IEEE 488 Configuration Settings
Standard Units, Only
1. Ensure IEEE 488 Interface is installed.
2. Turn the ChartScan system's power "OFF."
3. Ensure the COMM SELECT micro-switch (on the
rear-panel DIP switch) is in the "1" (up) position.
This selects IEEE 488.
4. Adjust micro-switches 4 through 8 (for address
setting), see 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.
