ship changes direction the display shows change in the same direction. If the direction is
correct but the heading is incorrect go to step C.
3. If the ship's heading is different than the bridge, select the HDG function in the SHIP
display mode by pressing the SHIP key 4 times. Key in the correct heading using the
numeric keys and press ENTER.
7.4. Display Offsets / Optimizing Targeting
If the antenna does not target to /- 1.0 degrees of the satellite actual Elevation and Azimuth
location of the desired satellite, the EL & AZ TRIM parameters need to optimized. The is because the
targeted positions may be different than the calculated look angles due to mechanical installation or
antenna alignment offsets.
Targeting should have been optimized when the system was installed and should not need to be re-adjusted
in normal operation. However, you will need to re-evaluate the elevation trim if the antenna has been re-
balanced.
You may correct the displayed positions to optimize targeting by following the procedure described in the
Maintenance section of your antenna pedestal manual.
7.5. Pedestal Control Unit Configuration
If the power up display of the ACU says SEA TEL – REMOTE “xx97 VER 1.xx” the PCU is not configured for a
specific Series 96, 97 or 00 MODEL number. The configuration information that is unique to each pedestal
type is stored in a Non Volatile Random Access Memory (NVRAM) in the PCU enclosure. If the PCU is
replaced or the NVRAM in the PCU should become corrupt, the PCU must be re-configured to operate with
the pedestal it is installed on. The default configuration for the PCU is model “
xx97 ” (or xx96, or xx00 ).
In this configuration the Level Cage will be driven normally but the PCU will not drive any of the three
torque motors to prevent damage to the unknown pedestal.
To configure the PCU refer to the
Maintenance section of your antenna pedestal manual.
7.6. Programming Instructions Antenna Control Unit
These instructions apply to DAC-2200/2202/2302 and DAC-03 Antenna Control Units with GP32
Processors.
Electrical Hookup – DAC-2200/2202
1. Use a standard straight 9-pin serial cable
(P/N 120643 or equiv.) connected
between the ACU (M&C Port) and a PC
with an available com port.
Electrical Hookup – DAC03 with Software 4.6x
1. Ensure that a PC DAC cable (116670 or
equiv.) is connected between ACU (J11
M&C/NMEA Port) and a PC with an
available com port.
2. Obtain a Copy of the ACU .s19 file and
save in a copy in the same directory as
the ProgTerm files.
3. Click on the “ProgTerm” icon to open the
ProgTerm program.
