Description
em-trak R300 | High-Performance Dual-Channel AIS Receiver
Engineered to overcome coastal traffic blind spots, the em-trak R300 is a sophisticated dual-channel AIS receiver designed to feed real-time target data to your vessel’s navigation suite. By simultaneously monitoring both AIS frequencies, this unit ensures that every vessel name, course, and position update is captured and displayed on your chartplotter, providing a vital layer of collision avoidance for recreational mariners.
Designed for easy integration via NMEA 2000 or NMEA 0183, the R300 features low power consumption for continuous 24/7 monitoring. Using a high-quality, dedicated VHF antenna is critical to maximizing the receiver’s range, ensuring that even weak signals from distant AIS-equipped vessels are reliably captured and processed by the internal digital engine.
Technical Key Features
- Dual-channel AIS receiver for rapid updates.
- NMEA 2000 and NMEA 0183 connectivity.
- Low-power 12V/24V DC consumption logic.
- Compact, rugged housing for internal mounting.

em-trak R300 AIS Receiver Technical Guide
The R300 is a high-performance dual-channel receiver. It monitors both AIS frequencies simultaneously, ensuring that all surrounding vessel data—including static, dynamic, and safety messages—is captured in real-time.
The R300 is designed for versatility, offering NMEA 2000, NMEA 0183, and USB outputs. This allows you to feed AIS data to a modern dashboard MFD and a backup laptop navigation system at the same time.
No, the R300 is a receive-only AIS device. It is intended for boaters who want the safety of seeing large ships on their display but do not need or want to broadcast their own position to other vessels.
The unit is designed for ultra-low power consumption. This makes it an ideal choice for sailors and small powerboats where battery capacity is limited and every milliamp counts during long offshore passages.
The R300 features a compact and durable housing that is built to withstand the marine environment. Its small footprint allows it to be easily installed in tight spaces behind the helm or in a protected electronics cabinet.
