Section 4 Details of each Command
4.1 Commands Transmitted from the External Device (Computer) to the AR-3000R
The following 5 types of command are transmitted from the external device to the AR-3000R.
“External” in these explanations refers to the computer. “AR” refers to the AR-3000R.
1) Control (execute) commands
These command signals cause the AR-3000R 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-3000R 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
“stxER:1;”. Delete mode will be exited automatically. Commands valid when in Delete mode

In Delete mode, when a command other than an Edit command is received by the AR-3000R, it will
automatically exit Delete mode, and execute that command. If the AR-3000R receives an Edit
command when not in Delete mode, it will transmit an ER command, and ignore the Edit command
that was received.
3) Setting commands
These commands are used to set AR-3000R parameters from the external device.
