10 FRONT PANEL DISPLAY
11 OPERATION
11.1 Switching On
When the 12 V dc supply is switched ON then the green ON LED will light and the other six LEDs
visible on the front panel of the unit will illuminate twice for a period of one second on each
illumination. The
Status, Error, TX Off and TX LEDs will then go out.
The green RX LED will flash when it is receiving data from other AIS units.
When the internal GPS is locked the yellow LED will go out and the green Status Led will light; note
that this process may take up to 30 minutes depending on the switch-on state of the GPS receiver.
The red TX LED will flash momentarily every time the unit transmits.
11.2 Warning and Fault States
If the unit has not been able to transmit a position report during the last expected two reporting
intervals (
i.e. the nominal reporting interval cannot be maintained for operational reasons such as a
Message 23 quiet period, high channel load conditions, etc .) the yellow LED will illuminate. This is a
warning condition only and indicates that your vessels position is not currently being reported to
other vessels. Reception of other vessels AIS information by the CSB200-S is not affected. When the
unit is able to commence reporting the yellow LED will go out.
If a fault occurs then the red Error LED will illuminate. This may illuminate briefly if the power supply
is interrupted or if the VHF antenna characteristics are briefly affected.
If the red Error LED illuminates continuously then the unit should be assumed to be faulty and should
either be switched off (power removed) or if this is not practical, any other vessel position information
derived from the unit should not be used and it should also be assumed that the unit is not
