104 Agilent Connectivity Guide
5 Connecting Instruments to LAN
Agilent Connection Expert automatically locates, identifies, and
verifies all LAN instruments that use either the VXI-11 or the
SICL-LAN protocol on your local subnet and lists them in the
display. This may take a few minutes; please be patient.
.
3 Click the Select check box for each instrument you want to include
as part of your test system. Click the OK button to verify each
selected instrument and add it to the Connection Expert Explorer
Pane. Refer to “Newly Added LAN Instrument in Connection
Expert” on page 112. Proceed to “Step 4: Communicate with
Instruments” on page 114.
What if it didn’t find my instrument? If the Connection Expert
Auto Find (default tab) did not find one or more instruments:
• Verify that AutoIP is not
used in any instrument AND if your PC
has multiple NICs, that each NIC has a different network address.
• If instrument(s) are not on the same local subnet as the PC and
you know the instrument IP address or hostname, use the Add
Address tab. Refer to “Connecting a LAN instrument outside your
local subnet” on page 105.
• If instrument(s) are not on the same local subnet as the PC and
you don’t
know the instrument IP address or the Hostname, use
the Search tab.Refer to “Searching for LAN instruments” on
page 106.
• To find GPIB or USB instruments on a LAN portal, refer to
“Connecting a GPIB, USB, etc. instrument on a LAN
Gateway” on page 108.
NOTE
A separate UDP broadcast is sent to the broadcast address of each NIC.
This broadcast address is the network part of each NIC's IP address with
the subnet part set to all 1's. The PC network stack uses the network part
of the address to determine which NIC to route the broadcast packet to.
In addition a UDP broadcast of 255.255.255.255 is also sent. It is this
address that will pick up AutoIP instruments whose network addresses
aren't consistent with the subnet they are connected to. MS Windows
will only send the 255.255.255.255 packet to one NIC. That is the only
NIC where AutoIP'd instruments will be found. Use the Add Address or
Search tab to locate other instruments.
