Wiring Pendant to MESA 7C80

Have this Pendant:
www.amazon.com/dp/B01E6VTZHC

Wiring as below (see attached image).


I have inputs 0-15 available on the 7c80 (have TB02.0 connected to GND)

Looks like Black, Black/white, Black/Orange can all be tied together and connected to GND
Black/Green and Red tied together and connected to 5v+ (power and LED+)
Yellow to an input pin (X)
Yellow/Black to an input pin (Y)
Brown to an input pin (Z)
Black/Brown to an input pin (4th)
Grey to an input pin (spd X1)
Black/Grey to an input pin (spd X10)
Orange to an input pin (spd X100)

I'm not sure on how to wire the A+,B+ and A-,B- for the dial

Looking at this post, would it make sense to use the Encoder (TB4) header for A/B?

Not sure on how i should wire the E-Stop, should E-Stop be controlling a relay for the psu/vfd input power (220v in this case)?

If Input common 0 (TB1 pin 1) is connected to +5V
You cannot use any signal other than 5V on inputs 0..11
 (so if you have +36 V signals, the common must be GND)

none of the signaling is 36v. I probably should have kept the E-Stop information more separated.

OK for 5V signals that should all work
On the differential MPG signals. I would just ignore the - pins

Note that inputs 0..7 are the MPG pins
