I got a sling box 500 over the weekend and attempted to hook it up with little success, tried HDMI friday and I am assuming it is HDCP protected as I got nothing to appear using the sling box for desktop app (using windows 10), connecting it through composite cable (this model of cable tv box only has HDMI, composite, and COAX) I was able to get a picture, but I am unable to change the channel using the desktop app because as far as I know the sling box only supports IR blast for channel changing, and the PACE PX022ANX box only has RF in the menu. It's possible that I am missing a setting somewhere on the cable box that would allow it to switch to IR from RF, or use both at the same time. Has anybody been successful in connecting a sling box to the PACE PX022ANX?
Thanks for any help/advice!
First, yes, the cable box uses HDCP. HDMI won't work.
As for the RF input for the remote, AFAIK IR should also work in conjunction with RF, as per here. User jchasen said;
"... I just had three Contour 2 boxes installed and was easily able to program my Universal Remote Control MX-850 remotes and my MX-980 to control the boxes (via RF base stations hooked to IR emitters). If you need to program a universal remote just look for codes that are meant to support Comcast Xfinity boxes..."
If none of the Comcast codes work during setup, you can always upload .bin files, but that would require some kind of IR scanning/learning device. See here for more info.
Thank you very much for the information, I will have to dig into it more when I get off work.
The short of it is to try Comcast cable box codes, not Cox. I say codes, but I mean the drop down in the picture below.
You are awesome, thanks again for the info.
