Configuring I/O Interfaces
Configuring LAN Interfaces
Example:
Configuring LAN
Client (LAN)
Interface
The 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”. 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 I/O paths
to the GPIB instruments as shown in the figure. See the Agilent VISA User’s
Guide for details on VISA commands. See the Agilent SICL User’s Guide for
details on SICL commands.
