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.
- Begin a group of commands that define an input sampling configuration.
- End an input sampling configuration definition.
Configuration commands appear between the
- Set the number if signals (or groups of signals) to be sampled by the input configuration.
- Establish the source and gain for a signal, assigning it to an internal data channel.
- Set the time interval for capturing a sample for every input channel.
- Set a time interval between consecutive sampling operations.
- Set the number of samples to record before automatically terminating sampling.
- Select a hardware trigger control mode.
- Select a hardware sample clocking mode.
- 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.
- Bypass input clocking and observe the current input bits at a digital port.
