Block Output Data Type
Enter numbers between 1 and 16. This driver allows the selection of individual A/D channels in arbitrary order. The number of elements defines the number of A/D channels used.
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.
8 for each of the channels in the channel vector
to choose the gain code of that channel. The gain vector must be the
same length as the channel vector. This driver allows the gain of
each channel to be different.
The following table is a list of the ranges for this driver given the gain entered in the gain vector.
-10 to 10
-5 to +5
-2.5 to 2.5
-1.25 to 1.25
Notice that by increasing the gain code the voltage range is decreased. The gain divides the input voltage range.
For example, if the first channel has a gain code of 1 (10 volt range) and the second and fifth channels have a gain code of 2 (5 volt range), enter
Enter either 1 (single-ended) or 2 (differential) for each of the channels in the channel vector to choose the coupling code. The coupling vector must be the same length as the channel vector. This driver allows the coupling of each channel to be different.
For example, if the first and second channels are single-ended and the fifth channel is a differential input, enter
The driver selects a second differential input 8 channels higher than the first channel. In the example above, the driver would select the thirteenth channel as a differential input with the fifth channel.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
Enter the base address of the board. This entry must correspond
to the DIP switch setting on the board. For example, if the DIP switch
setting is 300 (hexadecimal), enter
