Web Interface - Keithley 2450 Reference Manual

Model 2450 Interactive SourceMeter® Instrument Reference Manual Section 2: General operation
VXI-11 connection
This remote interface is similar to GPIB and supports message boundaries, serial poll, and service
TM
requests (SRQs). A VXI-11 driver or NI-VISA software is required. Test Script Builder (TSB) uses
NI-VISA and can be used with the VXI-11 interface. You can expect a slower connection with this
protocol.
Telnet connection
The Telnet protocol is similar to raw socket, and can be used when you need to interact directly with
the instrument. Telnet is often used for debugging and troubleshooting. You will need a separate
Telnet program to use this protocol.
The Model 2450 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.

Web interface

When a connection between the LAN and the instrument has been established, you can open a web
page for the instrument.
To access the web interface:
1. Open a web browser on the host computer.
2. Enter the IP address of the instrument in the address box of the web browser. For example, if the
instrument IP address is 192.168.1.101, enter 192.168.1.101 in the browser address box.
3. Press Enter on the computer keyboard to open the instrument web page.
4. If prompted, enter a user name and password. The default is admin for both.
If the web page does not open in the browser, see LAN troubleshooting suggestions (on page 2-60).
