RC Input Spits Out 0

I am using a Hobby King HK-T4A V2: http://www.hobbyking.com/hobbyking/store/__8338__Hobby_King_2_4Ghz_4Ch_Tx_Rx_V2_Mode_2_.html

I connect CH1 from the receiver to the RC Input. When I connect to mission planner and go to radio calibration, nothing changes. I also went to the example scripts and ran the python and cpp RCInput code, but only got 0 as outputs.

Is there something I am missing??

It seems like this receiver does not have PPM output.

Thank you. I will look into getting another one.
