Introduction • There are 3 networks in the HDS system: – Ethernet – high speed point-to-point – Multipoint connection requires use of NEP-1 type switch – NMEA2000 – medium speed bus – NMEA0183 – low speed point-to-point
• This presentation will explain how data is moved around
the HDS system and how the 3 networks interact.

Sonar Auto configuration • If I do an ‘Auto configure’ how does Sonar get setup? – HDS will choose digital depth source as: – Local sonar Xducer. If not available then… – HDS sonar Xducer. If not available then…. – A NMEA2000 depth transducer.
– HDS will choose water temp. source as: – NMEA2000 device. If not available then… – HDS Sonar transducer. If not available then… – Local sonar transducer. – HDS will choose water speed source as: – Local sonar Xducer. If not available then… – HDS sonar Xducer. If not available then…. – A NMEA2000 depth transducer.
• Auto Configure does not setup the scroll source. This is done manually via the Sonar menu. 7
Manual sonar source selection. • Sonar scroll data source is selected under the SONAR MENU as ‘this unit’ or another HDS on Ethernet. This a global setting.
– Digital Depth: From graph source in sonar page follows the scroll data source. – Temp will change with sonar source as long as it has not be configured to be used with a NMEA2k Temp.
• Temperature, depth and speed data source for data overlay is selected in the DATA SOURCES Menu. – If the source selected is SONAR then the source will be the same as that in the SONAR MENU and the data obtained from Ethernet. – If the source is not sonar then data will be obtained from NMEA2000.

NMEA0183 data flow • All supported NMEA0183 Receive sentences are bridged to NMEA2000. • All enabled NMEA0183 Transmit sentences can be sourced from:
– the local unit e.g. internal GPS – NMEA2000 – Ethernet (When SONAR is source)

Limited waypoint sharing
12
Limited waypoint sharing over NMEA2000 • With limited waypoint sharing over NMEA2000 you can: – Add a waypoint with name, icon, position and color to all other live HDS or LCX displays
• You CANNOT edit a waypoint on another display in any way. i.e. waypoint edits only effect your display.

14
Full waypoint sharing
cont.
• When waypoints are shared over Ethernet all changes are synchronized with all other displays on the network: – – – –
Add a waypoint with name, icon, position and color Edit all attributes Delete Move
• If I change a waypoint on one HDS display while the other is POWERED OFF, will the change be reflected on the other display next time both displays are POWERED ON? – YES. This will happen automatically.
15
Other data shared over Ethernet • A great new feature of HDS is that all data listed below shared over Ethernet is also automatically synchronized like waypoints. • Routes – Not shared over NMEA2000 – Ethernet must be connected • Alarms – Limits and on/off settings apply to all displays. – An alarm can be acknowledged or cleared from any display. – Alarm beeps can be turned on or off for each display. – A log of alarm events on the network is stored.
16
Other data shared over Ethernet Cont.
• System settings e.g. – Language – Units
• Data sources selection
– With global data source setting all displays can be pointed to the same data source. Global is the factory setting for all data sources. Saves setup time. – Individual data sources can also be made local. i.e. a display can be made to use a different data source to the other displays on the network.
17
Data not shared over any network • Trails
– These are stored locally on each display while you are underway. i.e. if a display is off the trail will not be stored on that display and will not be automatically transferred from another display when next powered on. – Can be transferred via SD card.
• Backlighting – Next release
• All non-system settings – E.g text size

Radar and Weather • Radar and Weather work over Ethernet • Multiple displays can display/control Radar and Weather at once. • The radar is a server i.e all radar settings are stored in the radar only. Likewise for LWX-1 weather. • There can only be 1 radar and/or 1 weather antenna on the system.
20
Going BIG! • You can have up to 3 HDS displays on an Ethernet network. • Can use more HDS units on the Ethernet network but speed may reduce depending Ethernet load (radar, weather, etc..) • You can have up to 50 devices/HDS displays on a NMEA2000 network.
