PC to VME interface

The interface between a PC and the VME bus is done by a a PCI-VME 8000 from National Instrruments. It consists of two cards. One resides in the PCI-bus of the PC the other one in the VME-crate (slot 0, but i don't know if it has to be in 0). Both cards are connected by a cable. We are running Windows NT.

Set up (once)

The NI interface comes with various software and interactive tools. The first step is to let the interface know that there is a DSP in the VME-crate and which memory space it is using.

• use the VXIedit, (item: Non-VXI Device Configuration Editor).
• create a new module (call it DSP for example) with:
  1. A16 and A32 address set to 0
  2. A24 base is the DSP base address (see dip switch on your DSP card).
  3. A24 size 10000.
  4. Frame = 1 (important).
  5. Slot = 3 (this does not matter).
  6. for all the other items put in what ever you like.

Running the interface from a program

The VXIinit and Resman programs have to be run, before the VXI-library functions can be called from a program.

1. run VXIinit
2. run Resman
3. run your program
