Block Parameters

Channel vector

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 you use. 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.

Range

From the list, select 0 to 5V or -5V to 5V as the input voltage range of the board. The input range applies to all channels.

This choice must correspond to the jumper setting in block J5 on the board.

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 input 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 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 provide an out-of-range value for a channel, that value is adjusted to be within the range defined by the parameter Range.

Sample time

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

Base address

Enter the base address of the board. This entry must correspond to the DIP switch setting on the board. For example, if the DIP switch setting is 300 (hexadecimal), enter 0x300.
