Machne Name

To distinguish individual MX100s, you can enter a name that is easy to identify using up
to sixty-four characters (not required).

IP Address

Enter a new IP address to assign to the MX100. The default address is 127.1.1.XX (where
XX is a unique number for the device). This address cannot be used even when the
PC and the MX100 are connected in a one-to-one configuration. You must change to a
different address such as 192.168.1.XX (where XX is a value between 1 and 254). When
connecting the PC locally, do not set the PC to obtain the IP address automatically. Enter
the IP address manually to an address other than the one that is to be assigned to the
MX100 (192.168.1.100 if 192.168.1.1 was assigned to the MX100, for example).

Note

• To connect to the MX100 by entering a host name in the IP Address or Host Name box, the

host name (name used on the TCP/IP network) must be registered in a DNS server and the
DNS server must be connected to the network. However, the MX100 Standard Software
does not have a function for registering host names on the DNS server. For the procedure of
registering host names, consult your network administrator.

• To initialize all settings including the IP address to the their factory default values, see

“Initializing the Settings” in section 2.6 of the MX100 Data Acquisition Unit User’s Manual (IM
MX100-01E).

Subnet Mask

Enter the mask value used when determining the subnet network address from the IP
address. The default value is 255.255.255.0. When connecting to the PC locally in a one-
to-one configuration, this value does not need to be changed. In this case, set the subnet
mask on the PC to 255.255.255.0 as well.

Note

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.

Default Gateway

Set the IP address of the gateway (default gateway) used to communicate with other
networks. The default value is 0.0.0.0. When connecting to the PC locally in a one-to-one
configuration, this value does not need to be changed. In this case, you do not have to
set the default gateway on the PC.

Note

The default gateway is a router or computer that is used when accessing a computer outside its
own network. Consult your network administrator for the IP address of the default gateway.
