PCL-812 Analog Output (D/A)

Scaling of Input to Output

Hardware Output	Block Input Data Type	Scaling
volts	double	1

Driver Block Parameter

Channel vector -- Enter numbers between 1 and 2. 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 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	Range code	Input range	Range code
0 to +5V	5

For example, if both channels are 0 to +5 volts, enter

• [5,5]
  

The range settings have to correspond to the DIP-switch settings on the board.

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
