LAN communications
You can communicate with the instrument using a local area network (LAN).
When you connect using a LAN, you can use a web browser to access the internal web page of the
instrument and change some of the instrument settings. For more information, see
(on page 3-11).
The Model 2450 is a LXI version 1.4 Core 2011 compliant instrument that supports TCP/IP and
complies with IEEE Std 802.3 (ethernet LAN). There is one LAN port (located on the rear panel of the
instrument) that supports full connectivity on a 10 Mbps or 100 Mbps network. Speed is automatically
detected.
The Model 2450 also supports Multicast DNS (mDNS) and DNS Service Discovery (DNS-SD), which
are useful on a LAN with no central administration.
Contact your network administrator to confirm your specific network requirements before setting up a
LAN connection.
If you have problems setting up the LAN, see LAN troubleshooting suggestions in the Model 2450
Reference Manual.
Set up LAN communications on the instrument
This section describes how to set up manual or automatic LAN communications on the instrument.
Check communication settings
Before setting up the LAN configuration, you can check the communication settings on the instrument
without making any changes.
To check communication settings on the instrument:
1. Press the
MENU
key.
2. Under System, select
Communication
. The SYSTEM COMMUNICATION window opens.
3. Select one of the four tabs (
GPIB
,
USB
,
LAN
, or
TSP-LINK
) to see the settings for that interface.
4. Press the
EXIT
key to leave the SYSTEM COMMUNICATION window without making any
changes.
Set up automatic LAN configuration
If you are connecting to a LAN that has a DHCP server or if you have a direct connection between the
instrument and a host computer, you can use automatic IP address selection.
If you select Auto, the instrument attempts to get an IP address from a DHCP server. If this fails, it
reverts to a local IP address in the range of 169.254.1.0 through 169.254.254.255.
Both the host computer and the instrument should be set to automatic. Though it is possible to have
one set to manual, it is more complicated to set up.
