DASYLab Limitations?

[mattwells]

Good Morning, I am using an MCCDAQ USB-2527 Control Board in conjunction with DASYLAB Full V.10. 

I selected this board on the basis of the specifications advertised by Measurement Computing; synchronous A/D, D/A, DIO w/1MS/s throughput.  This board has on-board clock for timing both the analog and digital operations.  DASYLab was selected because of the advertised compatibility with M.Computing products and the percieved simplicity for system prototyping.

According to the board specifications I should be able to send digital commands at a frequency of up to 4MHz maximum (I need far less than this), synchronous with input scannin, and with the option of pacing using the onboard scan clock.  Within DASYLab I attempt to configure my board to do hardware pacing for the digital I/O and cannot.  Furthermore, accepting PCClock/DASYlab as my pacer (and the variability in the frequency and hold time of a square wave (0-5V) that this causes) I struggle to get more than 1-2 Hz output.

I guess the crux of my question is as follows:  is DASYLab inherently limited in the amount of functionality it can exercise on an MCC DAQ board?  Do I require hard-coding to get full board functionality?  Is there a way to set synchronous DIO with hardware timing in DASYLa?  Is there a hack?

Thanks,
Matt Wells

I have recently been informed by Adept Scientific that Dasylab is limited to 2.8 mHz which is a little disappointing because I am looking for synchronous sampling on 2 channels at up to 4 mHz and up to 1 mHz on another 5 channels.

For hardware specific support issues, such as this, you should contact your reseller directly. Whether it's Measurement Computing directly, or one of their resellers, they will have the most accurate information to assist you! They will be able to advise you of the DASYLab compatibility with any of their hardware.
