DVD-V5000 DVD Player
RS-232 Command Protocol
3.3 Command and Status
During normal operation, when a computer transmits commands to a DVD-
V5000, the player responds with the status message, ‘execution complete’.
Example
COMPUTER DVD-V5000
(1) “Search to Frame 1000” ⇒ (2) Search Execution
⇐ (3) Complete
(4) “Play to Frame 2000” ⇒ (5) Play Execution
⇐ (6) Complete
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-V5000 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.
