password for rayview app connection

Hello

I am trying to interface a new ES127nwith Ray view Control. When I go to wireless settings on the ipad i find my MFD wireless connection. If I try to join it wants a password. I dont remember setting up a password for the Ray View app or seeing a password to be used when connecting to the MfD. If there a standard password or a place that it is located so i can connect to the MFD?
