AR-3000 RS-232C Reference -6
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 The DM command is sent, and the AR-3000 enters Delete mode.
2. AR to External 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.
3. External to AR If no error has occurred, transmit the command to be executed.
4. AR to External The command transmitted in step 3 will be re-transmitted for
confirmation.
5. External to AR 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.

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.
