Explanation
To use the network function of the VB8300, the TCP/IP parameters must be configured.
DHCP (Dynamic Host Configuration Protocol)
DCHP is a protocol that allocates setup information that is needed temporarily to PCs
connecting to the network. When DHCP is turned ON, the following settings are
automatically assigned.
IP address
Subnet mask
Default gateway
Broadcast
DNS
• To use DHCP, the network must have a DHCP server. Consult your network
administrator to see if DHCP can be used.
• If DHCP is switched from OFF to ON, it may take several tens of seconds before the
IP address can be retrieved.
• When DHCP is turned ON, different settings may be assigned each time the power is
turned ON. When accessing the VB8300 from a PC, you must check the VB8300
TCP/IP settings such as the IP address each time the power is turned ON.
IP Address (Internet Protocol Address)
You can set the IP address assigned to the VB8300.
• The IP address is an ID that is assigned to each device on an IP network such as the
internet or an intranet.
• The address is a 32-bit value expressed using four octets (each 0 to 255), each
separated by a period as in [192.168.111.24].
• Obtain an IP address from your network administrator.
• This parameter is automatically configured in environments using DHCP.
Subnet Mask
You can set the mask value used when determining the subnet network address from
the IP address.
• Huge TCP/IP networks such as the Internet are often divided up into smaller networks
called sub networks. The subnet mask is a 32 bit value that specifies the number of bits
of the IP address used to identify the network address. The portion other than the
network address is the host address that identifies individual computers on the network.
• Consult your network administrator for the subnet mask value. You may not need to
set the value.
• This parameter is automatically configured in environments using DHCP.
Default Gateway
You can set the IP address of the gateway (default gateway) used to communicate with
other networks.
• The default gateway has control functions that handle protocol exchanges when
communicating with multiple networks, so that data transmission is carried out
smoothly..
• Consult your network administrator for the default gateway value. You may not need
to set the value.
• This parameter is automatically configured in environments using DHCP.
Broadcast
You can set the IP address of the broadcast segment (a collection of networks). This is
used to send (broadcast) the same packets to all hosts (devices connected to the
network) in the specified segment.
