Networking Constraints - Raymarine e7 Installation Instructions Manual

2.6 Networking constraints

The following constraints apply when networking an e7 / e7D
multifunction display with other devices.
General
• e7 / e7D displays must be connected together using SeaTalk
• e7 / e7D displays can be connected via NMEA 0183 or SeaTalk
but not all functions are supported.
Master / slave operation
• Any system featuring more than one e7 / e7D display must have
one of the displays designated as the data master.
• Any system featuring e7 / e7D display(s) and an E90W, E120W,
or E140W display connected using SeaTalk
the displays designated as the data master.
• e7 / e7D displays are always designated as slaves when a
G-Series unit is connected to the system using SeaTalk
Homescreen sharing
• For networks featuring ONLY e7 / e7D displays:
– Networked e7 / e7D displays share homescreens.
• For networks featuring e7 / e7D and non-e7 / e7D Raymarine
displays:
– e7 / e7D displays will share homescreens.
– e7 / e7D displays will NOT share homescreens with E90W,
E120W, or E140W displays.
– e7 / e7D displays will NOT share homescreens with G-Series
units.
Cartography sharing
• Chart card cartography is shared between e7 / e7D displays.
24
• Only chart card cartography that is purchased separately to the
e7 / e7D display can be shared with E90W, E120W, or E140W,
or G-Series units. Chard cards that are included with the e7
/ e7D multifunction display at the time of purchase are NOT
shared between e7 / e7D displays and E90W, E120W, E140W,
or G-Series units.
hs
.
• Embedded cartography can NOT be shared between e7 / e7D
displays.
ng ,
• The cartography contained on chart cards is always used in
preference to embedded cartography when a chart card is
inserted into a card slot.
Radar operation
• e7 / e7D systems support the use of one radar scanner at a time.
hs must have one of
• The data supplied by a connected radar scanner is repeated to
any networked displays.
hs . Sonar operation
• You can connect an external Digital Sounder Module (DSM) unit
to e7 / e7D displays via SeaTalk
• "D" model variants of the e7 displays include a built-in Digital
Sounder Module and the display can be directly connected to a
compatible sonar transducer.
• If an e7D display detects a connected and powered external DSM
unit the internal DSM is automatically disabled.
• You can only use one sonar transducer at any one time.
• The data supplied by an internal or external DSM is repeated to
any networked displays.
