Thanks Guy and Mark
Unfortunately I have no cable here for the remote audio output of the ts480, but this is in fact not a tragedy. Yes, I have a laptop, but what should I test with it? I can ping the fixed IP of the remote PC, switch off and on the ts480 via HRD and control the remote PC via TeamViewer, but this is not sufficient, what I need is to be 100% sure that all connections of the boxes are OK when I return to my QTH.
But this is also not so tragic if I can control the remote PC and router from the local QTH, I hope....
