Description
Simrad V3100 | SOTDMA Class B AIS & High-Speed Reporting
Optimize your vessel’s visibility using the Simrad V3100, a Class B SOTDMA AIS transceiver that provides increased transmit power and more frequent position updates. By utilizing the same time-slot reservation logic as Class A units, this 5W system ensures your broadcast receives priority in crowded waterways, making it an essential safety upgrade for high-speed powerboats and offshore sailors.
Specifically engineered for integration with Simrad MFDs, the V3100 offers seamless plug-and-play connectivity via NMEA 2000. Correct placement of the external GPS antenna is critical to maintaining the precise UTC time-synchronization required for SOTDMA logic, ensuring your transmissions do not overlap with surrounding commercial traffic during peak network activity.

Simrad V3100 Class B AIS Technical Guide
The Simrad V3100 is a Class B SOTDMA AIS transceiver. It utilizes the same "Slot-division" technology as Class A units, which allows for a higher 5W transmit power and more frequent position updates compared to standard 2W CSTDMA units.
For high-speed powerboats, the V3100’s increased reporting rate is essential. It broadcasts your position more often than standard Class B units, ensuring that other vessels see a smooth and accurate track of your movements on their radar and chart screens.
The V3100 features NMEA 2000 and NMEA 0183 connectivity. This allows it to interface seamlessly with Simrad NSS, NSO, and GO series displays, as well as third-party multifunction displays and PC-based navigation systems via USB.
Yes, the V3100 is supplied with an external GPS-500 antenna. Because SOTDMA requires extremely precise timing to synchronize with the AIS time slots, a high-quality external GPS fix is mandatory for the system to function correctly.
The unit includes a silent mode function that can be controlled via a compatible Simrad MFD or an external switch. This allows you to stop broadcasting your vessel's position while still receiving and displaying all nearby AIS targets for safety.
