Section4 Details of each Command

4.1 Commands Transmitted from the External Device (Computer) to the AR-3000

The following 5 types of command are transmitted from the external device to the AR-3000.
"External" in these explanations refers to the computer. "AR" refers to the AR-3000.
1) Control (execute) commands
These command signals cause the AR-3000 to operate; e.g., playback or record.
The player functions use mostly these commands.
2) Editing commands
To prevent accidental erasure of data, edit commands are executed after entering Delete mode.
Commands are executed using the following procedure.
1. External to AR
2. AR to External
3. External to AR
4. AR to External
5. External to AR
Commands valid when in Delete mode

CD : Delete Card
CO : Convert Card
LS : Recorded phrase protect mode
SP : System copy
PD : Delete Phrase
PT : Delete the silent portions (Truncate)
PV : Divide Phrase

In Delete mode, when a command other than an Edit command is received by the AR-3000, it
will automatically exit Delete mode, and execute that command. If the AR-3000 receives an
Edit command when not in Delete mode, it will transmit an ER command, and ignore the Edit
command that was received.
The DM command is sent, and the AR-3000 enters Delete mode.
When the command is received correctly, an ACK is returned.
If the command is not correct, an error code is returned, and Delete
mode is automatically exited.
* When no command is received for two minutes, the Delete mode is
automatically exited.
If no error has occurred, transmit the command to be executed.
The command transmitted in step 3 will be re-transmitted for
confirmation.
If the command is correct, transmit an ACK command.
The command will be executed, and Delete mode will be exited
automatically. If the command is an error, transmit an ER command
"ER:1;". Delete mode will be exited automatically.
