Hello all
I am facing some problems while synchronizing four PCI-6123 DAQs. Currently i am using Measurement and automation Explorer software. I need four DAQs to acquire 32 analog channels simultaneously. From NI-DAQmx Devices, i selected RTSI Cable and add four NI PCI-6123 devices to it. Then From NI-DAQmx Task, i created a task to acquire analog signals from all available channels.
I tried all Trigger Type and Trigger source options but when I want to see connection diagram, following error occurs:
Error -200262 occurred at DAQ Assistant
Possible Reason(s):
Measurements: An attempt has been made to configure a trigger without
configuring the appropriate sample clock properties or when Sample Timing Type
was set to On Demand.
Configure the sample clock type to something other than On Demand to use a
trigger.
Property: Start.TrigType
Corresponding Value: Digital Edge
Property: SampTimingType
Corresponding Value: On Demand
I know I am missing something. Kindly help me.
Best Regards
ASIM

Hi Asim,
Make sure you have included all your devices in your RTSI device in Measurement & Automation Explorer (MAX). This should enable you to put all AI in a single task, and the synchronizing will be done by DAQmx.
