The NMEA in 1 connects to the NMEA out terminal 108 and 109 on the JLN-900 speed log
Sig.Processor.

4.3.1

NOTE! NMEA in 1

NMEA in 1 is supervised by the Sig. Distributor: if there is no NMEA the relay K1 will drop.
NMEA out 7 (terminal 42) connects to the NMEA in terminal on the Speed log
Sig.ProcessorJLN-900.

: NMEA in 5 connects to the redundancy NMEA output (Redundant STW) in Log 1

terminal 120 and 121. This will improve the redundancy of the system. Even if the Sig.
Distributor and/or the speed over ground log are malfunctioning, at least speed trough water
will still be presented on the redundancy outputs.

A second Speed Log can be connected to the Sig. Distributor. The NMEA in 2 and NMEA out
8 shall be connected to the NMEA connections of the Log 2 Sig.Processor via a twisted pair
cable.

NMEA out 1 will be directly connected, via redundancy relays, to NMEA in 1 (the main input
from speed log1) in case of loss of power or a failure in the Sig. Distributor.
