Board ID (0) Specifies the ADAC-LVi board ID number to be used in this acquisition.
The ID numbers are defined in the configuration file ADAC-LVi.con located in the
Windows main directory.

Channel List (0(1)) Channel List is a string that specifies the analog input channel
number(s) to acquire data from.

For boards that support input gain the channel list also specifies a separate gain value for
each channel. Gains are specified in parentheses after the channel number. For example,
"0(1),1(8),2(4)" is interpreted as channel 0 at a gain of 1, channel 1 at a gain of 8 and
channel 2 at a gain of 4.

Cycle Mode (Single:0) Cycle Mode is a numeric value that sets the software cycle
operation mode. Data can be collected in a single scan (SINGLE_CYCLE) filling buffer
0-n and then stopping acquisition or collected continuously (CONTINUOUS_CYCLE)
filling buffers 0-n repeatedly. The available options are:

0:SINGLE_CYCLE Complete acquisition scan of 0-n buffers and stop. Supported by all
A/D's.

1:CONTINUOUS_CYCLE Restart acquisition, repeatedly loop on 0-n buffers.
Supported by A/Ds with DMA, Interrupt or FIFO capabilities.

For CONTINUOUS_CYCLE the Clock Source can not be set to
SOFTWARE_CONVERT or an
error will be generated immediately.

The default Cycle Mode is 0:SINGLE_CYCLE.
