Function Usage
The daqSetOption function may be used to set options or configuration settings for a device, module or channel.
Generally, this function allows setting states or configuration information for a particular feature for a given device,
module or channel that cannot or should not be set using normal scan configuration settings.
When configuring options which relate to module or channel configurtions, this function should be called to set the
option prior to arming the acquisition (see daqAdcArm) . The device should have already been opened prior to
calling this function (see daqOpen) and the handle parameter indicates the device for which the option is to
apply.
The flags parameter indicates if the option applies to a channel or an entire channel bank according to the module
used. The flags parameter may be set to the following:
DcofChannel
-- Apply option to the channel specified by the chan parameter.
DcofModule
-- Apply option to the entire module for which chan is located.
The optionType specifies which option to apply. See the table in the “Parameter Type Definitions” section for a
complete description of valid option types.
The optionValue parameter specifies the value to set the option specfied by optionType (if applicable). See
the table in the “Parameter Type Definitions” section for more detailed description of the valid option values for the
desired option type.
