Configuring I/O Interfaces
Configuring LAN Interfaces
Example:
Configuring VISA
LAN Client (LAN)
Interface
The VISA LAN Client interface system in the following figure consists of a
Windows PC with a LAN card and three LAN instruments. Instrument1 and
instrument2 are VXI-11.2 (GPIB Emulation) instruments and instrument3 is
a VXI-11.3 LAN instrument.
For this system, the IO Config utility has been used to assign the LAN card
a VISA name of “TCPIP0” and SICL name of “lan”. In addition, two VISA
LAN Clients have been configured with the interface names and host names
shown in the figure.
For the addressing examples, instrument1 has been addressed by its
machine name, instrument 2 has been addressed by its IP address, and
instrument3 by its LAN name (inst0).
Since unique names have been assigned by IO Config, you can now use the
VISA viOpen command or the SICL iopen command to open the IO paths
to the GPIB instruments as shown in the figure. Note, however, that you
cannot talk to instrument3 with VISA LAN Client. You must use the LAN
Client (with VISA or SICL) to talk to instrument3, since instrument3 is not a
remote gpib interface.
See the Agilent VISA User’s Guide for details on VISA commands. See the
Agilent SICL User’s Guide for Windows for details on SICL commands.
NOTE
When using the VXI-11 protocol with VISA LAN Client, the Remote SICL
Interface Name must be of the form gpibN where N is 0 or a positive
integer. This restriction does not apply to the SICL-LAN protocol.
