When network communications are not functioning, the information will stop after the following:
PING 192.168.0.10 (192.168.0.10): 56 data bytes
If the display appears as shown above, check the following items:
• Is the network cable securely connected to the network connector on the unit?
• Is the network cable securely connected to the Hub/Switch?
• Is the network cable securely connected to the development PC?
• Do the network settings of the development PC match those of the unit?
After checking the above items, start the ping command from the development PC. Then check
the indicator next to the network connector on the rear of the unit.
• When the indicator flashes orange:
The communications are functioning properly.
• When the indicator is not turned on:
The communications are not functioning properly. This may be due to disconnected
cables, damaged connections or a unit malfunction.
The unit cannot be accessed, even though five minutes have elapsed since it was
turned on.
t
Check that the power indicator lights up in green.
If the power indicator is lit green
there may be a problem with the network cable or the connected Hub/Switch. Change the
network cable or Hub/Switch, or contact your network administrator for assistance.
Wireless LAN communications are not working properly.
t
High-frequency noise from the controller may be affecting network communications. Try moving
the controller away from the unit's aerial. Also try adjusting the position of the aerial or moving
the unit to a different location.
