When using a computer to control the DVD-V7200 player, follow the command
protocols listed below:
•
ASCII character codes are used for the 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 use of uppercase or lowercase letters
•
Some commands require an argument, (e.g. chapter number or speed)
•
Use a command as the terminator of the argument
The player executes a command as soon as the carriage return is received.

Example
CH : Set chapter for address mode
10SE : 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 : Search to chapter 10 then play to 20
The command string enters into the buffer with the left character and continues
sequentially from left to right. When the
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 or
(line feed) which do not affect the player’s operation.
