Block Parameters

Channel vector

Enter numbers between 1 and 8 to select the analog output (D/A) channels used. This driver allows the selection of individual channels in any order. The number of elements defines the number of D/A channels used.

For example, to use the first, second, and fifth channels, enter

[1,2,5]

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 entered in the channel vector. The range vector must be the same length as the channel vector. This driver allows a different range for each channel.

The following table is a list of the ranges for this driver and the corresponding range codes.

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

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

[10,5,5]

Sample time

Enter the model base sample time or 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
