Commands tab
The commands tab provides access to software controlled features of the AIS500 Transceiver. Depending on the AIS software
version the following commands may be available:
•
Silent
mode
o
Buttons to enter / exit silent mode. In Silent mode the transmitter is disabled and no position reports are
transmitted by the unit. Other AIS users will be unaware of your position in this mode so it should be used with
caution and only where allowed by local regulations.
•
Safety related message
o
A button is provided to trigger the transmission of a Safety Related Message. Clicking this button will display a
confirmation dialog box. Clicking 'OK' in the confirmation dialog box will cause a Broadcast Safety Related
Message with the contents "MAYDAY MAYDAY" to be transmitted to all other AIS equipped vessels and base
stations in the area.
•
Configure baud rates
o
Baud rates for the RS232 and RS422 (NMEA 0183) communications ports can be set here. The default value
is 38400 & should be used where possible. The 'Update' button should be clicked to send new settings to the
AIS Transceiver.
•
GPS
output
options
o
By default the AIS Transceiver will output its current GPS position data every four seconds via the RS232 and
NMEA serial interfaces. This information is sent using the GPRMC sentence and can be used to provide your
vessels GPS position to a chart plotter connected to the unit. A higher position update rate (once per second)
is available as an option and will result in a more accurate display of your vessels position, speed and course
on a connected chart plotter. To use this option select the "Output GPS data every second" option and click
'Update'. It is also possible to disable GPS NMEA data output from the unit (if you have another source of
GPS data).
•
Alarm
output
options
o
By default the AIS Transceiver will output the status of all alarms every minute using AIALR sentences. The
unit can optionally be configured to only output active alarms using the radio buttons. The 'Update' button
should be clicked to send new settings to the AIS Transceiver.
