Attempting to send a trigger from one FlexRio FPGA device to anther along the PXIe-1085 back plane. I can see that NI-Sync has a software trigger but I want the trigger to come from the FPGA application because we need to make timing. I attempted to send the trigger by registering trigger 1-3 on bus 1 and registering trigger 4 on bus 2, which is where both my FlexRio devices are placed. I have routed the triggering and created a software panel from both my flexRio devices to send and recieve triggers but I am not seeing a reaction on either end. What is the best way to implement this and is there any examples of someone talking to two devices using triggering?

Can you upload the code you have so far? What modules are you using? Have you tried accessing the PXI_trig lines from an FPGA I/O node? Right click the IO node->Add new FPGA I/O->PXI-PXI_trig#->arrow to right->OK
