Appendix A: Checking Power
and Data for Domes Using the
Base without I/O Board
Check LEDs to verify that power and data are
reaching the dome (Figure 39).
IMPORTANT! To view the LEDs, you will need to
detach the dome from its base. To prevent damage
to the dome, hold the dome by its housing, not its
eyeball assembly.
a. If the power LED (CR33) on the I/O board
glows green, then ac power is connected.
b. Green CR2, red (CR3), and yellow (CR4)
LEDs surround the video connection and are
visible through opening. Check that the
following communication protocols are properly
wired by observing these LEDs.
