Here are some topics that have come up while helping people get an NI-1014
board working ...

JUMPERS

W1 :  0x50    (Base Address = 0x5000 in the A16 address space for Link 0)
W2 :  S       (use "supervisory" access)
W3 :  1       (Default Setting)
W4 :  1       (Default Setting)
W5 : AM1'     (Default setting)

ATTENTION :
The NI-1014 is a DMA device AND an interrupting device, so it must be placed
ADJACENT to other VME modules with no empty slots between it and the CPU (or
install appropriate jumpers on the VME back plane).

VxWorks BOARD SUPPORT 
The "as shipped by Wind Rivers" board support for the MVME167 DOES NOT
WORK with the NI-1014. Modification must be made to properly configure the
memory management chips such that the 1014 can write to CPU memory (as a DMA
device. The modified one for the 167 is available from Argonne. Others have 
done one for the 147. If you are using a different CPU, be forewarned !

GPIB Interact
There is a very useful program distributed with EPICS that 
allows one to send/receive GPIB data interactively to an instrument
without ANY device support. This is a great tool to confirm the 1014 is
working AND to better understand how your instrument communicates.

In 3.13, edit xxApp/src/baseLIBOBJS to include 
  LIBOBJS += $(EPICS_BASE_BIN)/devGpibInteract.o

After the ioc boots, type GI (GPIB Interact) to start the menu driven program.

DEVICE Support

The 'skeleton' device support (and other examples) are distributed in 

   baseR3.13.0.beta11/src/devOpt

What seems to have worked even better for people is to find an
existing device support for a device SIMILAR to yours and simply
change the format strings for commands and responses. A simple
tech-talk message may help you find one really similar.

ALSO, there is the 'generic GPIB' record available from APS (written
by Mark Rivers) which avoids device support all together. You simply
write the command string to the record and read the response.

	Hope this helps.
