6.Verify Communications With the Communications Configuration File dialog box still open, select instrument 01 on the Instruments on Network list and click the Verify button. The message Connection Successful! is returned for successful communications between the instrument and host computer. If you receive an error message, refer to "Error and Status Messages" in Appendix J. Click OK in the message box and then the Close button in the Communications Configuration File dialog box to return to the Main Window.

7.Configure Icon Note the Icon Bar in the Main Window. If the Icon Bar shows instrument 01, complete Delete Instrument Icon below. If it does not show instrument 01, complete Create Instrument Icon below.

Delete Instrument Icon Select Instrument 01 in the Icon Bar and then select Delete Instrument Icon from the Setup menu. Click Yes in the warning message. Complete Create Instrument Icon below. This sequence causes NetDAQ Logger to reset the current setup for Instrument 01 to default settings.

Create Instrument Icon Select the Create Instrument Icon from the Setup menu. Select instrument 01 on the Available Instruments List. Click OK.

8.Select Reading Rate and Trigger Out Select Setup Instrument Configuration to open the Instrument Configuration dialog box. Select Reading Rate = Slow, and check the Trigger Out box. Click OK to return to the Main Window.

9.Connect DIGITAL I/O Test Leads Remove the 10-position DIGITAL I/O connector from the instrument rear panel or from the connector kit supplied

with the instrument. Connect a test lead to each DIO line 0 to 7, plus a test lead to the Σ (Totalizer) input and the common GND line. Reinstall the DIGITAL I/O connector. (See "Digital I/O Connections" in Chapter 2 of this manual)

10.Connect ALARM/TRIGGER I/O Test Leads Remove the 8-position ALARM/TRIGGER I/O connector from the instrument rear panel. Connect a test lead to each line, MA (Master Alarm), TO (Trigger Output), TI (Trigger Input), plus a test lead to the common GND line. (See "Alarm/Trigger I/O Connections" in Chapter 2 of this manual.)
