[closed] Is Th and Tl the same as K+ K-

[Mcaughey]

On the diagram for upgrading the K40 to X7 there are three wires coming from the Laser PSU to the Controller
PSU >>>> X7
IN -- RED -- PWM -- Laser 1
GND -- GRN -- GDN -- Laser 1
TL -- YELLOW -- TTL --- Laser 1

I have two white wires coming off the Laser PSU that went to the Test button labelled K+ and K-. Is the K- the same as TL?

That is the only wire I was unsure about throughout the wiring, and the last one to hook up.

Apparently I got it right, everything seems to work.
