Split Gate Set Up

Step 1:

The split gate is made to be used in combination with a two gate system.

Step 2:

Pair the gray “G” Split Gate pod with the gray “S” Start Gate pod. To do this, place the two pods side by side, and turn on. The lights will slow down and then begin to blink in sync.

Note: This system can allow up to four split gates. You only need to pair the “G” and “S” pod once, the pods will remember from then on.

Step 3

Set up pairs on tripods. You can have up to four split gates in a test station. The “G” gates automatically add a split time every time they are triggered. No need to make changes in Settings.

Tip: If one of the gray boxes is picking up stray light from the wrong black box, it may fail to detect a crossing. An easy way to determine if this is the case is to look at the gray box front LED, if its dark instead of blinking green, that tells you the gray box is picking up light from more than one black box.

To avoid stray light from one of the other gates (S or F), place the Split’s black box in the opposite side of the other two black boxes, you can also rotate the offending black box away from the Split gate.

Stray light can also come from reflections off walls or floors in small spaces or corridors. The infrared beam might bounce off walls or the floor in a hallway, bypassing the direct path between the black and gray boxes, which makes crossings hard to detect.
