Common Concerns Answered
What is the FCC programming requirement?
The em-trak B953, like all AIS transceivers sold in the US, requires FCC programming by a qualified technician to register the vessel's MMSI and details. This is a regulatory requirement for transmitting AIS data and ensures proper identification on navigational displays.
Can I return the em-trak B953 if I have an issue?
For product issues, direct contact with the manufacturer is required as returns are not processed through the point of purchase. This streamlined manufacturer support ensures efficient resolution for technical problems.
Is the installation complex due to the programming requirement?
While the FLEXI-FIT™ bracket simplifies physical mounting, the FCC programming step requires a certified technician. However, basic wiring to NMEA 0183/2000 and power is straightforward, making the overall installation manageable.
Frequently Asked Questions
What is SOTDMA and how does it differ from standard Class B AIS?
SOTDMA (Self-Organizing Time Division Multiple Access) is an advanced transmission protocol that provides greater control over the AIS network. It offers a 5W transmission power, compared to the 2W of standard Class B, resulting in longer range, improved target clarity, and reduced transmission collisions, particularly in crowded marine traffic.
Does the em-trak B953 require a separate VHF antenna?
No, the em-trak B953 features an integrated VHF antenna splitter. This allows it to share your existing VHF radio antenna, simplifying installation and reducing the need for additional equipment.
What is required for the FCC programming of the em-trak B953?
FCC programming requires a qualified technician to input your vessel's Maritime Mobile Service Identity (MMSI) number and other essential vessel data into the transceiver. This process ensures compliance with FCC regulations for AIS operation.
Can the em-trak B953 be installed on a 24V DC system?
Yes, the em-trak B953 is designed for dual voltage operation and is compatible with both 12V DC and 24V DC systems, making it suitable for a wide range of vessels.
What chart plotters or PCs are compatible with the em-trak B953?
The em-trak B953 is compatible with any chart plotter or PC software that supports NMEA 0183 or NMEA 2000 data input. Its widespread connectivity ensures integration with most modern marine electronic systems.
