To connect the display unit to the SeaTalk bus, connect a standard
SeaTalk cable between the SeaTalk connector on the rear of the display
and a SeaTalk instrument or the SeaTalk bus.
Standard SeaTalk cables are available in a range of lengths (part
numbers W284 to W287), and cables for connecting to older SeaTalk
units are also available (part numbers D187 or D188).
NMEA Output to External Navaids
The NMEA Output cable should be connected to the upper, left
connector on the rear of the display unit.
Note: The NMEA Output cable is fitted with a ferrite clamp to ensure
EMC conformance.
Note: The display unit does not supply power via the connector.
A separate power connection to your NMEA units is required.
Power and NMEA Input Connection
The DC power and NMEA input should be connected at the rear Power/
NMEA J5 seven-pin connector. The connector (viewed from the outside)
and pin functions are shown in the following diagram and table.
