Computer Control

NOTE: Some commands, sent after a specialty command which includes an AUTOSTOP setting, (PL, MF, MR, etc.), cause the player to execute the new command before the AUTOSTOP is enacted (see Chapter 5, Command Descriptions).

When all the commands in a string have finished executing, the player transmits or returns the "complete" message that is represented by the capital letter R.

The player returns an R after a command has been executed. This response is called the Automatic Status. The Automatic Status signals the computer program to send the next command. If this function is not used, the command processing Time must be taken into consideration before the next command is sent.

If an error occurs, the player returns an error message such as E04. The message indicates an error has occurred as well as the type of error. Error messages are in the form of EXX where XX represents a 2-digit error code.

In some cases, an incorrect command sends the player to Search within a non-recorded area and the player returns an error message. Use the Request Status function to determine the unit’s current status (actual player hardware failures are rare).

Apply one of the following methods to reset the player after an error has occurred:

•?P to determine the Active mode of the player

•?X, ?W, ?M, ?H, ?H ?S to determine the player information, model name, clock time, player region code, the setting of Industrial Player Menu, etc.

•?F, ?T, ?C, or ?R to determine the current Frame, Time, Chapter, Title/Track number, respectively.

•?V, ?D, ?K, ?G, ?Y, or ?Q to determine the disc information, disc type, total Frame number, TOC information, etc.

The status functions are summarized below:
