7i77 analog wiring help

I'm sure this has been covered but I've searched without much success. I am wiring in a new machine and have one road block on the servo output control from TB5. Does anyone have a general wiring diagram for what connections are needed to the servo drives? I have been unable to match up anything that looks obvious.

I have attached an image of my drive input connections for CN3 input connector reference ! Any help is appreciated!

Most likely

7I77 AOUT(N) --> CN3.5 (AV-REF)
7I77 GND(N) --> CN3.6 (SIGNAL GND)

The 7I77 ENA(N) signals will likely connect between CN3.13 (DICOM) and CN3.14 (IN1)
(asssuming default input programming)

Not sure of the ENA polarity because its not indicated whether DICOM
is a positive or negative signal
