crio not communicating with digital io module/sidecar

[stcywlkr]

I cannot seem to get the crio to communicate with my digital io module, the blinking light on the sidecar representing the communication from digital i/o module is not blinking. Also, when I set a relay to forward or reverse, light for relay does not turn green or red. At a loss, any help would be greatly appreciated. I am able to control motors using jaquars and pwm but that is analog and going through a different card. Is there anything special that needs to happen to configure the digital io module/card. I have it in slot 2 of the crio.
