Incoming Inspection
17. Short pins 1 and
9 together on the remote cable.
18. Preset A4 should be restored so that a picture is displayed in tile 4. It may
take several seconds for the display to change.
19. Record Pass or Fail for Activate Preset in the test record.
20. Restore saved presets from the USB flash memory device (if saved before
this procedure).
Test Ground Closure Out.
21. Connect a voltmeter or oscilloscope to monitor pin 5 of the DSUB connector.
22. Verify the voltage is greater than 4.5 V. This indicates the output is not
asserted.
23. Connect a 525/270 color bar signal from DVG1 to the SDI A input.
24. Restore the Factory Preset. (See page 60, Restore the Factory Presets.)
25. On a 15-pin, male DSUB connector, solder wires or strip back insulation to
gain access to pins 2, 5, and 9.
26. Connect the DSUB connector to the ground closure remote connector on
the waveform monitor.
27. Press the CONFIG button to display the CONFIG menu.
28. Select Alarms > SDI Input,thenpresstheSEL button.
29. Usethearrowkeystomovetheselection highlighting to the Ground Closure
column of the SDI Input Missing row, and then press SEL to put an X in
the box. This i nstructs the waveform rasterizer to assert the ground closure if
the input is not present.
30. The voltmeter should read about 4.7 V on pin 9.
31. Remove the input signal from the SDI connector on the rear panel to assert
ground closure.
32. The voltmeter should now read a low voltage, below 0.5 V.
33. 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. The
computer mut have a Web browser insalled.
2. Restore the Factory Preset. (See page 60, Restore the Factory Presets.)
3. Press the CONFIG button to display the Configuration menu.
4. Select Network Settings > IP Confi gure Mode.
5. Verify that the IP ConfigModeissettoManual.
