Led Indicators - Comar Systems CSB200 Installation And Instruction Manual

CSB200 Class B AIS
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.
The unit should be examined by an authorised service agent at the
earliest opportunity.

LED Indicators

ON
This is a green LED which indicates, when lit, that power has been
connected correctly to the transponder.
Status
This is a green LED which indicates, when lit, that the transponder
hardware has been configured, that the operating software is present,
that the CPU has booted up, the application software is running and
everything is correct.
RX
This is a green LED which indicates when flashing that the CSB200 is
receiving data from other AIS transponders and is outputting this data as
VDM NMEA sentences on the output data ports. If the Green LED is on
continuously the unit has not been programmed with its personalised
data. It will still send received data to the output port, but will not transmit.
TX
This is a red LED which flashes momentarily when the CSB200 transmits
its own AIS data.
Timeout
This is a yellow LED which indicates when lit that the transmitter is
prevented from transmitting. Reasons for this include the following:
•
The transponder's internal GPS receiver is not operating or is
not yet ready.

CSB200 Class B AIS
•
The transponder was unable to transmit an AIS message due to
the channel being already occupied, e.g. by transmissions from
other AIS transponders, or the TX Off function is in operation.
Error
This is a red LED which indicates, when lit, one of the following status
conditions is possible:
•
Transmitter lockout timer (1 second maximum) has operated
•
GPS is unable to gain lock after 30 minutes
•
VHF antenna VSWR is out of range
•
Power Supply is out of range
•
Background noise level is above the threshold level (-77dBm)
Transmit Off Facility.
The Blue LED can be configured to operate in 3 modes by the proAIS
program:
•
Switch has no function, default mode as supplied.
•
Silent mode facility is provided in the event that you do not wish
to disclose your position to other users or to conserve power
when it is not necessary to transmit your position. The
transmitter can be turned off by connecting a simple ON/OFF
switch between the Blue cable on pin 6 and the Green cable on
pin 5. Closing this switch will cause the Blue-TX off LED and
the Yellow Timeout LED to light, the Green Status LED will
extinguish. Opening the switch will resume transmissions.
Reception of AIS data during this operation will not be affected.
•
Send Safety Related Message will send a Type 14 message
with your MMSI number and the words MAYDAY MAYDAY. The
message can be turned on by connecting a momentary push on
button between the Blue cable on pin 6 and the Green cable on
pin 5. Holding the switch down for 3 seconds will activate the
function and cause the blue LED to light, it will stay illuminated
for 1 minute, further pushes of the switch, after the Blue LED
extinguishes, will repeat the message.
