Two ways of specifying 6602 DMA transfer?

[DarrenJones]

I have previously used "Counter Set Attribute.vi" to set the transfer method attribute to DMA for individual counters on the PCI-6602 board. I've noticed that an example from NI uses another method: "Set DAQ Device Information.vi" is used to set the information type 'data transfer mode for GPCTR [XX]' to 'up to 1 DMA channel'. Is there a difference between these two? If so, is there an advantage to using one over the other?

thanks.

There should be no differences between using one or ther other command. They will set the same flags to setup that counter to use DMA for transfer instead of Interrupts.
