2.2 Basic Setting
Description
Set the IP address of the own node.
Ensure that the own node and the external device to be communicated with have the
same class and subnet address.
Set the IP address in the range of class A/B/C.
If IP address is not set, the module operates as if 192.168.3.3 is set.
The setting values of the IP address differ according to the setting values of the
Subnet mask. Take note of the following points to set the IP Address and the Subnet
Mask setting.
• Bits of the host address (parts of the subnet mask that carry 0) of the IP address
are not all set to 0 or 1.
• Bits of the network address (parts of the subnet mask that carry 1) of the IP
address are not all set to 0 or 1.
Set the subnet mask of the own node.
This setting is used to determine how many upper bits among the IP addresses are
used in the network address. The network address is then used to identify a network.
For example, set '255.255.255.0' when the upper 24 bits of an IP address are
assigned to the subnet mask.
The setting values of the IP address differ according to the setting values of the
Subnet mask. Take note of the following points to set the IP Address and the Subnet
Mask setting.
• Bits of the host address (parts of the subnet mask that carry 0) of the IP address
are not all set to 0 or 1.
• Bits of the network address (parts of the subnet mask that carry 1) of the IP
address are not all set to 0 or 1.
Set the IP address of the default gateway (the device which the own node passes
through to access a device of another network).
Set the subnet address of default gateway so that it is the same as the one of the
host station.
