6.3 Configure > General
General settings for the R60 unit are found by selecting the Configure base category
and then select the General sub-category.
The parameters are described in the following table:
Group
Parameter
Description
Identification
MMSI
The MMSI number for the base station site. If the PSS site has two base
stations in a hot standby configuration both base stations shall have the
same MMSI.
Name
The name transmitted in AIS message 24 (if configured
1
). If the PSS site
has two base stations in a hot standby configuration both base stations
shall have the same name.
VDL Settings
Message
Retries
Specifies how many times an ABM message shall be resent if no
acknowledge is received from the remote unit.
Repeat
Indicator
This parameter indicates the repeat indicator value of VDL messages
generated by the base station. The value can be set in the range 0-3,
where 0 is set by default.
RATDMA
Allowed
Select to allow the base station to use RATDMA access to VDL.
LR Broadcast
Control
Use to set long range control bit in base station report (AIS message 4) for
control of Class A transmission of AIS message 27.
UTC Synch
Source
Source
The UTC synchronisation source used by the Base Station.
UTC source alternatives are:
 Internal. Internal synchronisation source is used
 External. External synchronisation is used
 Int W/ Ext Fallback. Internal synchronisation source is used with
external source as back-up in case the internal synchronisation
source fails
 Ext W/ Int Fallback. External reference source is used with
internal source as back-up in case the external source fails
The Fallback alternatives means the base station automatically change to
the fallback source if the base station fails to get UTC time from the
primary source.
It is recommended to primarily use the internal GNSS for UTC
synchronisation. The external option requires that the site is equipped
with an additional time source which is connected to the base station.
Signal Type
Selects which type of signal the time synchronization signal is. If an 1PPS
signal is used then a ZDA sentence must be provided on a serial input.
ZDA Offset
Used to specify the offset between the 1PPS and ZDA sentence, to make
the timing correct.
Local Storage
Enable
