GPS input
Term# Function Note
8A NMEA in 8 Connect to GPS NMEA "A" output
8B NMEA in 8 Connect to GPS NMEA "B" output
GPS info received is only used for diagnostic purpose. This is an optional but recommended
connection with the intention to simplify troubleshooting of the speed log system.
Alarm Acknowledge input
Term# Function Note
9A NMEA in 9 Connect to brid
e alarm panel
9B NMEA in 9 Connect to brid
e alarm panel
If an NMEA alarm ($xxALR,,,A,V,) is sent out from the Sig. Distributor to the bridge alarm
panel, the alarm can be acknowledged using NMEA in 9.
E.g. to acknowledge an ESD alarm such as: $SDALR,,150,A,V,Shallow alarm, a
corresponding: $SDACK,,150 shall be sent to this input from the central alarm panel.
Digital inputs (opto-isolated)
Term# Function Note
14+ OPTO in2 LOG 1 SOG silent mode
14- OPTO in2
When Opto in 2 is activated, the acoustic transmission from the SOG part of log 1 stops, if
applicable.
Term# Function Note
16+ OPTO in4 LOG 2 MAIN
16- OPTO in4
When activated LOG 2 becomes the active log
Input choices:
LOG 2 MAIN
LOG 1 SOG MUTE
LOG 2 SOG MUTE
Display INVERT OFF
These electrical inputs are galvanic separated from the Sig. Distributor by opto couplers. The
OPTO inputs can detect an input voltage above 3,5VDC. Maximum input voltage is 40VDC.
