Hello,

Mark, the AX301 is a different controller from Queensgate - an older
model I think. I've got the manuals for both controllers and the
communication protocols are unfortunately not related so I won't be able
to use the pzt.db stuff.

Kurt, if your code is for the NPS series controller then I'd be very
interested in having a closer look at it. The controller uses a funny
checksum calculation so I was already thinking about using SNL like you
have (instead of streamDevice).

Thanks,
Ulrik

Subject: Re: Queensgate NPS3*** series piezo controller

Hi Ulrik,

I wrote a simple, non- motor record application for this.  At the time
they (APS sec.3) just wanted to run one channel and were only able to
lend me the hardware for a short time.  So, what we ended up with is a
simple snl and database solution that met their needs, but not really
what I would consider complete device support.  You're welcome to what
we have, though.  If you are interested I will send it to you.
