NAUTICAST A2 User manual
Installation Guide
1001001-3
RECOMMENDED PHYSICAL INSTALLATION
Transponder unit should be mounted in a protected area and compass
safe distances kept in mind (see table on the right). VHF antenna must be
mounted vertically, free of reflective objects, minimum distance to other
VHF antennas 1.5m and out of the radar beam. GPS antenna must have
an omnidirectional view of the sky for ideal reception.
SYSTEM MODE
Important: The Nauticast A2 can operate in two different system modes,
Class A mode (default) and Inland mode.
Inland mode is applicable to European river going vessels. Set mode in:
Main MenuConfigSystem SettingsSystem Mode
Instructions only relevant for Inland AIS operation will be in
brown print.
This installation guide serves as a complement to the
product manual (Art.No. 1001001-2), included on the
Nauticast Data Card (USB-Stick).
Installation of the
Nauticast A2 AIS System should always be planned
and executed by authorized personnel.

*SET SHIP DIMENSIONS
There are two methods for setting Ship Dimensions: configuration
parameter “Ship Size Mode” in the view “Config-> Interfaces ->
Miscellaneous” can be set to Standard Mode or Simplified Mode
(default). This choice is only available in Class A system mode!
If external ECDIS will be used for full AIS configuration, Standard Mode is
recommended unless the ECDIS integration has been verified with A2.
Standard Mode (not available in Inland mode)
In this mode data is entered exactly as is will be reported on VHF link.
Input:
•
A, B, C, D
for internal antenna [m]
•
A, B, C, D
for external antenna [m]
Simplified Mode (default)
In Simplified mode the transponder will automatically calculate and
correctly round the A,B,C and D values reported on the VHF link from
Length, Beam, C and B.
Input:
•
Ship length x.x
[m] (one decimal precision)
•
Ship beam x.x
[m] (one decimal precision)
•
C, B
for internal antenna relative to ship x.x [m] (one
decimal precision)
•
C, B
for external antenna relative to ship x.x [m] (one
decimal precision)
Inland Mode Convoy Setting (Inland only):
Set Length, Beam, C and B parameters as above.
Specify any extra convoy size in
Main MenuVoyageConvoy Settings
.
Extra convoy size on each side (value = 0 if convoy not used):
•
Bow x.x
[m] (one decimal precision)
•
Stern x.x
[m] (one decimal precision)
•
Port side x.x
[m] (one decimal precision)
•
Starboard x.x
[m] (one decimal precision)
A,B,C and D values reported on the VHF link will be calculated from
Length, Beam, C,B and any extra convoy sizes.
This mode will make it easier for Inland AIS users to quickly change all
relevant dimensions when changing convoy configuration, but may cause
problems for external ECDIS integrations.

SYSTEM FUNCTIONAL TEST
Please consult the product manual, included on the Nauticast Data Card
(USB-Stick), if any problems are detected.
SYSTEM POWER UP
The Nauticast A2 will start to operate when power is connected, the device
does not have a power switch. The system is fully operational within 2
minutes.
TRANSPONDER STATUS LEDs
Normal operation can be verified using the LEDs on the front. Tx and Rx
LEDs will flash during VHF Tx and Rx. Status LEDs on the transponder
signal these operational states:
SYSTEM STATUS

Normal Operation
Solid GREEN
Unacknowledged active alarms

Note: LEDs will behave differently during a system boot. Allow two
minutes from power-on before checking of LED status.
ALARM LIST
Make sure no unexpected alarms are active.
Main Menu Alarms
Disable any active alarms not applicable for the installation in the Alarm
Config View

TIME AND DATE
Verify system time and date in the upper right corner. If incorrect, the
transponder internal GPS does not have a position fix. This will also be
indicated by an alarm “UTC Sync Invalid”.

Mounting
The Nauticast A2 can be panel or gimbal mounted (optional accessories
1001005 or 1001006). For flush mounting, remove the gimbal mount
jacket. Use the cutout dimensions in the figure below. Do not exceed the
cutout area, the screw holes may be too close to the cutout. A 1:1 scale
cutout drawing is included on the Data Card. If printed, verify scale has
not changed by measuring given dimensions.
