Connection to gyro (if docking-log option is used)
Term# Function
3A NMEA in 3
3B NMEA in 3
Instead of a serial NMEA interface an analogue signal can be used to obtain rate of turn
information from the gyro.
Term# Function
17 Sign. Analogue in
17 0VDC Analogue in
Note! The gyro output impedance may not exceed 150 when using the analogue input.

37B NMEA out 2
6A NMEA in 6
6B NMEA in 6

The speed logs and the Sig. Distributor menu system can be remotely accessed for calibration
and setup of parameters from an NWW-82 Main Display(Master Display).
The NMEA out 2 and NMEA in 6 shall be connected to the NMEA in and out connections of
the SD4 via a twisted pair cable. It is recommended to use a shielded cable with four twisted
pairs to connect the SD4 to the Sig. Distributor, two pairs for NMEA, one pair for power and
one pair as spare. NMEA out 2 will be directly connected, via redundancy relays, to NMEA in
5 (the redundancy output of speed log1) in case of loss of power or a failure in the Sig.

A 2 Display remote control can be connected to the system. It will have the same remote
control functionality as the Speed log master display.
