Block Input Data Type





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 arbitrary order. The number of elements defines the number of D/A channels used.

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


Number the channels beginning with 1 even if this 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


0 to +10


0 to +5


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

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.
