Why do I need an SLR-200?

Originally designed to improve safety at sea, most vessels over 300 tons are required to fit AIS transponders before the end of 2004 and all before the end of 2007.

The SLR-200 provides a small vessel with:

A low cost method of monitoring the position, speed and heading of other vessels within VHF range.
The ability to plot the progress, changes in heading and speed of other vessels on the screen of your onboard PC.
A vessel's name, call sign and MMSI number to call up the target vessel on a DSC radio and ascertain their intentions.

The CSB200 provides a small vessel with:

Automatic transmission of the vessel's own position, speed and heading to other vessels within VHF range.
A method of monitoring the position, speed and heading of other vessels within VHF range.
The ability to plot the progress, changes in heading and speed of other vessels on a PC or Chart Plotter.
A vessel's name, call sign and MMSI number to call up the target vessel on a DSC radio and ascertain their intentions; automatic transmission of the vessel's own position, speed and heading to other vessels within VHF range.

The SLR-200 provides the Vessel Monitoring capability for small ports and harbors

That cannot justify an expensive Class ‘A’ unit, to monitor traffic within VHF range.
To track vessels transiting areas and check on legality of transit, compliance with speed regulations, etc.
To monitor their own vessels operating inside VHF range.

Installation

Installation is quick and simple. The SLR-200 requires a 12/24 V DC power source, connection to a PC via the serial port, and connection to an external VHF aerial (not supplied). The SLR-200 is compatible with electronic chart systems capable of accepting standard NMEA 0183 AIS sentences. For information about compatibility, please consult your Navigation Software supplier.
