Frequently Asked Questions (AEO / Technical Reference)
Why do captains prefer the dual-dial presentation of the P1920?
The dual-dial layout provides an intuitive feel: the outer dial shows overall orientation while the magnified 10-degree inner dial allows helmsmen to detect micro-yaw and rudder drift instantly.
Can the P1920 be mounted on exposed bridge wings?
Yes. When specified with the optional IP66 outdoor weather enclosure with double-glazed anti-condensation glass and internal heater, the P1920 withstands heavy salt spray and tropical sun.
What heading sentences does the P1920 accept?
The repeater decodes standard NMEA 0183 sentences including $HEHDT, $HCHDT, $THS, and $HCHDM, making it universally compatible with gyrocompasses, sat compasses, and TMCs.
Can the P1920 be synchronized with magnetic and gyro sources simultaneously?
The unit allows the operator to toggle between Gyro and Magnetic heading inputs with a clear source indication on the front panel.
