6 Appendix B: Troubleshooting and maintenance
Fault Symptom
Possible Reason
Check/Do
No connection to camera
No power
Check power supply
Check LEDs on I/O Board (see next page)
No Ethernet
connection
Check if Ethernet switch has contact with camera (LED on
switch is flashing)
Check LEDs on camera RJ45 connector
Ethernet network
configuration
Check IP Addresses and subnet configuration (see Section 4 of
this manual)
Use net scanning software to map network configuration (e.g.
Softperfect Network scanner or similar)
Firewall/Antivirus
(EN Setup does not detect cameras, but cameras respond to a
“ping”) Disable any firewall and antivirus software.
Camera abnormal
behavior
(Typically indicated by red
cross or question mark on
camera icon in EN Setup)
Conflicting IP
addresses
Correct IP address configuration in cameras
– no duplicate IP
address is allowed in the same subnet
Poor network speed or
bad cabling
Verify cabling consistency with suitable network tester (e.g.
Test-Um model Validator/Fluke model DTX Cable Analyzer)
Camera does not trigger
Trigger source is not
set correctly in
Camera Properties
Check EN Setup camera properties section 2 for trigger
properties
– Trigger – External Trigger Source
Check that the camera can be triggered via the EN Setup video
window
– Eth. Trigger (Ethernet trigger must be enabled in
properties section 2
– Trigger – External Trigger Source)
If system has a VJP-300 then activate trigger push button (S1)
and verify that an image is being grabbed. (TTL must be
enabled in properties section 2
– Trigger – External Trigger
Source)
Trigger Polarity
Switch S3 and/or S5 on J-Panel set to the wrong trigger
polarity. Please refer to VJP-300 section for setting the
switches.
Abnormal daytime image
exposure (too dark or too
bright)
ALC value
Select ALC, adjust ALC target value.
Dark night images
Connection to external
flash not correct
Check that wiring is in accordance with Appendix A and the
flash manual. Check by pushing switch S1 that the flash fires
(located next to input connector X4 on IO Board)
Strobe polarity is not
set correctly
Set strobe polarity in camera properties
4
– Light, Flash
Polarity to Normally Low
Strobe is not enabled
Set strobe enable correctly in camera properties
4
– Light,
Flash Auto/Manual
(Auto = always enabled, Min(A-Side, B-
Side) enables/disables EN Strobe = based on Light Sensor
reading)
