7i84 output wiring

Hi 
I am having some issues setting up my 7i84 connected to 7i96s .
i can't figure out the inputs and outputs on the 7i84.
The 7i96 is easy as it has 2 pins per IO
THe 7i84 having only the one from my understanding I need to ground or have set to 24v. Pending my card model.
I have got the tb1 pins set to 24v and have checked polarity.
I am trying to use the output to drive a relay. However when checking the output after it is activated on HAL I can't get it to function when tested with a multi meter. I have also tried connecting the other side of the relay to both ground and 24v and cannot get the relay to trigger.
For inputs they all measure at 24v
Any ideas? Or pointers for what I'm doing wrong?

Thanks for the information.
The Red LED I was a bit suspect on so will need to do some looking into this could this potentially be a configuration issue in LCNC?
So as I have the 7I84D it is sinking and when active as a test I should have continuance between ground and the pin.
Will have another read over the manual.

Unless you have a blinking green on the 7I84/7I84D
there is no communication with LinuxCNC so all
outputs will be off

Thanks everyone.
I got it to work, there were 2 issues at play.
1 I did not have power hooked up to the logic power pin 5.
2. In the config I was using mode 3 as mode 1 would not allow LCNC to open with no power as above.
Now I can continue my wiring now I have all of that functioning!
