What can I do to make sure that my system is up and running?
The fastest method for testing the system is to run Resman. This program
attempts to access memory in the upper A16 address space of each device
in the system. If Resman does not report any problems, the VXI-8340 series
communication system is operational.
To test individual devices, you can use the VIC or VISAIC program
to interactively issue NI-VXI functions or NI-VISA operations,
respectively. You can use the
VXIin()
and
VXIout()
functions or the
VXIinReg()
and
VXIoutReg()
functions to test register-based devices
by programming their registers. If you have any message-based devices,
you can send and receive messages with the
WSwrt()
and
WSrd()
functions. Notice that
VXIinReg()
and
VXIoutReg()
are for VXI
devices only, but you can use
VXIin()
and
VXIout()
for both VXI
and VME.
Finally, if you are using LabVIEW or LabWindows/CVI and you
have instrument drivers for the devices in your chassis, you can use the
interactive features of these programs to quickly test the functionality of
the devices.
What should I do if I get a
Configuration EEPROM is Invalid
message?
There are several reasons why you might get the
Configuration EEPROM
is Invalid
message. If you turned off the VXI chassis while the
configuration update process was still in progress, the module functions
normally except when running MAX. To correct these problems, reboot the
VXI chassis with the Load Factory switch set (as described in Appendix C,
Advanced Hardware Configuration Settings
) and update the configuration,
or load the configuration from file.
What do the LEDs on the front of the VXI-8340 series mean?
•
The
FAIL
LED indicates that the VXI-8340 is driving SYSFAIL onto
the backplane.
•
The
ONLINE
LED indicates when the VXI-8340 series is online.
When it is offline, you can safely power cycle the VXI chassis.
•
The
Link 1
LED indicates that a communication path has been
established with the device attached to MXI IN.
•
The
Link 2
LED indicates that a communication path has been
established with the device attached to MXI OUT.
•
The
SYSF
LED indicates that the VMEbus SYSFAIL line is asserted.
