During normal operation, when a computer transmits commands to a DVD- V7400, the player responds with the status message, ‘execution complete’.

Example

NOTE: The length of a command string is limited to 32 characters. Please refer to COMMAND STRUCTURE for additional information.

When using a computer to control the DVD-V7400 player, follow the command protocols listed below:

ASCII characters are used for actual commands and status response

Command mnemonic is expressed as two (2) ASCII characters

Uppercase letters are recommended; however, usually there are no distinctions between the uppercase and lowercase letters

Some commands require an argument (e.g. Chapter number or speed)

Use a command as the terminator of an argument

The player executes a command as soon as the carriage return <CR> is received. The <CR> acts as the command line terminator.

Example

CH<CR>

:

Set Chapter for address mode

10SE<CR>

:

Search to Chapter 10

The player has a command buffer, which stores a command string of up to 32 characters in length.

Example

10SE 20PL<CR> : Search to Chapter 10 then play to 20

The command string enters the buffer with the first character and continues sequentially from left to right. When the <CR> is entered, the commands are executed sequentially beginning with the first command in the buffer. In the example above, the first command is 10SE.

NOTE: The player ignores codes in the command string such as <SPACE> or <LF> (line feed) which have no affect on the player.
