NI-DAQmx driver error -200077
LausX
I'm testing my NI PCI-6503 Card and I get always this error:
NI-DAQmx driver error while calling function DAQmxCfgSampClkTiming;
device TTLBox:-200077: Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.
Extended info:
Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.
Property: DAQmx_SampTimingType
Requested Value: DAQmx_Val_SampClk
You Can Select: DAQmx_Val_OnDemand, DAQmx_Val_Handshake
Before, I send just this one command:
DAQmx_DIO_Config /DEV=deviceName/DIR=0/LGRP=0/Wave={testWave} "/TTLBox/port1"
Do you lknow how to solve this?
thanks a lot and merry christmas,
Not really...
I have spent about a half hour puzzling over the user manual for your device; it is somewhat complicated. What I have gleaned from it is that it is intended for handshaking I/O transfers, which means using the /HAND flag. I don't think simple clocked transfers are supported. You will have to read the manual (probably several times :) to learn how to connect all the handshaking signals. I think once you figure it all out you may be able to set up handshaking signals such that they work like simple clocked transfers. You may need an external source of pulses for the handshaking.
