Common Question of em-trak R300
What is the R300 receiver?
The em-trak R300 is an AIS receiver for compatible navigation or display systems. It receives vessel-identification transmissions but does not necessarily transmit the vessel’s own information. Confirm antenna, GPS requirements, display connection, power supply, wiring, software, and AIS receiver system compatibility before installation.
Does it transmit AIS data?
No. The R300 is identified as an AIS receiver, so it receives traffic data rather than broadcasting the vessel’s own identification. Confirm antenna connection, output format, display compatibility, power supply, and software before operation.
Is it an anchor windlass?
No. The R300 receives AIS traffic and does not operate a gypsy, drum, chain, or anchor rope. It is not an anchor windlass component. Verify separate equipment for marine anchor retrieval.
