Instrumentation connection to enterprise routers or servers
This connection uses an existing network infrastructure to connect instruments to the computer
controller. In this case, you must get the network resources from the network administrator.
Usually, the instruments are kept inside the corporate firewall, but the network administrator can
assign resources that allow them to be outside the firewall. This allows instruments to be connected
to the Internet using appropriate security methods. Data collection and distribution can be controlled
from virtually any location.

Raw socket connection
All Keithley instruments with LAN connections support raw socket communication. This means that
you can connect your computer 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.
Beginning with firmware version 1.06 and later, the raw socket port number changed to 5025. For
firmware versions 1.06 and earlier, the raw socket port number is 5050.
