Lowrance electronic HDS SERIES Manual Do Utilizador

The HDS system uses an Ethernet network to interconnect high bandwidth devices such as 

other HDS displays, radar and sonar. Each HDS display has one network port with 5 pin 

connector. Ethernet network has orange connectors that are retained by a bayonet type locking 

collar.

If more than two network devices need to be connected, use the optional Network  Expansion 

Port (NEP). which will allow for the connection of up to five ethernet devices or a 

StructureScan module which will allow for the connection of up to three ethernet devices.

The Ethernet connection carries sonar, Structurescan and radar data between two or more 

displays. Sonar data (water,speed, depth and temperature) is bridged onto the Ethernet bus.

Sonar data is only bridged if network sonar is turned on. Below is an example of sonar data 

being shared between two displays.
