Commands in Alphabetical Order
The following pages give details for each API command. Listed in alphabetical order, each section has a
table that summarizes the main features of the command (C, Visual BASIC, and Delphi language prototypes
and their related parameters). An explanation follows with related information and in some cases a
programming example. Typographic note: Commands, parameters, values, and code use a bold, mono-
spaced Courier font to help distinguish characters that can be ambiguous in other fonts.

Used With All devices
daqAdcArm allows you to arm an ADC acquisition by enabling the currently defined ADC
configuration for acquisition. ADC acquisition will occur when the trigger event (as specified by
daqAdcSetTrig)
is satisfied. All ADC acquisition configuration information must be specified
prior to the daqAdcArm command. For a previously configured acquisition, the daqAdcArm
command will use the specified parameters. If no previous configuration was given, or it is
desirable to change any or all acquisition parameters, then those commands relating to the desired
ADC acquisition configuration must be issued prior to calling daqAdcArm.
