Troubleshooting and diagnosis
L-NET network (refer to the LA NWM video tutorial for software use)
Inspection procedure / Diagnosis
Impossible to connect a controller
to the L-NET network
(controller
not
in “grey 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 or
several controllers with
the same IP address
Set the 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 CAT5e U/FTP cables
into the L-NET connectors on the
controller to connect it to other controllers
in the network chain, a computer or an
Ethernet switch (each of the two
connectors can be equally used as an IN
or LINK connector).
Refer to the
LA NWM video tutorial
for network setup.
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.
Replace all damaged CAT5e U/FTP
cables of the network chain from the
controller to the computer.
7. more than two software
clients are already
connected to the
controller
Disconnect all other software clients.
