DESCRIPTION
ICS's 4865 is a GPIB-to-LAN Instrument
Interface that enables a VXI-11.3 compatible
LAN instrument to be controlled from a GPIB
Bus. Using the 4865, GPIB applications run-
ning on a computer can transparently interface
to a LAN-based instrument just as if it were
a GPIB Instrument. The 4865 converts 488.1
GPIB commands into the equivalent VXI-
11 RPC and sends them to the instrument.
Device messages are transparently sent to
the instrument and instrument replies are
returned to the GPIB Controller, just like a
GPIB instrument.
The 4865 solves the problem of how to
interface an instrument with an Ethernet
interface to the GPIB bus. The 4865 adds a
GPIB interface to VXI-11.3 compatible LAN
or LXI instruments that do not have a GPIB
interface. Applications include replacing
obsolete or failed GPIB instruments with a
newer instrument that may not have a GPIB
interface or just adding a new LAN instru-
ment to a GPIB bus system.
Linking to the Instrument
The 4865 operates with any VXI-11.3 com-
patible instrument which includes most LAN
and some LXI instruments (The LXI Speci-
fi cation only requires a minimum VXI-11
compatibility, so check VXI-11 compatibility
with your LXI instrument manufacturer.)
The 4865 can be set to operate with an
instrument at a specifi c IP address or to
automatically fi nd the instrument. Either
method can be used in a
direct 4865-instrument
connection.
If AutoFind is se-
lected, the 4865 starts
an instrument discov-
ery process as soon as
it completes its power
turn-on and self-test
sequence. The instrument and the 4865's
IP address must be in the same IP address
B range for Auto Find to work. When the
4865 fi nds a VXI-11.3 instrument, it opens
a core channel to the instrument.
If the 4865 has been given a specifi c
instrument's IP address, the 4865 only looks
for an instrument at that address. Static
address are recommended when the 4865
is connected to the company network or
when multiple instruments may respond to
the 4865.
Minimal Programming Changes
In most cases, existing programs that
controlled the instrument in a LAN en-
vironment or ran the older version of the
instrument through its GPIB interface can
be used with the 4865 and the LAN instru-
ment. The only requirement is that the new
instrument must understand your existing
commands. The 4865 works with any IEEE-
488.2 compatible GPIB controller and can
be used with LabVIEW, VEE, Visual Basic
and C language programs. The 4865 and
VXI-11.3 instruments support most 488.1
