no more SC-2040 in DAQMX 8. 1 ??

[josswern]

hello all,
I'm currently in a process to port my daq software (lw-cvi) to DAQMX (formerly: traditional NI-DAQ) and had already finished some parts,
but still problems.
so I decided to upgrade to DAQMX 8.1, but now, I noticed, that the SC-2040 S/H amplifier which I used for simultaneous scanning with
E-series boards, seems no longer available in MAX 4.0.3 (from DAQMX 8.1) as an accessory for my new M-series board (PCI-6250).
anyone knows what's going on here ?
thanks.

The SC-2040 didn't work properly in NI-DAQmx 8.0 when only configured in MAX. The PCI-6143 simultaneously sampling DAQ board is a much better choice than a combination of an M-Series board and a SC-2040 so the decision was made to remove it from the list of  accessories in NI-DAQmx 8.1

Still it's possible to work with the SC-2040 and an M-Series board with NI-DAQmx 8.1. Instead of configuring the SC-2040 as an accessory you can add some function calls to your code to export and configure the necessary timing signals for the board.

ok,
thanks for the hints - as for the article in the knowledgebase, I had already got this advice from my local NI support.
anyways, it is now much clearer to me why the sc2040 was still available as accessory in MAX from daqmx 8.0.1, but not any more in daqmx 8.1.
I will also consider the pci6143 for future applications, but first I will try to get our existing sc2040's to work with m-series boards.
