CSB200 Class B AIS
USING THE TRANSPONDER
Switching on
When the 12VDC supply is switched on the green ON LED will light and
the other six LED's 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.
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 vessel AIS information by the CSB200 is not affected. When the
unit is able to commence reporting the yellow LED goes out.
If a fault occurs 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 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
transmitting valid position information for your vessel.
