Problems with the direct connection to a gigabit network device
Problem Solution
When a device is con-
nected directly to the
KM1 Communication
module using a gigabit
network adapter, no
network connection is
established.
Note
Not all network interface cards support 10
MBits/s half-duplex communication.
Î Alternative A: Interconnect a 100 MBits switch
between the two devices.
Î Alternative B: Set the network connection settings
of your computer to 10 MBits/s half-duplex.
User password not available
Problem Solution
The user password is
not available. When the user password is not available, the KM1
Communication module has to be reset to its factory
settings in order to regain access to the web interface.
Note
When the KM1 Communication module is
reset to its factory settings, the configuration
will be erased.
The KM1 Communication module is not found by the
DeviceDiscoveryTool
Problem Solution
The KM1
Communication module
is not found by the
DeviceDiscoveryTool. Check the following points in order to find and elimi-
nate the error.
Î Check if the power supply to the KM1 Communi-
cation module is established.
Î Check if the network cable is properly connected
at both ends!
Î Check if the firewall software of the computer in-
hibits the connection to the KM1 Communication
module.
Î Switch off the firewall software and use the De-
viceDiscoveryTool to find the KM1 Communica-
tion module.
Î When the KM1 Communication module has been
found, the firewall software has to be reconfigured.
Î Activate the firewall software!
Î Check if the current Java software is installed.
If no or an old Java version is installed, an error message
appears.
In order to eliminate the error, the current Java soft-
ware has to be installed from http://java.com.
Î Check if an IP address is assigned to the KM1
Communication module.
An IP address has to be assigned to the KM1 Commu-
nication module by a router or a directly connected
PC. This process may take several minutes.
Computers with a Windows operating system indicate
an IP assignment in progress by displaying a symbol on
the task bar. The symbol consists of two computers or-
bited by a yellow ball.
Î Check if an IP address is automatically assigned
to the computer upon a direct connection to the
KM1 Communication module.
