Connects to ground.
Connects to the NMEA input/
output connector of a transceiver to
–
output GPS data, or to transmit an
Individual DSC call. (p. 31)
The data communication speed
(baud rate) can be selected
,

between 4800 bps (IEC61162-1)
, RMC,
1
and 38400 bps (IEC61162-2) for
each Input/Output port. (Default:
4800 bps)
Connects to a plotter device or
marine radar to output the received
AIS messages and GPS data.

Connects to an external GPS
receiver to input GPS data.
The data communication speed
(baud rate) can be selected
,
2
between 4800 bps (IEC61162-1)
and 38400 bps (IEC61162-2).
(Default: 4800 bps)
Connects to a switch button to turn
OFF the TX function.
–
When a short occurs between pins
1 and 10, transmission is inhibited.
An active logic is set to High
level while an alarm sounds if a
–
malfunction occurs, an AIS target
is closer than your CPA and TCPA
settings, or so on.
