Check connections.
It is possible that more than one NIC is present on
the PC.
Select network connections settings on the computer,
plug in the cable, and check if the status changes
from unplugged to connected.

Ask network administrator for details.
Ask network administrator for details.
The IP address has to be in the correct range such
that both the instrument and the PC are in the same
network and subnetwork.
Straight wired Cat. 5 LAN cable is used for most
setups. The only exception is if a direct connection
from PC to instrument is used and the NIC does not
have Auto-negotiation or Auto-sensing (the
possibility to detect the correct transmission
parameters and set them accordingly between NICs).
The network administrator may support and check:
MDI-X
Auto MDI(X)
Ports are used within the network.Check if straight
or crossed wired cable (vice-versa) solves the
problems, or work with a corresponding LAN
adapter (MDI) to test the communication.
