4. Basic Setup of the ACU
4.1. Operator Settings
Refer to the Operation chapter of this manual to set the Ship information. Latitude and Longitude should
automatically update when the GPS engine mounted on the antenna pedestal triangulates an accurate location, but
you may enter this information manually to begin. Except when integrating NMEA-0183 Gyro source, you will have to
enter the initial Heading of the ship, subsequently the ACU will then increment/decrement as the Gyro Compass
updates.
Next, set the Satellite information. Longitude of the desired satellite you wish to use and the receiver settings for it are
especially important.
At this point you should be able to target the desired satellite. Continue with the setup steps below to optimize the
parameters for your installation.
4.2. SETUP Parameter display and entry menus.
Press and hold BOTH the LEFT and the RIGHT arrow keys for 6 seconds to access to the
system setup parameters (at the EL TRIM selection).
Press BOTH the LEFT and the RIGHT
arrow keys
momentarily
to access to the

parameter.
Access is only required after installation or repairs of your antenna system. These parameters
should only be changed by an authorized service technician.
CAUTION: Improper setting of these parameters will cause your system to not perform properly. Also refer to the
SETUP section of your Antenna manual.
4.3. Default Setup Parameters for your Antenna
The following table shows the factory default parameters for the DAC-2202 Antenna Control Unit interfaced to a
Series 09 Antenna PCU. When you receive the system it will have factory default settings in the ACU. After
installation of the system, some of the settings will remain at factory default and others should be optimized for
specific applications.
