9 Pin D – 9 Pin D
Use this cable to connect the SLR-200 receiver to a PC serial port.
Hint:
If you do not have a free serial port then you can use a USB port to
receive the data. To facilitate this you need to purchase a USB to serial port
adaptor. Make sure the adaptor has a driver for your operating system.
The following physical connections are given;
NMEA Output to Plotter
4= Signal (+)
RS232 Output to PC
2= Signal (+)
NMEA Input from GPS

The output data is a VDM string at 38.4k baud rate.
The NMEA input is capable of accepting any sentences at 4800Bd
and multiplexing them with the VDM sentence to the NMEA/RS232
output.

Correct operation

Operation of the SLR-200 unit is fully automatic and only requires
power, VHF and data cable connection.
On powering up the unit
●
The green light marked ON should illuminate.
●
The channel 1 and 2 lights should flash momentarily when
information from nearby transceivers is received.
Data is then output for visual or textual viewing on compatible
electronic charting systems or other systems or devices.
Range of AIS
The AIS reception range is similar to that normally associated with
Marine VHF Radiotelephone. Range is dependent on height of
antenna and also type of antenna, the higher and better antenna
installed the greater the reception range.
Typically an antenna mounted on the rail of a yacht will achieve 15
miles, mounted on the masthead will increase this to 20 miles. Shore
based reception is governed by local terrain, however an open view
to the sea with an antenna mounted in the clear at a height of
approximately 20 metres will achieve 25 miles plus, higher gain
antenna can be used on shore to further increase the range.
