CTRX GRAPHENE Manual
Before the AIS CTRX GRAPHENE has been programmed, both the yellow and red LED’s
will light, indicating that the unit is not programmed (no valid MMSI number). This is shown
both on the transponder and on the status panel in proAIS2
The green
Power
LED on the transponder panel indicates that the transponder is connected
to a DC supply and powered on.
The red
Error
LED indicates the following errors:
• The transmitter has transmitted longer than 1 s.
• The GPS has not started to navigate after 30 minutes
• Excessive VSWR value (> 3:1) (faulty antenna or cable problem).
• Faulty transmitter (no or low power output).
• A severe fault which prevents normal operation
The yellow
TX timeout
LED will turn on to indicate a change in the operating status. The
situation has called for the transmitter to stop transmitting.
The yellow
TX timeout
LED can indicate the following conditions:
• The transponder GPS has not received a position fix which means that the
transponder cannot transmit as the position data is invalid.
• The GPS receiver is waiting to acquire a position fix (
LED
is flashing)
• The transponder has not been able to transmit because free slots are not available.
This can be due to disturbance from radio and/or electrical equipment on board or the
AIS traffic situation (many transponders in the same area).
When the situation has been resolved the yellow LED will turn off and the green status LED
will be turned on (on the front panel of the transponder). This is the normal operating
condition.
The blue
Silent Mode
LED will light up when AIS CTRX GRAPHENE is set in silent mode,
which turns off the transmitter. This sets the transponder in receive-only mode. This is
referred to as
”SILENT MODE”.
The transponder can be switched to SILENT mode by either pressing
the “S” button on the
front panel for 3 seconds or by using an external switch (see page 21 for wiring instructions)
To switch off the SILENT mode hold the “S” button down for 3 seconds. The blue LED will
turn off after approximately 1 second.
A third way to switch the unit to SILENT MODE is to use the software button (marked Silent
Mode) in proAIS2 status window were the function can be remotely switched on and off.
NOTE
that this is a special function in proAIS2 and that it is separate from the hardware
control to set the silent mode with the switch.
In the
Statistics
window received and transmitted messages on the two channels is shown.
The values are accumulated from the time the transponder was connected up to the proAIS
program. The values will be reset as soon as the connection is disconnected.
