The minimum specifications for the uninterruptible power supply are:
•
Input voltage
: The input voltage must fit vessel supply voltage
•
Output voltage
: 230 VAC, 50 Hz
•
Output power
:
– Processor Unit and display: 1000 W
– Transceiver Unit: 1500 W
•
Output form
: The output AC voltage must be a sine wave
Speed log
In order to operate correctly, the SN90 requires input from a speed log.
Note
Without the input from a speed log, the SN90 will neither be able to present correct
navigational information, nor compensate for vessel movements. This lack of
compensation will prevent the SN90 from providing correct echo information.
In most cases a suitable sensor is already installed on the vessel. A global positioning
system (GPS) with a fitting output format can also be used.
The speed log interface requirements are:
•
Serial line
: Standard NMEA 0183 telegram format
•
Ethernet
: Standard NMEA 0183 telegram format
Course gyro
In order to operate correctly, the SN90 requires input from a course gyro. A course
gyro is not a part of the SN90 delivery.
Note
Without the input from a course gyro, the SN90 will not be able to present correct
navigational information.
In most cases a suitable course gyro is already installed on the vessel. A global
positioning system (GPS) with a fitting output format can also be used.
The course gyro interface requirements are:
•
Serial line
: Standard NMEA 0183 telegram format
•
Ethernet
: Standard NMEA 0183 telegram format
