Set up the computer in the conventional configuration, with power cables, mouse, keyboard, and monitor. Connect the VR8500 network port to the dedicated network card in the computer using the included yellow crossover cable. If your VR8500 is labeled "Adapter Cable Required", the included red adapter cable and metallic CAT5 in-line coupler MUST be connected between the yellow crossover cable and the network port of the VR8500. -
Page 5: Establishing Communication With Pc
Connecting two or more VR8500 units Two or more VR8500 units require a network switch. Connect the first VR8500 to port 1 on the switch. Additional VR8500's can be connected to port 2,3, and 4 on the switch. Connect the computer to highest numbered port with the supplied cable. - Page 6 VR8500 Assign address 192.168.3.10 and subnet mask 255.255.255.0 as shown in the Internet Protocol (TCP/ IP) Properties dialog box. If multiple network cards are installed in the computer the IP address can be adjusted. Other recommended values are 192.168.2.10 and 192.168.4.10, although any Class C or Class D subnet will work.

When the appropriate values are entered, click the "OK" button. The new accelerometer sensitivity factors will take effect immediately. Note: Be sure to check the “Accel power source” box if you want the VR8500 to provide the constant current source to your accel. -
Page 8: System Limits (Shaker Limits And Moving Mass)
VR8500 SYSTEM LIMITS (shaker limits and moving mass): The controller checks the system specifications to determine if the shaker is able to perform the current test. The shaker force, velocity and displacement limit values only need to be entered once when the system is first configured. - Page 9 Return to step 4. If the shaker still does not move, connect the Drive output connector of the VR8500 to an oscilloscope or true RMS voltmeter, set the output voltage level to 0.5 volts (0-to-peak) and verify that you have a 0.5 volt (0-to-peak) amplitude...

Page 10: Sineview Test Set-Up
VR8500 SineVIEW TEST SET-UP: Click the New Test button and select “Sine” to begin defining a new Sine test. This will guide you through the following series of configuration dialog boxes. Default values will be supplied for all parameters. If you are unsure about a parameter, use the default value (click the “Help”... - Page 11 VR8500 Sine Limits - The tolerance and abort limits for the test are entered here. The control tolerance and abort limits apply to the control signal. If monitoring channels are being used, enable the appropriate channels in the Sine Channels dialog box and enter the plus and minus abort limits for the monitor channel.
- Page 12 VR8500 At this point the test definition is complete. Click the "Finish" button to close the dialog box. You will be asked if you want to save the test definition to the hard drive. Click the "Yes" button; enter the desired name and click the "Save"...

Page 13: Randomview Test Set-Up
VR8500 RandomVIEW TEST SET-UP: To run a preset test profile, click on the Test Type button and select “Random”. Next, click the Open Test button and select a profile. Or, to define your own profiles, click the New Test button and select “Random”... - Page 14 VR8500 Random Channels - The control channels are selected here, as well as averaging or extremal channel combination methods. Random Data Storage - The directory into which the data from this test will be stored is selected here. Data can be automatically stored on a regular time interval, at the end of each level (levels are defined using the Schedule dialog box) and at the end of the test.

VR8500 ShockVIEW TEST SET-UP: Click the New Test button and select “Shock” to begin defining a new Shock test. This will guide you through the following series of configuration dialog tabs. Default values will be supplied for all parameters. If you are unsure about a parameter, use the default value (click the “Help” button in the lower right corner of the Settings window for specific Help information). - Page 16 VR8500 Data Storage - The directory into which the data from the test will be stored is selected here. Data can be automatically stored at a regular pulse interval, at the end of each level (levels are defined using the Schedule dialog box) and at the end of the test. All pulses that lie outside of the defined tolerance lines can also be stored.

VR8500 FDRVIEW TEST SET-UP: Click the New Test button and select “Field Data Replicator” to begin defining a new FDR test. This will guide you through the following series of configuration dialog tabs. Default values will be supplied for all parameters. If you are unsure about a parameter, use the default value (click the “Help” button in the lower right corner of the Settings window for specific Help information). - Page 18 VR8500 Filter - The frequency range over which the controller will operate is entered here. Typically one would select control from 0 Hz up to 40% of the sampling rate. If you wish to filter out low frequencies to limit the displacement requirements or filter out high frequencies to avoid shaker resonances, a smaller frequency range can be specified.

Page 19: Automatic Report Generation
VR8500 AUTOMATIC REPORT GENERATION: Reports are generated using mail merge type processing. The program reads in a template file, substitutes data values and graphs in place of keywords, and writes the resulting data to an output file. The template files can be either plain text or Rich Text Format files. Plain text files can have data values but no graphs. - Page 20 VR8500 C:\VibrationVIEW5\Program Files\Templates\DataReplay\Forms. The html file can contain any html element which can be displayed by Internet Explorer. A typical html form file contains a single form with controls for text entry. The text can be automatically inserted into the test report. With a form the data entry can occur during test setup, and the appropriate report run at the end of the test.

VR8500 TIPS & TRICKS: Graphs To copy the data for a graph trace, either double click the graph • trace label and select the data tab and copy, or hold down the Ctrl key and double click on the trace of data. Click “Copy” to copy the numbers to the clipboard, and then paste in another ap- plication such as Excel. - Page 22 VR8500 "Extract profile from data (*.v?d)" Select the saved data file. Automatically save a report by inserting a step at the end of a test schedule to Save Report using the • dropdown arrows. Also, be sure to choose a template from which to create the report Save reporting time by using the Forms feature that is available in the test schedule drop downs.
