Block Parameters

Channel vector

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]
Sample time

Enter the base sample time or a multiple of the base sample time (-1 means sample time is inherited).

PCI slot

If only one board of this type is in the target computer, enter -1 to 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 [BusNumber,SlotNumber]. To determine the bus number and the PCI slot number, type:

tg = slrt;
getPCIInfo(tg, 'installed')
