Generic Spindle interfaces, I/O boards, Misc boards and panels / ESS Estop active low, PMDX-126 Estop active High, how to overcome this?

Hi all,
ESS + PMDX-126 + PMDX 107, Mach4.
In the ESS Plugin ESS needs to have pin outs Estop, active low. The PMDX-126 Estop works active high.
In my understanding, for a start these should be on separate pin outs.(?)
The PMDX-126 Estop is port 1 pin 10.
Any other available input pin can be used for the ESS Estop signal.
I added a second switch to my Estop button so that two separate pins could handle the ESS Estop signal, and the PMDX-126 Estop signal.
Is it correct that the voltage for the pin chosen for the ESS has to be "sinked"? ("Sinked" according to section 13.0 PMDX-126c users manual, "low must be able to sink 6 mA at less than 0.8v")
And what is the best practice for executing this "sinked" voltage?
I see that now I am getting an Estop condition from the ESS when the button is not pressed, and an Estop condition from the PMDX-126 when the button is pressed.
Thank you in advance.
