Block Parameters

Channel vector

If you select 16 channels (Input coupling parameter set to Single-ended), enter numbers between 1 and 16. If you select differential (Input coupling parameter set to differential), enter numbers between 1 and 8. For example, to use the first and second analog output (A/D) channels, enter

[1,2]

Number the channels beginning with 1 even if this board manufacturer starts to number 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 board allows the range of each channel to be different.

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

Input Range (V)

Range Code

-10 to +10

-10

-5 to +5

-5

-2.5 to +2.5

-2.5

-1.25 to +1.25

-1.25

-0.625 to +0.625

-0.625

0 to 10

0 to +2.5

2.5

0 to +1.25

1.25

For example, if the first channel is -10 to +10 volts and the second channel is 0 to +5 volts, enter

[-10,5]

The range settings must correspond to the DIP switch settings on the board.

Input coupling

From the list, select one from the following list of input modes:

  • Single-ended channels (16 channels)

  • differential channels (8 channels)

This choice must correspond to the MUX switch setting on the board.

Sample time

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

Base address

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 0x300.
