Explanation
The following TCP/IP settings must be entered to use the Ethernet communications
functions on the SL1400.
• IP address
• Subnet mask
• Default gateway
IP Address (Internet Protocol Address)
Set the IP address to assign to the SL1400. The default setting is “0.0.0.0.”
The IP address is an ID that is assigned to each PC 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. The setting is automatically
configured in environments using DHCP.
Subnet Mask (Net Mask)
Set the mask value used when determining the subnet network address from the IP
address. The default setting is “255.255.255.0.”
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 PCs on the network.
Consult your network administrator for the subnet mask value. You may not need to set
the value. The setting is automatically configured in environments using DHCP.
Default Gateway
Set the IP address of the gateway (default gateway) used to communicate with other
networks. The default setting is “0.0.0.0.”
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. The setting is automatically configured in environments using DHCP.
DHCP (Dynamic Host Configuration Protocol)
DHCP is a protocol that allocates setup information that are needed temporarily to the
PCs connecting to the network. When DHCP is turned ON, the following settings are
automatically assigned.
• IP address
• Subnet mask
• Default gateway
• DNS
To use DHCP, the network must have a DHCP server. Consult your network
administrator to see if DHCP can be used.
When DHCP is turned ON, different settings may be assigned each time the power is
turned ON. When using the FTP server function (see section 15.6), be sure to check the
IP address and other settings of the SL1400 using a PC or workstation each time you
turn ON the SL1400.
