Incoming Inspection
Test Ground Clo
sure Out.
11. Connect the voltmeter to pins 2 and 9 of the DSUB connector.
12. Verify the voltage is about 4.7 V. This indicates the output is not asserted.
13. Press CONFIG to display the CONFIG menu.
14. Select ALARMS > SDI Input,thenpresstheSEL button.
15. Use the arrow keys to get to the top-right corner of the Input error check box,
and then press SEL to put an X in the box for the Ground Closure column and
the SDI Input Missing row. This instructs the waveform rasterizer to assert
the ground closure if the input is not present.
16. The voltmeter should read about 4.7 V on pin 9.
17. Remove the input signal from the SDI conne
ctor on the rear panel to assert
ground closure.
18. The voltmeter should now read a low voltage, below 0.5 V.
19. Record Pass or Fail for Ground Closure in the test record.
Ethernet Test
1. Connect an Ethernet cable from the rear of the unit to a computer with a Web
browser.
2. Press FACTORY to restore the factory preset.
3. Press the CONFIG button to display the Configuration menu.
4. Select Network Settings > IP Configure Mode.
5. Verify the IP ConfigModeissettoManual.
6. Select Network Settings > IP Address.
7. Use the left/right arrow keys to move the highlight to each box in the address.
Use the up/down arrow keys to change the number in each box as required.
Set the IP Address t o be compatible with the computer.
8. To accept your changes, move the highlight to the Accept box and press SEL.
9. From the computer, enter the IP address of the waveform rasterizer into the
Web browser address line (for example, http://192.182.256.23).
10. You s hould see a Web page that lists several o ptions for accessing the
waveform rasterizer from the PC. If this happens, then the Ethernet function
is working.
11. Record Pass or Fail for Ethernet in the test record.
NOTE. While in Simultaneous Input mode, certain displays can be displayed
either on the left or on the right, but not both at the same time.
