2: Installation 2470 High Voltage SourceMeter Instrument
2-24 2470-901-01 Rev. A / May 2019
The 2470 supports the Telnet protocol, which you can use over a TCP/IP connection to send
commands to the instrument. You can use a Telnet connection to interact with scripts or send
real-time commands.
Dead socket connection
The dead socket termination (DST) port is used to terminate all existing ethernet connections. A dead
socket is a socket that is held open by the instrument because it has not been properly closed. This
most often happens when the host computer is turned off or restarted without first closing the socket.
This port cannot be used for command and control functions.
Use the dead socket termination port to manually disconnect a dead session on any open socket. All
existing ethernet connections will be terminated and closed when the connection to the dead socket
termination port is closed.
Reset LAN settings
You can reset the password and the LAN settings from the rear panel by inserting a straightened
paper clip into the hole below LAN RESET.
LAN troubleshooting suggestions
If you are unable to connect to the web interface of the instrument, check the following items:
• The network cable is in the LAN port on the rear panel of the instrument, not one of the
T
SP-Link
®
ports.
• The network cable is in the correct port on the computer. The LAN port of a laptop may be
di
sabled when the laptop is in a docking station.
• The setup procedure used the configuration information for the correct ethernet card.
• The network card of the computer is enabled.
• The IP address of the instrument is compatible with the IP address on the computer.
• The subnet mask address of the instrument is the same as the subnet mask address of the
c
omputer.
You can also try restarting the computer and the instrument.
To restart the instrument:
1. Turn the power to the instrument off, and then on.
2. Wait at least 60 seconds for the network configuration to be completed.
