(2) Default router IP address
Set the IP address of the router (default router) when the E71 communicates with the connected devices on other
Ethernet networks via a router other than the one specified in the router information. Set the value that satisfies
the following conditions.
• Condition 1: The IP address class is any of A, B, and C.
• Condition 2: The subnet address of the default router is the same as that of the E71 on the own station.
• Condition 3: The host address bits are not all "0" or all "1".
If the corresponding subnet address does not exist in the router information when the connection is opened or data
communications are performed, communications are performed via the default router.
(3) Router information
(a) Subnet address
Set the network address
connected devices on other Ethernet networks via a router other than the default router. Set the value that

• Condition 1: The IP address class is any of A, B, and C.
• Condition 2: The host address bits are all "0".
*1 If the class (network address) of the E71 on the own station differs from that of the connected device, set the network
address of the connected device.
*2 If the class (network address) of the E71 on the own station is the same as that of the connected device, set the subnet
