Q8 Analog Input block
Simulink® Real-Time™ Library for Quanser
Block Output Data Type
Enter a vector of numbers between 1 and 8. This driver allows you to enter channel numbers in arbitrary order. 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. Note that the input range is -10V to 10V for all channels and is not reconfigurable.
Two A/D chips on the Q8 board convert these channels. One A/D chip converts channels 1 to 4, the second A/D chip converts channels 5 to 8. To maximize throughput, balance the conversion load between the two groups of channels. For example, if you want to convert four channels, a channel vector value like the following has one A/D chip convert channels 1 and 2 and the other A/D chip convert channels 5 and 6:
[1, 2, 5, 6]
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
If only one board of this type is in the target computer, enter
locate the board.
If two or more boards of this type are in the target computer,
enter the bus number and the PCI slot number of the board associated
with this driver block. Use the format
To determine the bus number and the PCI slot number, type:
tg = slrt; getPCIInfo(tg, 'installed')
