Block Parameters

Channel vector

Enter a vector of numbers to specify the output channels. For example, to use the first and second analog output (D/A) channels enter

[1, 2]

The channel numbers can occur in arbitrary order. Number the channels beginning with 1 even if this board manufacturer numbers them beginning with 0. The maximum allowable channel number is 16.

Range

This board allows the range of each channel to be selected independently. Enter a scalar, in which case the same range is replicated over the analog output channel vector, or a vector the same length as the channel vector.

The range vector entries must be range codes selected from the following table:

Input Range (V)

Range Code

-10 to +10

-10

-5 to +5

-5

-2.5 to 2.5

-2

For example, if the first and second channel is -5 to +5 volts, enter [-5,-5]

Reset vector

The reset vector controls the behavior of the channel at model termination. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that setting is replicated over the channel vector. If you specify a value of 1, the corresponding channel is reset to the value specified in the initial value vector. If you specify a value of 0, the channel remains at the last value attained while the model was running.

Initial value vector

The initial value vector contains the initial voltage values for the output channels. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that value is replicated as the initial value over the channel vector. The channels are set to the initial values between the time the model is downloaded and the time it is started.

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')
