DATB: Setting ICP/IEPE Power on NI devices (again)

Subject: DATB: Setting ICP/IEPE Power on NI devices (again)

Does anybody have any more information about when the ability to
control ICP/IEPE on NI 44XX products will be added to the DATB? We
have requested this feature repeatedly since the beginning. We
developed a work around for Traditional NI-DAQ using the generic DLL
interface (will share with anyone interested), and have code to do
the same with NI-DAQmx but the current version DATB resets the board
upon start and reserves the hardware resources. This means that even
though we can control the ICP power, it gets reset whenever the DATB
start function is called, and you can't get at the hardware to change
the IEPE power. It is not a difficult fix, the DATB supports ICP
power on Agilent boards, but possibly we just need more people to
request it. So far as we can figure out, with the current version of
the DATB you cannot use any of the NI products (any bus) with ICP
power if you need to control the state of the power. A real shame
considering the potential applications for these boards.
Any suggestions on how this might be accomplished would be greatly
appreciated. Also, we will collaborate with any one working on the
same issue(s).

Does this mean that ICP power is always turned OFF in the NI board?

Data Acquisition Toolbox added IEPE accelerometer support for NI PCI-4461 and similar devices in R2011b. For a list of supported hardware go to http://mathworks.com/products/daq/supportedio.html

Was there any resolution to this? The response pointing to the matlab toolbox doesn't seem to address the specific problem of a power reset on start.
