Appendix B. Calibration and Testing with PanaView
B.5.3 Testing XGM868i Hardware
Using PanaView, you can check crucial elements of the XGM868i hardware: the EPROM, the NVR, the RAM, FIFO,
and the DAC. You can also:
• program and test optional cards
• read site checksums and calibration values
• test and set the contrast for the LCD
• set the number of channels (either 1 or 2), and
• reinitialize the XGM868i to its default values.
IMPORTANT: Contact GE if the XGM868i fails any of the tests covered below.

To test the EPROM from the Calibration/Test menu:
1. From the left pane of the Calibration/Test window, double-click on Hardware Test.
2. In the center pane, double-click on EPROM TEST.
3. The right pane displays the EPROM Sum Value. Click [Next Item] or [Exit Page] to return to the Hardware Test
option, and [Exit Page] again to return to the main Calibration/Test menu.
B.5.3b NVR Test
1. From the left pane of the Calibration/Test window, double-click on Hardware Test.
Note: If you are in the Hardware Test option, skip to step 2.
2. In the center pane, double-click on NVR TEST.
3. A message in the right pane cautions that the test will take several minutes, and that interrupting the test may
corrupt the memory. Click [Next Item] to continue the test.
