Smart Radio SR161 AIS Receiver

The SR161 can provide years of service when used with a computer's standard RS232 serial port interface or a compatible chartplotter. It is not designed to be used with chart plotters employing a NMEA standard (RS422) interface (such as Raymarine C,  E and G Series or Garmin 4000 and 5000 series).  If you need an AIS solution for use with a chart plotter, please consider one of our NMEA-compatible AIS receivers  or any of our AIS transponders

• Single channel receiver that scans between the two AIS frequencies
• When interference is detected on one receiving channel, the SR161 automatically switches to the alternate AIS channel
• High-sensitivity AIS data reception
• Line of sight reception similar to marine VHF reception distances
• Very low power consumption
• Receives AIS Class A and Class B vessel reports
• Sends information to a PC via a serial interface
• Ability to track and display information on multiple targets
• Easy installation: connect a VHF antenna (not included), 12 volt DC power and a serial cable to your PC
• Can be used with your existing VHF marine radio antenna with an appropriate splitter
• Can be used to consolidate incoming NMEA positional data from a GPS into a combined high-speed data stream on a single serial port.

The SR161 can be used with many popular computer-based marine navigation packages. Any navigation package that can process NMEA VDM data from a serial port should work with the SR161.
