3. To select the digit to adjust, press either  or .
With the desired digit selected, press the soft key labeled  to decrement the digit
or  to increment the digit.
4. Press the  soft key.
The new Network Socket Port becomes effective immediately.
Note
The Network Socket Port Number is stored in non-volatile memory.
Establishing an Ethernet Connection
The easiest method of establishing an Ethernet connection with the Meter is through the
commonly available program: Telnet. Telnet is a client-server protocol, based on TCP.
The Telnet Protocol provides a fairly general, bi-directional, eight-bit byte oriented
communications facility. Telnet is available on all UNIX servers and on most PCs.
Telnet clients typically connect to hosts on socket port 23. The LAN connection to the
Meter must be established using the specified Network Socket Port. See the “Configuring
the General Network Socket Port” section above. When the remote interface port is
changed to LAN from the Meter’s front panel, a LAN server is initiated in the Meter
which listens for client connections on the socket port at the specified IP address.
To establish a LAN connection to the Meter from a computer using either UNIX,
LINUX, or MS-DOS command prompts, perform the following procedure:
1. On the Meter’s front panel, change the remote interface port to LAN
2. At the command prompt on the client computer, enter:
telnet <IP Address> <Socket Port>
Alternatively, if you are using DHCP and would like to connect using the host name
rather than the IP address, from the computer command prompt enter:
telnet <Domain Name> <Socket Port>
As an example, if you know the IP address is 129.196.136.131 and the Socket Port is set
to 3490, enter the following at a command prompt from any client computer:
telnet 129.196.136.131 3490
If you are using DHCP and the host name is test1 and the fully qualified domain name is
test1.na.flukecorp.com and the Socket Port is set to 3490, enter the following at the
computer command prompt:
telnet test1.na.flukecorp.com 3490
Once the internal LAN server connects with the client computer, the LAN server will
reject any other connection attempts by other computers and will “tunnel” a channel to
the connected computer. This prevents multiple computers from trying to control the
Meter at the same time.
