PCI-DDA04/12 Analog Output block
Simulink® Real-Time™ Library for Measurement Computing™
I/O Module Output
Block Input Data Type
Enter numbers between 1 and 4. 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 channels, enter
Number the channels beginning with 1 even if this board manufacturer starts numbering the channels with 0.
Enter a range code for each of the channels in the channel vector. The range vector must be the same length as the channel vector. This board allows the range of each channel to be different.
The following table is a list of the ranges for this driver and the corresponding range codes.
Input Range (V)
-10 to +10
-5 to +5
-2.5 to +2.5
0 to +10
0 to +5
0 to +2.5
For example, if the first channel is -10 to +10 volts and the second channel is 0 to +5 volts, enter
The range settings must correspond to the DIP switch settings on the board. Also the bipolar/unipolar jumpers must be placed according to the ranges used.
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
the corresponding channel is reset to the value specified in the initial
value vector. If you specify a value of
channel remains at the last value attained while the model was running.
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.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
If only one board of this type is in the target computer, enter
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
To determine the bus number and the PCI slot number, type:
