Block Parameters

Channel vector

Enter numbers between 1 and 32. Channels 1-16 refer to the voltage output channels, and 17-32 the current output channels. This driver allows the selection of individual D/A channels in arbitrary order. The number of elements defines the number of D/A channels used. For example, to use the first and second analog output (D/A) channels, enter

[1,2]

Number the channels beginning with 1 even if this board manufacturer starts numbering the channels with 0.

Sample time

Enter the base sample time or a multiple of the base sample time (-1 means sample time is inherited).

PCI slot (-1:autosearch)

If only one board of this type is in the target computer, enter -1 to locate the board.

If two or more boards of this type are in the target computer, enter the bus number and the PCI slot number of the board associated with this driver block. Use the format [BusNumber,SlotNumber].

To determine the bus number and the PCI slot number, type:

tg = slrt;
getPCIInfo(tg, 'installed')
