A.4. Troubleshooting
This section provides useful information and remedies for common situations where problems
may be encountered.
Problem
Try
No Ethernet 10/100
status LED when
Ethernet is connected
(other LEDs are OK).
Hardware issues:
 Check that the network is working and the unit is powered
on.
 Check that the network (Ethernet) cable is properly
attached to the unit.
 Confirm that the LED on the Ethernet (RJ-45) connector on
the power connection panel of the unit is on.
 Confirm that the network cables are not damaged and
replace if necessary.
IP Address issues:
 Change the default IP address/addresses of the unit.
 From the PC running the web browser, ping the unit IP
address and confirm that it can be reached.
 Confirm that the network settings/firewalls are set
according to the requirements.
How to find out what
IP is being used.
Run the Configurator. It will listen on the network to discover
all active units. See Configuring the Encoder’s Network IP
Settings (page 19).
The IP responds to a
ping on the network
from the workstation
but is not showing in
the Configurator.
Disconnect the encoder Ethernet 10/100 port or turn off the
encoder’s power and then ping the IP again. If the IP responds
there is another device using the IP. Consult with the network
administrator to resolve the conflict.
The encoder IP is
already in use by
another computer
(collision).
Use the encoder HTML setup or Configurator application to
change the encoder IP after connecting to it directly (not
through the system network). See Configuring the Encoder’s
Network IP Settings (page 19).
