Solution
•
Ensure that the AutoDome is powered, and all cables are properly connected.
•
Ensure that the address is properly set.
•
Ensure that the biphase or RS-232 is connected.
•
Ensure that other cameras can be controlled; if not, check the control system.
•
Ensure that the address is set. If an address is set to 0000, it responds to commands
for any address.
•
Ensure that GAIN CONTROL is set to AUTO (ON-43-ENTER).
•
Ensure that Iris level has not changed; if so, adjust the IRIS control on the
keyboard. To permanently adjust, use ON-11-ENTER.
•
Verify proper termination.
•
Unlock commands (OFF-90-ENTER; may require password).
NOTE: Commands automatically lock 30 min after being unlocked.
1. Try resetting factory defaults (ON-40-ENTER).
2. Position camera so the entire view is white (white wall).
3. Enter the White Balance menu (ON-30-ENTER). Move the joystick until one push
W.G. is selected. Wait 10 sec. Press IRIS to return.
4. If this does not work, restore factory defaults (SET-899-ENTER). Note that this
erases all presets and settings.
Verify that a 110 Ω resistor is across the +/– biphase code terminals at the last
•
dome in a daisy chain configuration.
•
Turn on backlight compensation (ON-20-ENTER).
•
Electronic AC power line noise may distort the picture and cause loss of Sync.
If the picture is distorted, try switching to Internal Crystal (OFF-42-ENTER).
If this corrects the picture problems, there may be excessive line noise on the
power supply.
