PAV LAN
35
Appendix
Troubleshooting
 The IP address cannot be set. The LAN status indicator LED is lit red.
 The IP address is all zeros. The LAN status indicator LED is lit red.
 Even when I click Refresh list on the webpage, slave PAVs are not detected.
Inspection Remedy
• Turn the PAV’s POWER switch
off and then back on.
Check that the voltmeter shows
“
LAn
” for a few seconds.
• If this does not appear, set the PAV to LAN remote mode.
(p.9)
• If IP1 to IP4 do not appear, LAN is disabled. Check that LAN
is selected. (p.9)
Inspection Remedy
• Check that the LAN cable is con-
nected to a valid network.
• Connect the LAN cable to a valid network. Wait a moment,
and display the IP address again. (p.11)
In auto IP mode, the IP address is generated within 30 sec-
onds of turning on the POWER switch.
• IF the link LED on the rear panel is not lit green, the LAN
cable is not connected properly.
• Two devices on the network may
be set to the same IP address.
If the PAV is in this condition, an
IP address cannot be assigned.
This may occur when the PAV is
in static (fixed) IP address mode
(p.11) .
Perform either of the following remedies (1 or 2).
Remedy 1:
• Reset LAN from the front panel.
(p.14)
The PAV obtains an address from a DHCP server on the net-
work or generates an address in the 169.254.xxx.xxx subnet.
• If this subnet is different from the address, set an IP address
compatible with the network from the front panel. (p.11)
Remedy 2:
• Remove the LAN device with the same address from the net-
work.
• Turn the front panel POWER switch on and then back on.
After 10 seconds, the PAV assigns a static (fixed) IP address.
Inspection Remedy
• Check that the master unit is con-
nected to the LAN.
• Check that all slave units are set
to RS485.
• Check that all slave units have
unique addresses and that the
data rate (baudrate) is set to 57.6
kbps.
• Connect the master unit to the LAN.
• Set all slave units to RS485.
• Assign unique addresses to all slave units, and set the data
rate (baudrate) to 57.6 kbps.
