Automation Direct sureservo2 enable / 7i77

I'm replacing my servos with AD SureServo2 motors and drivers.
I'm struggling to get the enable to work correctly.

The manual shows this
 

Pin 30 (DI8) is the input pin for the enable.

Pin 11 can take 24V or 0V as noted in this chart.
 

I've tried several combinations that seemed intuitive to me but no success.  Can someone advise on the 'right' way to do this?

Assuming drive COM+ is +24V,

7I77 ENA+ to  Drive DI
7I77 ENA- 24V supply negative side
