NMEA 0183 cable
The NMEA 0183 cable is supplied with exposed wire connecting tails. These should be
connected to your existing NMEA instruments using suitable connector blocks:
SeaTalk High Speed cable
CAUTION: Cable type
To ensure system integrity, only use the Raymarine SeaTalk High Speed
cable to make ethernet connections within your system.
CAUTION: Water ingress
Failure to adhere to the following may result in the ingress of water and
permanent damage to the display:
• Do not remove the SeaTalk High Speed blanking plug from the rear of
the display until such time as you are ready to connect the cable.
• When inserting the cable, ensure that it is clicked AND then turned, in
order to lock it into place and create a watertight connection.
How the SeaTalk High Speed cable connects depends on whether you are integrating
your E-Series Display into a two node, or 3-or-more node system.
Two node system
Connect the cable by way of the crossover coupler to either:
• The display unit and a DSM300, or
• Two displays units.
3 or more node system
Connect the display unit(s) to the SeaTalk High Speed Network switch (E55058).
Note: Please refer to page 17 and page 18 for diagrams of these two systems.
