1 small clarification to your very informative post ...

Any HB Ethernet capable unit can share any external (or internal) GPS antenna on the network ...

HELIX Ethernet capable units cannot share heading separate from GPS from an external heading sensor/GPS puck like HDS, ONIX, or SOLIX ...

HELIX must share both heading and GPS from the external puck ...
