The installer will configure everything, so do not worry about the pinout stuff, that is there in the manual just for your reference.
What you are describing, is that the board is seeing a servo fault. Which I think is normal as probably you have not tuned the servos yet. Set DIP4=off to disable servo fault detection to force the servo to remain active while you tune it. Once you have tuned the servos and they are OK, you can turn the servo fault detection again.

Got it. Pin17/Port2 relay is activating my 24vDC coil external relay. That is then sending the 24vDC to the Z-axis servo brake. It seems to be working correctly.

I know you said to use the C78 (RJ45 outputs) board for an external relay but this seems to work just fine. Only about .2 amps going through the Pin17/Port2 relay so I'd think that would have to be well within its capacity.

Thanks for your help.
