Issue
Possible causes
Inspection procedure / Diagnosis
Impossible to connect a controller
to the L-NET network
(controller not in “blue screen”)
1. offline mode selected on
LA NWM
Select the online mode on LA NWM.
2. scanning range not
containing the controller IP
address
Include the controller IP address in the
scanning range on LA NWM.
3. wrong IP address
Setthe computer IP address and subnet
mask as well as the controller IP address
as indicated in the LA NWM video
tutorial.
4. L-NET cable not plugged
or plugged into the wrong
L-NET connector
Plug and secure a CAT5e U/FTP cable into
the L-NET IN connector on the controller
and the network connector on the device
preceding the controller in the network
chain (computer, L-NET OUT connector on
another controller, or Ethernet switch).
Do the same for each cable of the network
chain from the controller to the computer.
5. L-NET cable incorrectly
plugged
Unplug the CAT5e U/FTP cable and plug it
again on both sides. Do the same for each
cable of the network chain from the
controller to the computer.
6. L-NET cable of wrong
model
Use straight-through Ethernet cables of
CAT5e U/FTP category (or higher) and of
100 m/328 ft maximum length.
If an Ethernet switch is used and the auto
MDI/MDIX functionality is not available on
it, use a crossover cable between the
switch and each controller.
7. L-NET cable damaged
Replace all damaged CAT5e U/FTP cables of
the network chain from the controller to
the computer.
8. another software client is
already connected to the
controller
Disconnect the software client.

Restart the controller.
