Raymarine e7 Installation Instructions Manual page 97

Problem
Erratic or unresponsive controls.
Cannot switch between thermal and
visible (VIS / IR) video image .
Noisy image.
Troubleshooting
Possible causes
SeaTalk hs problem.
Control conflict, e.g. caused by multiple
users at different stations.
Problem with the controller.
Camera is not a dual payload model.
VIS / IR cable not connected.
Poor quality or faulty video cable.
Cable is picking up electromagnetic
interference (EMI) from another device.
Possible solutions
Check that the controller and thermal camera are correctly connected to
the SeaTalk hs network. (Note: This may be a direct connection or via a
SeaTalk hs switch.)
Check the status of the SeaTalk hs
Check that SeaTalk hs cables are free from damage.
Ensure that no other controllers are in use at the same time.
Check power / SeaTalk hs cabling to the controller and PoE injector (PoE only
used with optional Joystick Control Unit).
Check other controllers if available. If other controllers are operating this will
eliminate the possibility of a more fundamental camera fault.
Only "dual payload" (dual lens) thermal cameras support VIS / IR switching.
Ensure that the VIS / IR cable is connected from the camera to the
Raymarine system. (The IR-only cable does not support switching).
Ensure that the video cable is no longer than necessary. The longer the
cable is (or the smaller the wire gauge / thickness), the more severe the
losses become. Use only high quality shielded cable suitable for a marine
environment.
• Ensure you are using a high quality shielded cable.
• Ensure proper cable separation, for example do not run data and power
cables in close proximity with each other.
