Series N5700 User’s Guide
Service requests are enabled for control sockets using the Service
Request Enable register. Once service requests have been enabled,
the client program listens on the control connection. When SRQ goes
true the instrument will send the string “SRQ +nn” to the client. The
“nn” is the status byte value, which the client can use to determine
the source of the service request.
Configuring the LAN Parameters
To configure the LAN parameters from the instrument’s Web server,
launch the Web server as previously described, and click on the View
& Modify Configuration tab on the left side of the page. Then click on
the Modify Configuration button on the top of the page. The following
screen lets you modify the LAN parameters:
The configurable LAN parameters are described as follows:
IP Address
Configuration
This setting indicates how the instrument will determine its IP Address,
Subnet Mask, and Default Gateway.
If Automatic is selected, the instrument tries to obtain an IP address from a
DHCP server. If a DHCP server is found, the DHCP server assigns an IP
address, Subnet Mask and Default Gateway to the instrument. If no DHCP
server is found, the instrument automatically configures its IP address and
Subnet Mask using Dynamically Configured Link Local Addressing (Auto-IP),
which results in an address in the range 169.254.xxx.yyy.
If Manual is selected, the instrument uses the IP Address, Subnet Mask, and
Default Gateway defined below..
IP Address
This value is the instrument’s Internet Protocol (IP) address. An IP Address is
four decimal numbers from 0 to 255 separated by periods. It is required for all
IP and TCP/IP communications with the instrument.
