PD2-AO Analog Output block

I/O Module Output
Block Input Data Type
Select the specific board type from the list provided.
Enter a vector of numbers to specify the output channels between 1 and 8, 1 and 16, 1 and 32, or 1 and 96. For example, to use the first and second analog output (D/A) channels, enter
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 for PD2-AO series boards is 8, 16, 32, or 96 depending on the specific board type.
Note, the UEI PD2-AO 96 channel board only works if you specify a contiguous group of channels. These channels also must be listed in order. If you enter a non-contiguous channel list in the Channel vector parameter, the board does not produce output.
As a workaround, enter a contiguous specification like:
[1 2 3 4 5]
to use channels 1, 3, and 5. Connect a Simulink ground to channels 2 and 4.
The reset vector must be the same length as the channel vector. It contains values of 0 or 1. This parameter controls the behavior at model termination. A value of 1 causes the corresponding channel to be reset to the value specified in the initial value vector. A value of 0 causes the channel to remain at the last value attained while the model was running.
If your board is the 96 channel version, the board reads only
the first value in the vector and resets the channels according to
that first value. For example, if the first value of the vector is
the board resets all
96 channels to the values specified in the Initial value
The initial value vector must be the same length as the channel vector and should contain the initial voltage values for the output channels. The channels are set to these 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:
tg = slrt; getPCIInfo(tg, 'installed')
