VINStrument[:CONFigure]:VME[:MODE]

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 + 4316). This bit goes high when the data is again ready for transfer. See Chapter 3 for additional information.

*RST Condition: None

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 (0C16) in A24 address space.
