Pixhawk connected to an AR7700

[jeffw58]

Has anyone connected an Spektrum AR7700 serial receiver to a Pixhawk?
I am interested in connecting it using the Remote Receiver or SRXL ports.
Where would you connect the AR7700 Remote Receiver port to the Pixhawk?
Where would you connect the AR7700 SRXL port to the Pixhawk?
Horizon Hobby states both ports are compatible with the Pixhawk but they don't give any examples.
I am assuming SRXL is the faster more preferred option.

Thanks for your help!

Here is a picture of the cable I built to connect the AR7700 to the Pixhawk through the SPKT port.
