Monitoring the LAN
The lan.autoconnect command configures the instrument to monitor the LAN for lost connections.
All ethernet connections are disconnected if the LAN link is disconnected for longer than the time-out
value specified in the lan.linktimeout attribute.
For detail on these commands, refer to the following command descriptions:

GPIB operation
The following topics contain information about GPIB standards, bus connections, and primary
address selection.
GPIB standards
The GPIB is the IEEE-488 instrumentation data bus, which uses hardware and programming
standards originally adopted by the Institute of Electrical and Electronic Engineers (IEEE) in 1975.
The instrument is IEEE Std 488.1 compliant and supports IEEE Std 488.2 common commands and
status model topology.
Connect the GPIB cable
To connect an instrument to the GPIB bus, use a cable equipped with standard IEEE-488 connectors,
as shown below.
