7.6. Pedestal Control Unit Configuration (xx97B & xx00)
The PCU is designed to be used with a variety of antenna pedestal configurations. 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 xx97B. In this configuration the PCU will
not drive any of the three torque motors to prevent damage to the unknown pedestal.
To configure the PCU, select the REMOTE COMMAND window on the DAC-2202. Refer to the table below to key in
the appropriate value for you model antenna.

7.7. Antenna Stowing Procedure
WARNING: Antenna Pedestal must be properly restrained (stowed) to
prevent damage to wire rope isolators, isolator springs and/or antenna pedestal
mechanism during underway conditions
when power is removed from the
antenna assembly.
The normal operating condition for the Sea Tel Antenna system is to remain powered up at all times. This ensures that
the antenna remains actively stabilized to prevent physical damage to the antenna pedestal and reduce condensation
and moisture in the radome to prevent corrosion. If, for some reason, the antenna must be powered down during
