Table A-1 Troubleshooting Solutions - Honeywell HNVE1 Reference Manual

Troubleshooting
Symptom
There is no power.
The encoder does not start
up normally after turning on
the power.
The STATUS indicator is
blinking (BLINKING
TEMPERATURE WARNING).
The STATUS indicator
continues to blink after
turning off the power and
leaving the unit for a while.
Network Troubles
The STATUS indicator on the
front panel does not light.
The encoder and the
decoder are not
communicating.
It is impossible to access the
setting pages though
pictures can be displayed.

Table A-1 Troubleshooting Solutions
Possible Cause
• The power cord may not be
connected correctly.
• The power plug may not be firmly
plugged into an outlet.
• An IP address may not have been
correctly assigned from the DHCP
server.
• The temperature inside the
encoder may be beyond the
specified temperature.
• The ventilation openings or the
cooling fan slots could be blocked.
The cooling fan may be damaged.
• The ethernet cable may not be
connected to the Ethernet port
(100BASE-TX).
• The correct cable may not be
used.
• The pins inside the connector may
not be connecting or may be
shorting out.
• The cable length per segment may
be longer than the recommended
cable length.
There could be a problem with the
subnet masks.
• The default gate is incorrectly set.
It is necessary to correctly set the
default gateway to access from
different networks (subnets).
• The gateway address is incorrect.
It should be assigned based on
the IP address of the encoder.
Possible Solution
Firmly insert the power plug firmly into
the outlet.
• Confirm that the DHCP server is
running correctly.
• Remove anything from around the
ventilation openings and cooling
fan slots.
Contact your dealer.
• Firmly insert the cable until you
hear a click.
• Use the straight cable when
connecting the unit to a switching
hub or router.
Use the cross cable when
cascading two switching hubs.
When using a switching hub with
the cascading port, refer to the
operating instructions of the
switching hub.
• Check the pins.
• Use network cables that are
appropriate for the transmission
speed and that are shorter than
100 m.
• If the encoder and decoder are in
the same network, then they
should have the same subnet
mask.
• If the encoder and decoder are in
different networks, then the should
not have the same subnet mask.
• Refer to the network administrator
for the default gateway address
and confirm that the settings on
the NETWORK page of the
decoder have been set correctly.
• Refer to the network administrator
and perform the settings.
