Description
1 GND – – Connects to ground.
2 NMEA IN (–) Input level:
Less than 2 mA
(at 2 V applied)
–
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)
and 38400 bps (IEC61162-2) for
each Input/Output port. (Default:
4800 bps)

Connects to an external GPS
receiver to input GPS data.
The data communication speed
(baud rate) can be selected
between 4800 bps (IEC61162-1)
and 38400 bps (IEC61162-2).
(Default: 4800 bps)

10 TX OFF
Active:
Connect to
ground
–
Connects to a switch button to turn
OFF the TX function.
When a short occurs between pins
1 and 10, transmission is inhibited.
11 ALERT
Load rating:
DC 3.3 V/1 mA
(maximum)
–
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.
12 NC – – –
*1 Only 38400 bps.
*2 When a received GPS signal does not include a GBS sentence, the transponder will
not receive the signal from the external GPS receiver.
*3 May not be sent, depending on the presetting.
