DAPL Input Configuration Commands

Input configuration commands define automatic data capture. Input sampling is characterized by the number and sequence of channels, timing, sample counts, and hardware triggering.

Input configuration commands are bracketed by special group delimiter command lines.

IDEFINE
Begin a group of commands that define an input sampling configuration.
END
End an input sampling configuration definition.

Configuration commands appear between the IDEFINE and END lines.

CHANNELS
Set the number if signals (or groups of signals) to be sampled by the input configuration.
SET
Establish the source and gain for a signal, assigning it to an internal data channel.
SCAN
Set the time interval for capturing a sample for every input channel.
TIME
Set a time interval between consecutive sampling operations.
COUNT
Set the number of samples to record before automatically terminating sampling.
HTRIGGER
Select a hardware trigger control mode.
CLOCK
Select a hardware sample clocking mode.
MASTER or SLAVE
Select a synchronization option for a multi-board system.

When the hardware features support it, some special processing can bypass the input sample clocking and poll input values directly from input hardware ports.

DIGITALIN
Bypass input clocking and observe the current input bits at a digital port.
