Using the LAN to Control the Instrument
Programming Fundamentals
— Check the physical connection to the LAN.
— Make sure the internet (IP) Address of the instrument is set up
correctly in the LAN port setup menu. (Press
System, Controls, IP
Admin
.)
— When connecting to your instrument over a closed network
(directly through a hub or crossover cable) it may help to set the
instrument to its default settings for subnet mask and gateway.
(subnet mask: 255.255.0.0, gateway 0.0.0.0)
— If the instrument and the computer are on different networks or
subnets, make sure the gateway address and subnet mask values
are set correctly.
Cannot access the file system via ftp
• If you get a “connection refused” message, try the following
solutions:
— If the power to the instrument was just turned on, make sure that
you wait about 25 seconds before attempting the connection.
• If you get a “connection timed out” message
— Verify the LAN connection between your computer and the
instrument. Refer to “If you cannot connect to the instrument”
earlier in this section.
Cannot telnet to the command parser port
• For a “connection refused” message
— Check the telnet port number from the front-panel keys.
• For a “connection timed out” or “no response from host” message
— Verify the LAN connection between your computer and the
instrument. Refer to “If you cannot connect to the instrument”
earlier in this section.
• For a “connection refused” or “no response from host” message
— If the instrument was just turned on, make sure that you wait
about 25 seconds before attempting the connection.
An “operation timed-out” message
• Check the LAN connection between the computer and the
instrument. Refer to “If you cannot connect to the instrument” in
this section.
• Increase the file time-out value on your PC or workstation.
