Frequently Asked Questions
What is CSTDMA and how does it benefit the em-trak B923?
CSTDMA (Carrier Sense Time Division Multiple Access) is an advanced AIS transmission protocol that allows the em-trak B923 to dynamically manage its transmissions to avoid collisions and ensure reliable data exchange, even in congested waterways. This results in improved situational awareness and reduced missed targets compared to older TDMA systems.
What connectivity options does the em-trak B923 offer?
The em-trak B923 offers comprehensive connectivity, including NMEA 2000 and NMEA 0183 interfaces for integration with chartplotters and displays, as well as optional Wi-Fi and Bluetooth for wireless connectivity to tablets and PCs.
Can I connect the em-trak B923 to my tablet or PC?
Yes, the em-trak B923 can be connected to a tablet or PC. This is achieved through its optional Wi-Fi or Bluetooth modules, allowing for data streaming to compatible charting applications and devices.
Is the em-trak B923 waterproof?
Yes, the em-trak B923 is built to withstand harsh marine conditions with an IPx6 and IPx7 certification, making it resistant to high-pressure water jets and temporary immersion.
Does the em-trak B923 have a silent mode?
Yes, the em-trak B923 includes a silent mode function, allowing you to temporarily disable its transmissions for privacy or during specific operational scenarios, while still receiving AIS data.
