Check

Instrument is in use by another PC, or Socket Port number is incorrect!

Instrument not found!

Each instrument can be controlled by only one host computer.

The instrument did not respond to the host computer.

Verify that socket ports match. See “Setting the Socket Port” in Chapters 2 and 3 of this manual.

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.
