LAN interface
Use a network cable to connect PC through LAN interface of the power meter.
•
IP mode
MANU: manually set IP address, subnet mask, default gateway, etc.
DHCP (Dynamic Host Configuration Protocol)
DHCP refers to a protocol that temporarily assigns necessary information to PCs connected to the Internet. If
the network is provided with an available DHCP server, the server will automatically assign information (IP
address, subnet mask and default gateway) to PCs and other equipment connected to the network. IT9121
cannot use DHCP unless the network is provided with a DHCP server. Please ask your network administrator
DHCP if DHCP is available.
•
IP Address
IP addresses assigned to IT9121 can be set. Default address is 192.168.000.000.
•
IP address refers to ID assigned by the network to each equipment (Internet or enterprise Intranet).
•
IP address refers to four 32-bit values within 0 - 255 which are separated by decimal points, such as
[192.168.111.24].
•
Please ask the network administrator to provide an IP address.
•
Use DHCP network to automatically set the IP address.
•
Subnet masksetting
The mask used when subnet website is determined from an IP address may be set. Default address is
255.255.255.255.
•
Vast TCP/IP networks like Internet are often divided into several small networks, i.e. subnets. The subnet
mask is used to identify how many digits of the 32-digit values in the IP address belong to the subnet
address. The part beyond the network address is used to identify the host number of each PC connected to
the network.
•
Ask your network administrator about values of subnet mask.
•
Use DHCP network to automatically set the subnet mask.
•
Gatewaysetting
IP address of gateway may be set to communicate with equipment in other network (default gateway).
Default address is 192.168.000.000.
•
The default gateway controls data exchange between networks and protocols to ensure smooth data
transmission.
•
Ask your network administrator about values of default gateway. It is possible that the setting is
unnecessary.
Use DHCP network to automatically set the default gateway.
