Marantz receiver driver (IP)

[dlmorgan999]

I just got a new Marantz receiver and am trying to get it working via IP.  It's not one of the models listed, but in looking at the protocol, it seems that at least the basics should work.

The issue I'm running into is one that was reported in the past.  I'm stuck at "Wait for connect".  I put in in verbose mode, and the error I'm seeing is this:

Code:

05/13 18:06:30-CQC-MASTER, CQCServer, CQCDrv_marantzThread17444
{
    CQCGenDrvS, MEng.System.CQC.Drivers.Marantz.AV8801.DriverImpl.1162, Status/App Status
    Exception in connect. Err=Timed out waiting for a message
}

I believe this is the same issue that was occurring in the past.  Any ideas / suggestions, or am I out of luck?
