Synchonisation of multipe different I/O modules inside a CompactDAQ Chassis

Hello,

I´m currently using various different I/O-modules (e.g. NI9229, NI9203) inside the cDAQ-9184 chassis.

For setting it up and creating tasks im using the NI MAX software. These tasks are then used in DASYLab 13.0.

The problem im experiencing is a constant time delay between signals from different I/O-modules. No matter what sample-rate type I´m using, there seems to be an issue with the synronisation between those modules. From my understandings, the chassis should synchronise the modules via internal clocks but with different tests I got a constant delay of 1.6ms between the same rising or falling edge, measured from different I/O-modules at the same time.

Is there something I got wrong or should the chassis indeed synchonise the signals on its own?

Thanks in advance!
