Hello all. 

I've connected a Lightware SF10/c to my pixhawk serial 4/5 port as the instructions here show:http://copter.ardupilot.com/wiki/com...re-sf10-lidar/

My SonarRange is flat on 0. I can see that the unit is powered up because I can see the dot on the floor with a digital camera. I've triple checked continuity of the cable I made and I also (using the cable I made for the Pixhawk) with small jumpers stuck in the little connector, attached it to a USB to Serial adapter and with Putty I can see the distance just fine.

I dropped it down to 9600 baud, still nothing.

I'm new to pixhawk/apm world so I'm not really sure how to troubleshoot. I've double checked the wiring.

I currently am running firmware 3.3.2.

Lastly, this is still not done being built. This is my first experience with a Pixhawk. I'm upgrading from an Eagle Tree Vector. I'm not done rewiring. I am still waiting for a power module because I refuse to use the little 90A one that was supplied by 3DR. 

Thank you all.
