Driver Block Parameters

Channel vector -- Enter numbers between 1 and 16. This board allows the selection of individual A/D channels in any order. The number of elements defines the number of D/A channels used. 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 vector -- 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)
Range code
Input range (V)
Range code

-10 to +10
-10
0 - 10
10

-5 to +5
-5
0 - 5
5

-2.5 to +2.5
-2.5
0 to 2.5
2.5

Input range (V)	Range code	Input range (V)	Range code
-10 to +10	-10	0 - 10	10
-5 to +5	-5	0 - 5	5
-2.5 to +2.5	-2.5	0 to 2.5	2.5

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

```
[-10,5]
```

The range settings have to correspond to the DIP-switch settings 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 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 -- Base sample time of a multiple of the base sample time.

Base address - Enter the base address of the board. It is important that this entry corresponds to the DIP-switch settings on the board. For example, if the base address is 300 (hexadecimal), enter

```
0x300
```

The jumpers by the range DIP switches on the board all have to be in the XFER position. The Wait-State jumper has to be in the off position.
