====== ScanImage 3.7 ======
Some notes about our tests of the 3.7 series which foundered on a problem talking to the Sutter MP285 controller.

Hi Greg, That is very disappointing to hear. There was a bug prior to 3558
that was leading to unreasonably frequent motor communication
failures...that's been fixed in r3558.
At the moment , r3.7/r3558 has been working reliably with the MP-285 in our
hands. I remember seeing a startup connection issue like the one you describe,
but this was before the bugfix and with someone who was using 2009b, which was
fixed by going to 2010b. As far as we know, that bug was the main source of
MP-285 failures.
We are working on further improving the motor interface with the aim of
making it even more reliable in our hands, as part of 3.8, i.e. to squeeze out
rarer events leading to failure. But certainly we're not seeing issues to
level you describe with r3.7.
I'm not sure how much I can help further without really being at your machine
to try and see if there's some timing difference, etc. leading to the problem.
The best I can do I think is send on 3.8 when we've finished the motor changes
there. (In general, I was only going to suggest 3.8 to new users or users
interested in Cycle mode.)
Best regards Vijay

Hi Vijay,
This is the description of an MP-285 controller problem that we were having
with 3.7 both release and even worse r3558. We are using 2010b SP1 with 3.7
series and 2008b with 3.6.
We're using an MP285 controller as delivered to us by Sutter with a MOM unit
in April 2010. with the release 3.7 scanimage would establish communication
but then frequently have dropped connections. With this r3558 version
scanimage is failing to establish communication at all. We can talk to the
MP285 with scanimage 3.6 or a terminal session, so I suspect a code change. We
are using defaults only for the controller apart from specifying in the ini
file that it is an mp285. Does this ring a bell?
We see no improvement in this behaviour between r3558 and 3.7.1 beta. Did you
chaps think that you had found a fix or is this one outstanding?
Many thanks,
Greg.
====== ScanImage 3.8rc1 ======

Aaron testing this with Matlab 2010b SP1
After moving ''C:\Program Files\ScanImage\SCANIMAGE_r3.8RC1.new\+dabs\+ni\+daqmx\private\NIDAQmx_8_8\NIDAQmx.h'' to the private folder, fixed one error message bust still get. DLL C:\windows\system32\nicaiu.dll does not seem to be present.

===== Second Attempt Feb 2012 =====
* Had to clone hard drive onto new drive provided by IT
* Had to upgrade NIDAQmx to 9.3
* Had to switch licensing of matlab to MAC address rather than disk serial number
* By deactivating on website
* reactivating and giving it the mac address as hostid
* downloading a license file a
* and choosing manual activation and pointing matlab to said license file
* Had to install 64 bit matlab (but not data acquisition toolbox, which is no longer required)
This time we get an error related to MP285 controller

After specifying the MO285 properties in the standard.ini file, we git this error (likely because it was the next time itried to talk to the MP285)

This smells like the same problem with the MP285 that killed our attempts to run 3.7.1. We can talk to the controller fine with a putty serial connection. The comms settings match what is in the standard.ini. The controller has a very old firmware (2001) but the version WD3.4 seems to match the recommendation from the ScanImage wiki.
