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:

- 6

1 2 ... 8 9 10 11 12 13 14 15 16 17 18 ... 112 113
