Is the SF11/C compatible with Pixhawk 2.1? And how do you connect them?

I am looking to use the SF11/C laser altimeter with the Pixhawk 2.1 and was just checking if it was possible? And if it is, does anyone have details on connection? Thanks!

Yes, the SF11/C is fully compatible with the Pixhawk 2.1. For connection and setup you can refer to: LightWare SF10 and SF11 Lidar — Copter documentation

The connection for Pixhawk 2.1 is very similar to that of the original Pixhawk but instead of connecting to serial4/5 port, you connect it to the GPS2 port of the Pixhawk 2.1.
