Table 10
Troubleshooting Table.
Fault Symptom
Possible Reason
Check/Do
No connection to camera
No power
Check power supply
Check LEDs on IO Board
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)
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 camera properties for trigger source section 2 – 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 field 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 field 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)
Camera has no light
sensor information
If the camera uses external light sensor then check that the IP
address and port is set correctly. Check if a light sensor error
information is found in EN Setup Properties Status field
(section 10)
An external light
sensor is used and
might be positioned
wrongly
Check that the A-side of the TLS-301 is facing the same
direction as the vehicle license plate
Ensure that the light sensor is exposed to the same light
conditions as the viewed scene
ALC value
Select ALC, adjust ALC target value.
