ACR Electronics 2662 - Manual (Page 42)

Setting the Internal and External GPS Antenna Position.
Note: It is critical for the proper orientation of your ship to other AIS users to enter this
data accurately.
Example: Length of ship = 220m and Beam = 43m.
GPS ANTENNA location on ship (is x in above Menu example) is located 200 meters from
bow (A) and 33 Meters from Starboard side (D).
Note: If no external GPS is connected, then enter same data as for internal GPS. External
GPS antenna reference point must be filled in before you can save.
Ref.Points ext (Position of the external GPS antenna)
A = 200m the distance from bow (front) to the antenna.
B= 20m the distance from the antenna to the stern (rear)
C = 10m the distance from the port (left) side to the antenna
D = 33m the distance from the antenna to the starboard (right) side
Enter Ref.Point int (location of the internal GPS antenna) in the same way.
A = 220m the distance from bow (front) to the antenna.
B= 0m the distance from the antenna to the stern (rear)
C = 10m the distance from the port (left) side to the antenna
D = 33m the distance from the antenna to the starboard (right) side
Your int/ext reference points must match the entered ship dimensions. Length of ship = 220m
and Beam = 43m. For incorrect dimension the AIS shows:
>>> ext/int ship len/beam don't match
Rounded up value of Len and Beam in [dm] must match Len (A+B) and Beam (C+D) in [m]
other the AIS shows:
>>> Convoy len must match rounded A+B
After correct settings of the reference points and dimensions you can press M5 - [Save]. to
save your settings:
>>> DATA OK. PRESS M5 TO SAVE DATA <<<
Save the new settings by pressing [Save].
Press [Back] return to the Main Menu Screen without saving any changes.
