Hello,
It's true that the 6723 does not support the Arm Start Trigger (it uses the same underlying counter architecture as E Series if anybody is interested). However, these devices still support using a regular "Start trigger" so you should still be able to do what you want.
On hardware that supports it, the arm start is a dedicated line that can be used to enable the counter. On supported hardware, counter output tasks allow for both an arm start and a start trigger--the start trigger begins the output but will be ignored if the arm start has not yet been received. If you don't have a start trigger configured but you do have an arm start trigger configured, the effect is that the output will start immediately once the counter is armed (so the arm start and start trigger behave similarly if only one is configured).
Arm start triggers are more typically used for counter input tasks when you want to have control over when the counter actually starts counting (counter input tasks do not support the regular start trigger).
So, if you see reference to something that includes an Arm Start trigger applied to counter output task, in many cases you can get the same behavior using the regular start trigger instead (which is supported on your hardware). In your case, you can either implement a retriggerable single pulse to be triggered off of the continuous output of the other counter (would let you vary the delay on-the-fly), or you could configure two continuous counter outputs with the same trigger (or trigger one off of the other) but different initial delays (one counter output would end up with a pre-determined user-configurable delay relative to the other).
