AR-200S RS-232C Reference -

2.2 Handshaking

If the AR-200S's processing speed is slower than the speed at which data is transmitted from the

computer, measures must be taken to avoid data loss. Conversely, data loss will also occur if data

is transmitted from the AR-200S faster than the computer can process it.

For these reasons, the AR-200S uses “Xon/Xoff” handshaking.

The external computer can control transmission from the AR-200S in the same way.

The ASCII code signal name for Xon is DC1, which is 11H.

The ASCII code signal name for Xoff is DC3, which is 13H.

2.3 Setup Procedure

Here is the procedure for setting up the external computer and the AR-200S.

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-200S and the computer

3) Computer settings

Set the communication parameters. Refer to “2.5 Computer settings.”

4) AR-200S settings

Set the communication parameters. Refer to “2.6 AR-200S settings.”

5) Operate the AR-200S

Transmit data between the external computer and the AR-200S.

2.4 Connections with the Computer

1) Turn off the power of the AR-200S 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-200S. Refer to “2.1.1 Connector and

Cable” for the appropriate cable to use.

2.5 Computer Settings

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.
