Please don't tell me that I need *2* of these boxes?

I want to take my repeater at a building downtown and *remote* it to my allstar box at my house.  I think I only need one RTCM to do that… however, now that I have it configured and pointed at my allstar server, it keeps complaining that it can't set it's time and as a result, it won't connect?

So, what configuration do I need to change to make this work?

Thanks in advance,

Alan
