8 servo controller lights won't go off

I have a 8 servo controller, I give it power and all three lights come on.
I send it a stream of bytes from my serial port, and all three lights stay on and nothing happens.
I put a scope on the 10K resistor off of pin three and my signal was showing up being sent to that 10K resistor, but the servo doesn’t move and the lights stay on (constant).
I’m sending at 9600 baud.
I’m using four AA’s on com2.
And my serial cable is plugged into com3.
J1 jumper is off.

Any hints or help?
