Help require with skybox V8 and openbox V8

I just recieve my 2x boxes

sky box v8
openbox v8

I have turn on sky box and under network I dod not see any camd option. I have tried to press 0000, 6666, 8888 but no joy.

I have never use these boxes ever before so I have no clue whats so ever what are they.

I tried to reade on google and more I read more I confuse.
People brick them, then recover them then reflash them etc........

I do not know do I need to flash with any preticular firmware before camd set up ?

can these boxes be conecct via telnet ? can I ftp them to add cccam.cfg ? I see people update via usb.

I have good experience with dreambox, vu boxes but these are seems HARD to me to understand.

can some one please guide me through once instead give me a link to read.

Looking forword some expert help.

Thanks
