Steps for RS-232/422 Configuration
Standard Units, Only
1. Turn the ChartScan system's power "OFF."
2. Ensure the COMM SELECT micro-switch (on the
rear-panel DIP switch) is in the "0" (down)
position.
3. Adjust micro-switches 2 through 9 (for parameter
preferences), according to the following table for
standard units.
Note: Early production ChartScan units do not have a Calibration Enable/Disable Pushbutton. If you have an
early production unit, refer to the right-hand DIP switch illustration, above.

It is recommended that you do not exceed 9600 Baud unless you have firmware version 1.3 or greater. The firmware version can be read in
ChartView's title bar.
3
At 9600 and 19200 Baud Rates, Hardware Handshake should be set to "Hardware Handshake Only" (1, 0). We recommend that you do not
exceed 9600 Baud unless you have firmware version 1.3 or greater. The firmware version can be read in ChartView's title bar.
