XNET and DAQ cards RTSI synchronisation using frame queued sessions

XNET and DAQ cards RTSI synchronisation using frame queued sessions

‎09-11-2020 03:41 AM

Hello the forum,

on a PC equipped with a PCI-8512 and a PCI-6229 cards connected with a RTSI cable, I developed a driver able to exchange data with a device on a CAN bus and acquire some input signals. The synchronisation between the two cards is set during initialization using the Connect Terminals VI, as shown in the following picture.

I had then to change the global approach and to switch to the use of several frame queued sessions.

My question is: using the Connect Terminal VI on the first read frame session only, is it enough to grant the synchronisation between the two cards for all the other read frames?

 

Thanks
