Routine Troubleshooting
Use this procedure if:
•
Dome does not respond to commands
•
Dome does not produce video
•
Quality of the video is poor
•
Dome has no lens control.
Read the following CAUTIONS:
CAUTION:
DO NOT use this procedure if the
dome functions but does not pan or tilt
(see page 18).
CAUTION:
If an I/O board is used, use a ground
strap when handling the board.
CAUTION:
When shipping a base having an I/O
board to the manufacturer, place the dust cover
over the spring finger connector to protect it.
CAUTION:
Connector screws on the I/O board
are delicate. DO NOT overtighten them! Use a
2.5mm (0.1") slotted screwdriver. Wider blade
widths can damage connectors.
Procedure
Follow steps until the problem is corrected.
1. Check video on monitor.
No video? Go to step 2.
Contrast or color off?
YES Ship entire dome (base included, if it
contains an I/O board) back to the NSC.
Place dust cover over spring finger
connector on I/O board.
NO Go to step 2.
Video rolls when switching between monitors?
YES Use video controller or switcher to
synchronize video vertical sync phases
of all domes to ac line. For specific
instructions, see installation and service
manual for controller or switcher.
NO Go to step 2.
2. Check ac power and video
connections at J-box.
24Vac absent? Video signal absent?
YES Correct problem at J-box.
NO Go to step 3.
3. Check dome address switches.
Detach dome from base and examine address
switches. Are they set correctly?
YES If dome still doesn’t respond, ship entire
dome (base included, if it contains an I/O
board) to the NSC. If you must repair the
dome, see “Detailed Troubleshooting”,
next.
NO Set correct address and reattach
housing and eyeball assembly.
Steps 4–9 are only for bases with I/O boards!
If the mounting base DOES NOT contain an I/O
board, stop here and ship the housing and eyeball
assembly to the NSC. See “IMPORTANT!” on
page 18 for phone numbers. If mounting base
does contain an I/O board, go to step 4.
