Hi Guys, my ping 360 works fine, except for the dropout which sometimes can happen in ten minutes, or sometimes as short as two or three minutes. Restarting Pingviewer shows message ’ No devices detected’. I tried manual connection, every combination available, still no go. I can get the display on screen but no scanning. The only way to get it up and running again is to disconnect and reconnect the sub battery.  
Any ideas / guidance ?
