 menu and press <Enter>. If the Main

Menu appears on-screen, the connection is active and working correctly. The

VideoWall/CineWall also responds with ACK in the terminal session window.

How to Form

Commands

Here are some basic rules for composing serial commands:

• RS232 commands consist of a string of ASCII characters.

• All numeric values are decimal; you do not need to use hex or binary digits in the

commands.

• Spaces or tabs may be used in the commands to separate the parts and make them

easier for humans to read. This “white space” is ignored by the command reader in the

VideoWall/CineWall.

• You cannot use commas, slashes, or other punctuation as separators. Periods have a

special purpose in commands.

• Commands are not case sensitive, so you can use upper and lower case letters as you

wish, EXCEPT the first two letters of every command must be both upper or both lower

case. After that, it doesn’t matter.

• When a command requires a response, wait for the response before sending another

command to another display.

• All commands must end with a carriage return character, shown as <code>[CR] in the

rest of this document. Depending on your serial communications program, commands

may automatically be ended with a <code>[CR]. If you are uncertain whether your

application automatically does this, send a test command such as ky 00 menu

without a <code>[CR]. If the menu displays on screen, you will not need to insert a

<code>[CR]. If nothing happens, you will need to add a <code>[CR] at the end of each

command.
