Question : How do I close the port on the 2701 to enable me
to communicate with the instrument after a dropped
connection.
Answer: The 2701 allows a single connection to the instrument at
a time. Beginning with firmware version A06, an update was done
to enhance the ability of the 2701 to sense when the connection is
lost from the host program and close the connection
automatically. If you have an earlier version of the firmware, you
can obtain version A06 from our web site.
An additional feature was added to allow the connection to be
closed manually from a remote location. If the connection is lost
due to a network failure between the 2701 and the computer that
is communicating, a second port is now available to allow the
main connection to be closed. This is done by opening up port
number 2842 and sending the SCPI command
":SYSTem:ETHernet:SOCKet:RESet". This will close the main
connection on port 1394. Once this has been done, port 1394 will
again accept a connection request to resume normal
communications. Note that any commands or transfers that were
in progress when communications were lost may not have been
processed. Port 2842 is only able to accept the
":SYSTem:ETHernet:SOCKet:RESet" command. All other
instrument commands must be sent to 1394.
