Frequently Asked Questions (FAQ) – Expert Insights
Q: What is the transmission power of the ONWA KS-33NT_X?
A: The KS-33NT_X outputs a powerful 12.5 Watts (41 dBm ± 1.5 dBm), providing significantly greater transmission range across the open sea compared to standard 2W or 5W AIS trackers.
Q: What is the exactTrax satellite technology used in the KS-33NT_X?
A: exactTrax allows the AIS tracking beacon to transmit specialized low-orbit satellite messages, enabling fishing fleets and vessel operators to monitor buoy and gear positions globally, beyond the horizon of shore stations and vessel VHF antennas.
Q: How does the encryption feature protect commercial fishing gear?
A: The KS-33NT_X incorporates proprietary ONWA encryption that scrambles position coordinates so that only authorized ONWA chartplotters programmed with the matching encryption key can decode and display the buoy’s location, preventing rival boats from locating valuable nets and longlines.
Q: How long does the internal battery last between charges?
A: The high-capacity rechargeable lithium battery delivers up to 360 hours (15 days) of continuous transmission at standard reporting intervals.
Q: Is the unit fully waterproof?
A: Yes. The casing is constructed of high-impact marine ABS polymer rated IPX7 waterproof, capable of withstanding rough sea wave impact and shallow submersion.
Q: How is the beacon programmed?
A: The unit is easily configured with vessel MMSI, callsign, encryption keys, and transmission interval using the included ONWA Tracking software and USB programming cradle.
