Driver Block Parameters

Channel Vector - Enter numbers between 1 and 16. This driver allows you to

enter channel numbers in any order.

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 in the channel

vector. The range vector must be the same length as the channel vector. This

driver allows each channel to be different.

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

range codes.

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]

Coupling Vector - Enter a coupling code for each of the channels in the

channel vector. The coupling vector must be the same length as the channel

vector. This driver allows a different coupling for each channel.
