AR-200S RS-232C Reference -

3) Commands originating automatically from the AR-200S

Some commands are transmitted automatically from the AR-200S. The two commands CC (card

insertion status output) and %% (completion status output when a card operation takes place)

fall in this category, and use the following procedure.

a. stx + command

COMPUTER AR-200S

a. The AR-200S will automatically transmit the command.

There is no need to return an ACK, etc.

4) Commands accompanied by confirmation

The 4.2.2 Edit command explained in chapter 4 is of this type. To prevent accidental erasure of

data, edit commands are executed after entering Delete mode. Commands use the following

procedure.

a. stx + DM command

COMPUTER AR-200S

b. ack or stx ER command

c. ack or stx ER command

d. stx + Edit command ( same as step “c” )

e. ack or stx ER command

a. Transmit the DM command. The AR-200S will enter Delete mode. Then PLAY/CLIP

indicator and REC indicator will flash alternately.

b. If the DM command is received correctly, an ACK will be returned. If there is a command

error, the ER command will be returned and the AR-200S will automatically exit Delete

mode.

c. If no error has occurred, transmit the command you wish to execute.

d. To confirm, the AR-200S will send back the command that it received in step “c”.

e. If the command is correct, send an ACK. This will cause the command to be executed. Then,

after receiving the command, the AR-200S will automatically exit Delete mode. If the

command is an error, you can send an ER command “ER:1;”. The command will be canceled,

and the AR-200S will exit Delete mode.
