GPS mode with shack clock

With the clock and QLG2 SE module what GPS mode is correct ?  Options are 0, 1, or 2.  I'm assuming it should be 1 but would appreciate the experience of this group.

Thanks for your replies

I'm using #2 which the clock manual states the mode that is "most appropriate" for the GPS 1pps 100ms pulse width. I have no idea the pulse width of the QLG2 SE, but it works FB with the clock kit....which by the way I love!
