VXI-11 Keyboard Control Program provides
interactive control of VXI-11 instruments from
the computer keyboard without having to write a
program. The VXI-11 Keyboard program is the
ideal utility program for con
fi guring and testing
the PRS or any VXI-11 compatible instrument.
Use the VXI-11kybd program to exercise the
interface or to try out commands before using
them in a program. The VXI-11kybd program
can be found on the PRS product page at www.

Versatile Programming
The PRS-330 can be easily controlled by several
programming techniques and languages because
it is a VXI-11.3 instrument. If you program
with LabVIEW, National Instruments’ VISA
supports VXI-11.3 instruments like the PRS. NI’s
Measurement and Automation Explorer treats
the PRS as a TCP/IP compliant device. Agilent’s
VISA library supports VXI-11.3 instruments and
the Agilent Connection Manager sees the PRS as
a TCP/IP instrument.
If you are a Visual Basic, VB.Net or C/C++
programmer, you can write your program to
call Agilent’s or National Instruments’ VISA
or Agilent’s SICL library in the Windows
environment.
If you use LINUX or any other fl avor of UNIX
like SunOS, IBM-AIX, HP-UX, or Apple’s OS X,
you can communicate with the PRS through RPC
over TCP/IP. RPC (or Remote Procedure Calls)
provides an invisible communication medium for
the developer. The VXI-11 speci
fi cation provides
an RPCL (Remote Procedure Call Library) that
can be used by virtually any operating system to
control the PRS.
If you program with Java then you can write a
PRS control program that can be easily moved
to many different operating systems.
The Java jGpibEnet project on SourceForge was
developed using an ICS 8065 Controller similar
to the PRS Controller.
5.4 Network Confi guration
This paragraph con fi gures the 9006 card in the
PRS for operation on your network. The board’s
digital interface is con
fi gured later by sending
commands as outlined in Appendix A.
When shipped, the boards are con fi gured with
default settings outlined in Table 4-1 Default
Settings.
Command Function Factory Setting
IP Mode Static or DHCP
Mode Static
IP Address 0.0.0.0 to
255.255.255.255.0 192.168.1.254
Net Mask 0.0.0.0 to
255.255.255.255.0 255.255.255.0
COMM Timeout Sets socket timeout 120 sec.
Auto Disconnect Aborts socket if link
count goes to 0 Off
Table 4-1 Default Settings
Review the Table with your network administrator
and decide on which settings, if any, that need
to be changed. Table 4-1 provides detailed
information about each network setting to help
you with your decisions. The minimum change
is to set a static IP address so your PC can
communicate with the board.
