Trig

Postby grahamblackwell » Sat Jun 07, 2008 12:36 pm

So do I pull TRIG down to ground to signify that I'm at the start line, with the unit already logging, or does TRIG to ground do the same thing as pressing the red log button on the front of the DL1?

ie I'd like to have the DL1 running, and press a button to signify I'm ready to go and waiting at the start line.

There are two inputs that have different functions:

Lap Beacon Input Triggering voltage requires a low input of <1v and a high input of >4v and 15v maximum.

Start Sample Input Input requires grounding to start sampling and again to stop sampling.
