Synchronize two 6551s using TCLK

Hi there,
 
I'm trying to synchronize two 6551 devices using TCLK, but im getting (at least to me) rather strange errors. This is the way, I'm intending to realize it:
Each 6551 is configured 10 pins analyzer / 10 pins generator with hardware compare.
The acquisition sessions are to be started via software, the strobing of the data is achieved by the strobe signal from the DUT board. The source for this is the data active event from the generation session.
The error occurs when executing niTCLK synchronize.vi. It returns with error -250033 caused by an underlying DAQmx error telling me that TCLK tries to route the Data Active event from one of the 6551s to PXI_Trig0; a route that is not possible with the 6551.
 
Any ideas?
 
Cheers
Oli

Hi all,

problem is solved... there was some other piece of code in the background that conflicted with TCLK.

Cheers
