3 Getting Started

		DNS
		Select DNS to configure the Domain Name System (DNS) setup of the
		instrument. DNS is an internet service that translates domain names
		into IP addresses. It is also needed for the instrument to find and
		display its hostname assigned by the network.
Obtain DNS server		Select this item to obtain the DNS server address from DHCP. You must
	from DHCP	have enabled DHCP in the IP menu.
	Use the following	Select this item if you are not using DHCP or need to connect to a specific
	DNS server	DNS server.
	DNS Server	This value is the address of the DNS server. It is used if you are not using
		DHCP or if you need to connect to a specific DNS server.
		For improved performance when connected to an isolated subnet, select Use
	NOTE
		the following DNS server. However, leave the DNS server address field blank.

	TCP
	Select TCP to configure the TCP keepalive settings of the instrument.
Enable TCP	Check the Enable box to enable the TCP keepalive function. The instrument
Keepalive	uses the TCP keepalive timer to determine if a client is still reachable. If
	there has been no activity on the connection after the specified time, the
	instrument will send keepalive probes to the client to determine if it is still
	alive. If not, the connection will be marked as down or "dropped." The
	instrument will release any resources that were allocated to that client.
TCP keepalive	This is the delay in seconds before TCP keepalive probes will be sent to the
timeout	client. It is recommended that the largest value be used that still meets the
	application's need for unreachable client detection. Smaller keepalive time-
	out values will generate more keepalive probes (network traffic), using more
	of the available network bandwidth. Allowed values: 720 - 99999 seconds.

LAN Communication

The Agilent IO Libraries Suite along with instrument drivers for specific programming environments can be used to communicate with your power system. You can also communicate with your power system using its built-in Web server, the Telnet utility, or sockets. These latter methods are a convenient way to communicate with the power system without using I/O libraries or drivers. In all cases, you must first establish a LAN connection from your computer to the power system as previously discussed.
