VINStrument:CONFigure:VME:FEED. However, if these settings were not in
effect when the measurement was taken, then
VINStrument:CONFigure:VME:MEMory:INITiate must be sent before data is
retrieved from memory via the data register.
This command results in an error if VINStrument:CONFigure:VME:MODE is OFF.
This command has no query form.
Comments • Executable when initiated: No
• Coupled command: Yes, this command will error if
VINStrument:CONFigure:VME:MODE is OFF, or if the HP E1429 is already
initiated or transferring data.
• If the data in memory is in multiple segments, then there will be a small time
delay (630 µs) between segments while the CPU switches the memory address to
point to the next segment. It is possible to determine when data is available again
by monitoring bit 1 of the A24 arm status register (base + 43
16
). This bit goes
high when the data is again ready for transfer. See Chapter 3 for additional
information.

Example Send channel 2 of memory data out over the VXIbus, whenever the VME data
register is accessed
VINS:VME:MODE GEN Set mode to GENerate
VINS:VME:FEED "MEM:CHAN2" Set data source to be memory channel 2
VINS:VME:MEM:INIT Begin sending data to VXIbus when the
VME A24 register is read
[:CONFigure]:VME[:MODE]
VINStrument[:CONFigure]:VME[:MODE] <mode > selects the operating mode
for the VME bus. The only available modes are GENerate and OFF.
This command is used when it is desirable to transfer data over the VME bus by
reading the data register at offset 12 (0C
16
) in A24 address space.
