GROUP MMSI
A Group Call provides a method for contacting multiple
vessels with a common interest by using one DSC call.
There is no limit on the number of times you can change the
Group MMSI.

the
CALL
button.
2. Use the or
keys to enter the first digit of the
‘GROUP MMSI’ number.
3. Press the
CALL

4. Repeat until all 9 digits have been entered.
5. To correct an error during entry, press the

repeatedly to move the cursor position to the incorrect

that location.
6. When finished, press and hold the

NOTE:
If the Group MMSI field already has an MMSI
number, press and hold the – key to clear the MMSI field.

USER MMSI
The User MMSI is unique to each radio and must be entered
to enable normal DSC operation - except for the reception
of distress calls which do not require a user MMSI.
The GX600D is shipped from the factory with the user MMSI
‘un-programmed’. It is up to the user to obtain a valid MMSI
from the appropriate licensing authority and enter the MMSI
into the radio to enable DSC operation.
IMPORTANT:
It is a requirement of the regulations that the
User MMSI can only be entered ONCE. If there is a need to
change the MMSI more than once you will need to contact
your authorized GME service centre for advice. For this
reason take special care when entering your User MMSI
number to ensure it is entered correctly before saving it.
To enter the 9 digit User MMSI number issued to
you by your local authority:
1. Select ‘USER MMSI’ from the Main Menu then press the
CALL
button.
2. Use the or
keys to enter the first digit of the User
MMSI number.
3. Press the
CALL
button to move to the next digit position.
4. Repeat until all 9 digits have been entered.
5. To correct an error during entry, press the
CALL
button
repeatedly to move the cursor position to the incorrect
digit then use the or
keys to change the digit at
that location.
6. Once the 9 digit User MMSI has been entered,
double
check to ensure that the number is correct then press
and hold the
CALL
button to store it. The radio will
return to the main menu.
CONNECTING A GPS RECEIVER OR
PLOTTER
You can connect a GPS receiver or GPS Plotter to your
GX600D. A GPS receiver will provide your radio with GPS
position and time reporting. Connecting a GPS plotter will
allow DSC positions of ships to be displayed directly on your
plotter. GPS connections are made through the NMEA ports
on your radio.
NMEA PORTS
The GX600D features two NMEA ports labelled NMEA 1
and NMEA 2. These are available on the rear panel. NMEA
sentences generated by the GX600D will appear on the
output of both ports. In addition, any NMEA sentences
received at the input of one port will be mirrored at the
output of the other port.
The NMEA Baud rate of each port can be set separately
from within the Setup menu. Available Baud rates are 4800,
9600, 19200 and 38400 bps.
NMEA 0183 DATA
The GX600D recognises the following standard NMEA
sentences. You may need to select NMEA 0183 Input/
Output using the interface settings on your GPS, Plotter or
connected device.
NMEA Input from GPS: GPGLL, GPGAA, GPRMC,
GPGNS (v2.x)
NMEA Output to plotter: GPDSC (v2.x) GPDSE (v3.x)
