Each instrument can be
controlled by only one
host computer.
Verify that socket ports match. See

and 3 of this manual.
Instrument not found! The instrument did not
respond to the host
computer.
First, try again. If the message occurs
again, verify the following in the order
listed:
1. Instrument is powered. (The front panel
display, when quiescent, shows the
instrument BCN.)
2. Instrument is connected to the network.
3. Instrument BCN (displayed on the front
panel) matches the BCN displayed on
the Instruments on Network list.
4. Network cabling provides a solid
connection.
5. Instrument is configured for the correct
network type (isolated or general).
6. IP address of instrument matches the
IP address displayed on the
Instruments on Network list (on a
general network).
If the problem persists:
1. Move the instrument adjacent to the
host computer and make a direct
connection between the two. See
“Host Computer/Instrument Direct
Connection” in this chapter.
