Block Parameters

I/O format

Select serial or parallel. If you select serial, the block is configured to accept up to 32 one-bit input channels for output. If you select parallel, the block is configured to accept a single 32-bit channel and the channel vector parameter is unavailable.

Channel vector

For serial I/O format, enter a vector of numbers to specify the output channels. For example, to use the first and third digital output channels, enter

[1, 3]

The channel numbers can occur in arbitrary order, but the numbers must be in the range 1 to 32.

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 (0 or 1) 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. If you selected parallel I/O format, the values can be in the form [hex2dec('ffffffff')].

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')
