Question about AMT 103 encoder- Wire-X ????

[Jackal66]

I am connecting my AMT encoders up and looking at the cables.

They are:

Red- Connects to +5vdc on Gecko terminal #7

Black-Connects to encoder ground on Gecko terminal #6

Brown-Connects to CH-B on Gecko terminal #9

White-Connects to CH- A on Gecko terminal #8

Aqua-blue- called "X" on the encoder. There isn't a connection place for it on the Gecko diagram.

Is this what is called an indexer terminal?

Thanks,
Jackal

I don't see X, they use Z for the marker pulse?
Check: I see they also use X as index pulse.
I don't know why they use two different descriptions for the marker, confusing??
