2.3 Setup Procedure
Here is the procedure for setting up the external computer and the AR-3000.
1) Connections with the computer
Use an RS-232C cable to connect the two devices. Refer to “2.4 Connections with the computer.”
2) Turn on the power for the AR-3000 and the computer
3) Computer settings
Set the communication parameters. Refer to “2.5 Computer settings.”
4) AR-3000 settings
Set the communication parameters. Refer to “2.6 AR-3000 settings.”
5) Operate the AR-3000
Transmit data between the external computer and the AR-3000.
2.4 Connections with the Computer
1) Turn off the power of the AR-3000 and the computer.
2) Use the appropriate cable to connect the RS-232C -compatible connector of the computer to the
RS-232C connector located on the rear panel of the AR-3000. Refer to “2.1.1 Connector and
Cable” for the appropriate cable to use.
2.5 Computer Settings
1) Communication parameters for the computer
Communication method start - stop system (asynchronous) full duplex
Baud rate 4800 / 9600 / 19200 BPS
38400 BPS (for compatibility with legacy models : AR-2000 / AR-1)
Parity none
Data length 8 bits
Stop bit 1 bit

If you are using MS-DOS, the above settings can be made using the “SPEED” and “SWITCH”
commands. For details on these settings, refer to your MS-DOS owner's manual.
2.6 AR-3000 Settings
When using the AR-3000 via RS-232C, the baud rate must be specified.
Also, in order for it to be controlled via RS-232C, the AR-3000 must not be in the Mode menu
(the MODE indicator must not be lit).
2.6.1 Baud Rate
If the AR-3000's power is turned on when a card is not inserted, the baud rate will default to 9600
bps. If a card is then inserted, the settings will change to the settings which are contained in the
card. However this will occur only for the first-inserted card, and subsequently inserted cards will
be ignored. If you wish to modify the baud rate during operation, use the following procedure on the
AR-3000 to change it.
