how can i use the trigger of the umi 7774 to start the motion?

Giuan,

I don't think that there is a way to improve the synchronization. There is no way to do better than in the vi that you have attached. Using RTSI lines won't change anything.

Here is some brainstorming:
Ok, there is a trigger signal and you need to start your move with less than 1 ms relative to the trigger. There is no way to do this with the board so let's think about what else could we do with the trigger signal. We could use it for high speed capturing to capture the current position while the axis is moving. Does this help in any way? With a counter board we could measure the delay between the trigger signal and the first step being generated. Would this information help you?

There are a lot of more ideas in my mind but I don't know into which direction I should go from here. PLEASE! Give me the big picture of your application. What do you move? Which device generates the trigger? How and when is the trigger generated? Why is the limited delay so important?...

The more detailed information you give me the better I can help you.

Jochen
