SKY Super Plus HD Mexico

Here in Mexico SKY Introduce recently the HR44 with client MC-41, very similar to DirectTV c-41. My HR44 is working so good, but I can not see my client equipments. I reviewed some similar topics and I know that I have to set an external option in the main equipment. It is on. But when I try to discover my equipments I just see my HR44.

with some network scanner I can see the IP of the client, but if I set manually It doesn’t recognize it.

I hope you can help me, very nice products and services

Regards from Mexico.
