sync a repeater to an edp?

["Lance Chance" <lrc8918@louisiana.edu>]

hey fellas,
i've done this before and never i think that i even had to fight with this
particular issue, but when i try to sync my repeater to my edp, it won't
play or record.   it's like i'm sending a song stop message out of the edp
and i don't think that i am.   i know this is just something stupid that 
i'm
missing, but could someone give me a clue?
