Description
daqSetOption allows the setting of options for a device's channel/signal path configuration.
chan specifies which channel the option applies to.
flags parameter specifies how the option is to be applied.
optionType specifies the type of option to apply to the channel.
optionValue parameter specifies the value of the option.
Note: For more information regarding optionValue and optionType refer to page B-32, Table 8.
Note: The following information does not apply to Personal Daq/54.
daqSetOption must be used to properly configure Personal Daq's frequency input and pulse count channels. To configure frequency input
and pulse count channels, the following option types need to be specified for each frequency input/pulse count channel in the scan
sequence:
DcotpDaqPulses: Configures the specified channel as a pulse count channel.
DcotpDaqRising: Configures the rising flag for the pulse channel.
DcotpDaqDebounceTime: Configures the debounce time for the frequency/pulse channel.
The following options must also be specified to configure frequency input channels:
DcotpDaqMinFreq: Configures the minimum frequency range for the specified channel.
DcotpDaqMaxFreq: Configures the maximum frequency range for the specified channel.
DcotpDaqFreqRes: Configures the resolution of the specified frequency channel.
DcotpDaqOverrangeProtect: Enables the overrange protection mode.

Description
daqSetTimeout allows you to set the time-out for waiting on a single event or multiple events. This function can be used in conjunction
with the daqWaitForEvent and daqWaitForEvents functions to specify a maximum amount of time to wait for the event(s) to be
satisfied.
The mSecTimeout parameter specifies the maximum amount of time (in milliseconds) to wait for the event(s) to occur. If the event(s) do
not occur within the specified time-out, the daqWaitForEvent and/or daqWaitForEvents will return.
