LAN interface protocols
You can use one of following LAN protocols to communicate with the 2470:
•
Telnet
•
VXI-11
•
Raw socket
You can also use a dead socket termination port to troubleshoot communication problems.
You can only use one remote interface at a time. Although multiple ethernet connections to the
instrument can be opened, only one can be used to control the instrument at a time.
The port numbers for the LAN protocols and dead socket termination are listed in the following table.

Raw socket connection
All Keithley instruments that have LAN connections support raw socket communication. This means
that you can connect to the TCP/IP port on the instrument and send and receive commands. A
programmer can easily communicate with the instrument using the Winsock API on computers with
the Microsoft
®
Windows
®
operating system or using the Berkeley Sockets API on Linux
®
or Apple
®
computers.
VXI-11 connection
This remote interface is similar to GPIB and supports message boundaries, serial poll, and service
requests (SRQs). A VXI-11 driver or NI-VISA
TM
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.
