DAC-03 Tracking Antenna Controller Setup
5-1
5. Setup
Below are basic steps to guide you in setting up the ACU. Assure that the Antenna Pedestal (ADE) has been properly
installed.
5.1. Operator Settings
Refer to the Operation chapter of this manual to set the Ship and Satellite information.
1. Latitude and Longitude should automatically update after the GPS engine triangulates an accurate
location, but you may enter this information manually to begin.
2. If you do not have 1:1 Synchro or NMEA gyro heading input, you will have to enter the current
heading of the ship. The Gyro Compass will then keep the ACU updated as heading changes occur.
3. Enter the tracking receiver settings for the satellite you will be using. These receiver settings are
especially important.
4. If the antenna has completed initialization, you should now be able to target the desired satellite
longitude. Continue with the setup steps below to optimize the parameters for your installation.
5.2. Tracking and Band Selection Settings
Press the MODE key to display the current Tracking status display.
To toggle Tracking ON/OFF, press AUX1 or the UP arrow key.
For C, X and Ku band systems the pre-set tracking parameters are changed by selecting the appropriate band
selection in the TRACKING window by pressing the
DOWN arrow. The display will indicate which band ( C ,
X , KuHi or KuLow) is currently selected. The ACU tracking parameters, Terminal Mounting Strip SW1 Band
Selection output AND the Antenna remote C/Ku band select relay(s) may also changed by this selection.
5.3. Default Setup Parameters
Refer to the factory default parameters table in the Setup section of your Antenna Pedestal Manual.
You may need to optimize some of these parameters. Refer to the Setup section of your Antenna Pedestal
manual and the information below to setup the ACU properly for the antenna you are connected to.
Press MODE 4 times, then key in 7979 and hit the ENTER key to access the setup parameters. The
parameters are;
5.3.1. EL TRIM
Elevation trim offset. Adjusts display to correct for antenna alignment errors or imbalances in the
antenna system. Refer to your Antenna Pedestal manual to determine the amount of trim you will
need. Once you have determined the amount of trim required, key in the number of
tenths of
required trim. To increase the elevation value add the required number of tenths of degrees to the
current value of EL TRIM. To decrease the elevation value subtract the required number of tenths
of degrees from the current value of EL TRIM. To enter in a positive value, key in the desired
number of tenths and press ENTER. To enter a minus value, key in the desired number of tenths,
press the NSEW key and then press ENTER.
Continue with Azimuth trim, then re-target the satellite several times to verify that targeting is now
driving the antenna to a position that is /- 1.0 degrees of where the satellite actually is.
5.3.2. AZ TRIM
Azimuth trim offset. Offsets true azimuth display to compensate for installation alignment errors
when used with Ships Gyro Compass input reference. Does not affect REL azimuth reading. Refer
to your Antenna Pedestal manual to determine the amount of trim you need, if any. Once you have
determined the amount of trim required, key in the number of
tenths of required trim. To increase
the azimuth value add the required number of tenths of degrees to the current value of AZ TRIM.
