Troubleshooting the Initial Connection
Getting the instrument to work with your network often requires
detailed knowledge of your local network software. This section
attempts to help you with some common problems. Contact your
network administrator for additional assistance.
The instrument LAN interface does not need or include any proprietary
driver software. It was designed to operate with common network
utilities and drivers.
Either a hardware problem or a software problem can prevent the
instrument's remote file server from communicating over the LAN. The
following common problems may be encountered:
Communications Not Established If you have just installed and
configured the LAN interface and you have never been able to access
the instrument via ftp or telnet, go directly to

includes adding or removing any workstations or peripherals, or
changing any cabling.
o Have software applications been added to the network?
o Have any configuration files been modified?
o Is the upper- and lower-case character usage in your host name
