IP Address Assignment
Each device must have a unique IP address, as controlled by the
RIR (Regional Internet Registry).
IP address assignment is controlled by the NIC (Network Informa-
tion Center) of each country. You have to apply for assignment of
an IP address from your country's NIC.
Besides the IP addresses and global IP addresses controlled by
the NIC, the following addresses are defined as private IP
addresses in the RFC1597.
10. 0.0. 0/8 10. 0.0.0 to 10.255.255.255
172. 16.0.0/12 172. 16.0.0 to 172. 31.255.255
192.168.0.0/16 192.168.0.0 to 192.168.255.255
You can use these private IP addresses freely. However, you can-
not connect to the Internet directly with these addresses.
Select a private IP address when you make a one-to-one connec-
tion between the instrument and a PC using a cross cable or when
you build a closed network using the HUB only. If, however, all the
bits of the host address are 0, the address will be used as a net-
work address showing the subnetwork. If all the bits of the host
address are 1, the address will be used as a broadcast address
showing all the hosts on the subnetwork. In these cases, the
address cannot be used as the IP address of the device.
For example, if the network is 192.168.1.0/24, the address
192.168.1.255 shows all the devices connected to the subnet of
192.168.1.0. On this subnet, you can use a total of 254 IP
addresses between 192.168.1.1 and 192.168.1.254; the
addresses 192.168.1.0 and 192.168.1.255 would be excluded.
Port Number
With the TCP/IP protocol used by this instrument, connections can
be made separately for every application. These connections will
be distinguished by port number. The instrument is set to use
8800-8809 as the default setting.
8800 (The instrument is the server.) : using the 9334 LOGGER COMMUNICATOR
8801 (The instrument is the client.) : using the 9334 LOGGER COMMUNICATOR
8802 (The instrument is the server.) : controlled by communications commands.
8803 to 8809 : reserved
The settings above do not need editing, unless use of some port
numbers is restricted for security reasons if or some port numbers
cannot be used on the PC. You can edit the left three digits only.
The rightmost digit (0 to 9) is used by or reserved for the instru-
ment.
