Agilent Technologies L4400 manual Configuring the LAN Interface, Instrument Addressing

Software Installation and Configuration 2

Host Names Each L4400 instrument has a default host name. The format of the host name is:

A- L44xxA- yyyyy

where ‘L44xxA’ is replaced by the module number (e.g. L4421A) and ‘yyyyy’ are the last five digits of the instrument serial number.

The instrument host name is reported by Agilent Connection Expert for network servers that support Dynamic Domain Name Service (DNS). For network servers that do not support Dynamic DNS, only the IP address is reported.

Instrument Addressing

During programming, an L4400 series instrument is accessed through its address string which consists of an IP address or host name. For example:

TCPIP0::192:168:1.221::inst0::INSTR

The L4400 series instruments can also be accessed using a host name as part of the address string. For example:

TCPIP0::A-L4450A-12345.agilent.com::inst0::INSTR

NOTE	The L4400 instruments can be restored to their default configurations by
	pressing the ‘Reset’ pin on the instrument’s front or rear panels.

Computer Configuration

Most computers used for instrument/system control are configured for LAN and Internet access. Before starting Agilent Connection Expert to locate and configure the instruments, verify that your computer is able to connect to the network that will include the instruments.

A Web browser is used to open web interfaces to the L4400 instruments (See “Using the Instrument Web Interface”). In some network configurations, a proxy server cannot be used to access the instrument IP addresses. In these situations, the browser must be set to disable the proxy for the instrument’s address.

Configuring the LAN Interface

With the L4400 instrument(s) turned on and connected to a private or site LAN network, start Agilent Connection Expert utility by clicking on the Agilent IO Control icon and selecting “Agilent Connection Expert from the pop- up menu (Figure 2- 5).
