Is it possible to configure a DIO-32HS with Level-ACK mode with NI-DAQmx 7.4? All that I see is "Handshake (8255... )" when I try to select a NI-DAQmx Timing.vi. If it is possible, how does one then set the ACK Delay?
Bernd
Use the DAQmx Timing (Handshaking).vi and these properties:
Try these settings:
For Input tasks:
| Property | Value |
| DAQmx Timing : Hshk.StartCond | Wait for Handshake trigger asserts |
| DAQmx Timing : Hshk.SampleInputDataWhen | Handshake Trigger Asserts |
| DAQmx Timing : Hshk.DelayAfterXfer | 100 ns |
| DAQmx Trigger : Hshk.Interlocked.AssertedLvl | High |
| DAQmx Export Signal : HshkEvent.OutputBehavior | Interlocked |
| DAQmx Export Signal : HshkEvent.Interlocked.Deassert Delay | 100 ns |
| DAQmx Export Signal : HshkEvent.Interlocked.AssertOnStart | T |
For Output tasks:
| Property | Value |
| DAQmx Timing : Hshk.StartCond | Immediate |
| DAQmx Timing : Hshk.DelayAfterXfer | 100 ns |
| DAQmx Trigger : Hshk.Interlocked.AssertedLvl | High |
| DAQmx Export Signal : HshkEvent.OutputBehavior | Interlocked |
| DAQmx Export Signal : HshkEvent.Interlocked.Deassert Delay | 100 ns |
| DAQmx Export Signal : HshkEvent.Interlocked.AssertOnStart | F |
You may need to lengthen the Deassert Delay to fit your device. You may need to change the polarity of the handshake trigger (Hshk.Interlocked.AssertedLvl) or the handshake event (HshkEvent.Interlocked.AssertOnStart)
