Installing a Fixed Station (Continued)
25. Slowly
and
gently
turn the antenna by hand towards the reference object.
26. Look through the telescope and turn the antenna gently by hand until the telescope’s vertical
hairline is aligned with the reference object.
27. Press Enter; the following page appears:
28. Key-in the reference azimuth and press Enter; the reference azimuth has now been set.
Note:
When pressing Enter the display may show a slightly different value for the last digit entered.
This is caused by the fact that the resolution of the shaft encoder is 0.003° and so less than
0.001°.
29. Press Next; the following page appears:
30. Press Enter; the cursor(<) starts blinking.
31. Press the
▼
key if the AUTO SEARCH mode is to be switched on; the word OFF changes to
ON, and then press Enter to confirm. If AUTO SEARCH is to remain OFF, press the
▼
key until
it reads OFF and press Enter.
32. Press the
▼
key to go to the parameter ANTI-ICING. ANTI-ICING is OFF by default.
33. Press Enter if automatic switching-on of the antenna heating is desired; the cursor starts
blinking. Otherwise, press Next and continue with step 37.
34. Press the
▼
key; the word OFF changes to ON, and then press Enter to confirm.
Note:
Setting the automatic switching-on of the antenna heating to ON for an explosion proof
station will have no effect, i.e. will not switch the heating on. The antenna unit of an explosion
proof station has no Anti-Icing Supply (AIS) module installed.
35. Press Next; the following page appears:
36. Press Enter if AUTO RECOVERY (default ON) is to be set to OFF (not recommended); press
the
▼
key to change ON to OFF and press Enter to confirm.
37. Press the
▼
key; the cursor points at the parameter CONF.PRTCTED (configuration
protected).
38. Press Enter if the change of settings by the counter station is allowed, then press the
▼
key
to change ON to OFF and press Enter again to confirm. Otherwise, press the
▼
key to go to
the parameter GYRO CMPSAT (gyro compensation).
39. Press Enter and then press the
▼
key to change OFF to ON if the measured azimuth is to
be compensated by a gyrocompass, if for example the Fixed Station is installed on a semi-
submersible and a gyrocompass is used to account for the rotation of the semi-submersible.
Note:
The compensation of the azimuth by a gyrocompass requires that the antenna unit is
connected to a control or client PC to which the gyrocompass can be connected.
Otherwise:
40. Press Next; the following page appears:
41. Press Enter if you wish to change the IP address; the cursor (<) starts blinking.
42. Using the numerical keys 0-9, enter the required IP address and press Enter to confirm.
43. Press Next; the following page appears:
44. Press Menu; the Main Menu Fix appears and the station goes into operation.
Note:
If the servo control mode was set to OPEN LOOP or the operating mode was set to
STANDBY during the configuration procedure, then the servo control mode (Menu 263) must be
set back to NORMAL or the operating mode (Menu 262) must be set back to OPE (operate).
If the auto search function was switched on, the antenna will start scanning between the left and
right auto search scan limits until the station picks up signal from a Mobile Station set for the same
frequency pair and the same selective address code. The antenna will lock onto the antenna of
the Mobile Station and azimuth and distance will be available at the Mobile Station.
If the parameter CONF.PRTCTED was set to OFF, Fixed Station parameters can be modified
remotely fron the Control PC connected to the mobile station, using the Artemis Service Interface.
If no other Fixed Station parameters need to be set or changed using the operating panel, the
operating panel may now be disconnected.
!
Screw the cap of the operating panel socket back on after disconnecting the operating
panel.
