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.

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 ACU interfaced to the 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.
