Terminating an Ethernet Connection

When you wish to terminate the Ethernet connection, you may do so one of two ways:
1. Change the Meter's remote interface port to something other than LAN
2. Terminate the Telnet session on the client computer
If you have established a LAN connection to the Meter using Telnet and change the
remote interface port using the Meter's front panel, the LAN server in the Meter will
automatically terminate the Telnet session on the client computer.
On the other hand, you may wish to terminate the Telnet session on the client computer
but maintain the current LAN remote interface port configuration. To do this, you
terminate the Telnet session on the client computer. Client Telnet session termination
can vary from computer to computer, but typically terminating the shell (or command
window in DOS) will terminate the telnet session. When the client terminates the Telnet
session, the LAN server in the Meter will go back into listen mode waiting for a new
client to make a LAN connection request.

Selecting the Programming Language

The Meter's remote command set is switchable between 8845 and Fluke 45 commands.
The Meter's standard remote command set (8845) is compatible with Agilent's 34401A
command set. Although every effort was made to make the Meter compatible with Fluke
45 commands, there are some commands that are not compatible. See Appendix B,
"Fluke 45 Emulation Limitations" for details on commands that are not compatible with
this Meter.
To change the Meter's remote command set:
1. Press I.
2. Press the COMMANDS soft key.
3. Press the soft key labeled with the desired command set.

Getting Started With an Installation Test

After the Meter has been cabled to a host, and prepared to communicate with it via the
RS-232 or IEEE 488 interface (as described above), test the system to verify that it is
operational.

Installation Test for RS-232 Connections

The procedure below illustrates how the Meter performs a computer interface command
and, at the same time, confirms that the Meter has been properly set up and connected for
RS-232 remote operations:
1. Press the POWER button in to turn the Meter on.
2. Start up a computer terminal program.
3. Verify that the computer interface parameters (e.g., baud, parity) are set correctly.
4. Send the Meter the following command.
5. Verify that the Meter sends the following response:
