Section4 Details of each Command

4.1 Commands Transmitted from the External Device (Computer) to the AR-200S

The following 5 types of command are transmitted from the external device to the AR-200S.

“External” in these explanations refers to the computer. “AR” refers to the AR-200S.

1) Control (execute) commands

These command signals cause the AR-200S 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-200S 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.

Commands valid when in Delete mode

External to AR

CD: Delete Card

CP: Copy Card

FM: Format Card

LS: Recorded Phrase Protect Mode

LW: Recorded Phrase Protect Mode

PC: Copy Phrase

PD: Delete Phrase

PI: Seek and Set Playback Points at the

Locations of Silent Portions

In Delete mode, when a command other than an Edit command is received by the AR-200S, it

will automatically exit Delete mode, and execute that command. If the AR-200S 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-200S parameters from the external device.
