Driver block Parameter

Channel vector -- Enter numbers between 1 and 8. This driver allows the selection of individual channels in any order. The number of elements defines the number of A/D 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	Input Range (V)	Range Code
-10 to +10	-10	0 - 10	10
-5 to +5	-5	0 - 5	5

For example, if the first channel is -10 to + 10 volts and the second and fifth channels are 0 to +1 volts, enter

• [-10,1,1]
  

Sample time -- Model 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 jumper settings on the board. For example, if the base address is 300 (hexadecimal), enter

• 0x300
