Thanks guys, that’s good to know
FYI, below is what I was referring to, maybe it applies to the initial setup?
From Humminbird’s 360 Imaging for Helix Operations Guide:
“POWER ON AND CONFIRM CONNECTIONS
All equipment should be connected and powered before you turn on the control head.
CAUTION! It is important to finish all installation connections before powering on the control head. It may take up to a minute for the 360 Imaging transducer and other attached equipment to be detected by the control head.
1. Turnonthepowersourcefromthemainswitch.
2. Onthecontrolhead,pressthe POWERkey.
If you are powering on a control head in a multiple-control head Ethernet network, power on the control head that is connected to the 360 Imaging transducer first.”
