Section 4 Details of each Command
4.1 Commands Transmitted from the External Device (Computer) to the AR-3000SD
The following 5 types of command are transmitted from the external device to the AR-3000SD.
“External” in these explanations refers to the computer. “AR” refers to the AR-3000SD.
1) Control (execute) commands
These command signals cause the AR-3000SD 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-3000SD enters Delete mode.
2. AR to External
When the command is received correctly, an ack/OK 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/OK 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.
Commands valid when in Delete mode (External to AR)
PD: Delete Phrase
PC: Copy Phrase
FM: Format Card
CD: Delete Card
CP: Copy Card
SP: System Copy
LS: Recorded phrase protect mode
LW: Recorded phrase protect mode
- In Delete mode, when a command other than an Edit command is received by the AR-3000SD,
it will automatically exit Delete mode, and execute that command. If the AR-3000SD 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-3000SD parameters from the external device.
4) Request commands
This command causes the AR-3000SD to output the status of its current settings. When a Request
command is transmitted to the AR-3000SD, the AR-3000SD will transmit the requested contents as
the Setting output command. In this case, an OK will not be returned. However for the AC and AQ
commands, an OK will be output. If the command was not correct, an ER command will be returned.
5) Reply commands
Reply commands are necessary for communication control, for example to notify that a command was
received correctly.
