Directv receiver installation

[Mel41]

Does anyone know how to install a directv reciever. We have a Jayco Seneca. We have a main TV, one outside, and one in the bedroom. They all connected to a CONNEX HDMI UTP MATRIX. The satellite dish is a Winegard Roadtrip. We have connected the reciever via a HDMI cable to the connex but it doesn’t appear to be coming through the TV. Any ideas? Thank you.

We called Winegard customer support - they walked us thru the install with the Direct Box we purchased.

Mel41, did find out anything from Winegard? Just bought a 2018 Seneca, plugged in my Directv HD receiver to the Connect, and no picture. then plugged into the hdmi slot where the DVD was plugged into, and go a picture from the Directv receiver.
No trying to figure how to get the DVD to work on the other ports. Tried switched manually and with remote, but no success.
