Nonvolatile Configuration
This chapter describes the method for editing and reviewing the contents
of the nonvolatile memory, which is used for storing configuration
information on the GPIB-VXI/C.
The GPIB-VXI/C nonvolatile (NV) memory is a 256-byte EEPROM that is
accessible as 64 longword locations. The first half of the NV memory
(32 longwords) is reserved for use by National Instruments. The second
half of NV memory is allocated for storing Code Instrument (CI)
configuration variables.
Note
National Instruments no longer supports development of Code Instruments.
The configuration parameters include the following:
•
Local register configuration
•
pSOS configuration
•
VXI interrupt line assignment
•
Resource Manager (RM) A24 and A32 address assignment base
•
Servant area size
•
DC starting logical address and hierarchy configuration
•
Device failure mode
•
GPIB configuration
•
Default CI configuration
•
CI RAM area configuration
•
Resident CI locations
•
CI user configuration variables
You can enter NV configuration mode through either of the following
methods:
•
Set the startup mode switches to the nonvolatile configuration mode as
described in the
GPIB-VXI/C Startup Mode Configuration
section of
Chapter 2,
Configuration and Startup Procedures
. For this mode, set
