Driver Block Parameters

Channel vector -- Enter numbers between 1 and 4. This driver allows the selection of individual D/A channels in any 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 the board manufacturer starts numbering the channels with 0

Range -- From the list, choose a range code. This driver does not allows a different range for each or the 4 channels. This selection has to correspond to the range and bipolar/unipolar jumper settings on the board.

The following table is a list of the ranges for this driver and the corresponding range codes. The D/A specific jumpers on the board have to be in the correct positions for the ranges entered.

Input Range (V)
Range Code
Input Range (V)
Range Code

-10 to +10
-10
0 to +10
10

-5 to +5
-5
0 to +5
5

Input Range (V)	Range Code	Input Range (V)	Range Code
-10 to +10	-10	0 to +10	10
-5 to +5	-5	0 to +5	5

For example, if the first channel is 0 to + 10 volts and the second channel is 0 to +5 volts, enter

```
[10,5]
```

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 used for all channels. 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 the initial value for all channels. 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.

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

```
0x300
```
