COLOR STATE DESCRIPTION
Orange Solid
Device initializing
Before the XB can transmit it needs 1 minute to initialize.
MMSI not programmed
You must have a valid MMSI programmed before you can
transmit your position (see configuration section).
Silent mode
Silent mode is on. If this is not intentional check the brown
wire has not been accidentally connected to DC negative
or vessel ground.
Last position report not sent
This may happen from time to time in very busy areas
with lots of AIS traffic. This is normal behavior for
a Class B AIS device.
Flashing
Acquiring a GPS fix
The XB requires a GPS fix before it can transmit its position.
This may take a few minutes. If it is taking a long time check
your GPS antenna installation (see GPS antenna section)
and GPS signal strength using vmAIS.
Green Flashing
Antenna VSWR is high
Check your antenna installation. Use the VSWR meter in the
vmAIS status page. A poorly tuned antenna, bad cabling
or connections are typical reasons for a high VSWR. Your XB
will continue to operate normally but transmit performance
will degrade.
Background noise level on AIS receiver channel is high
An AIS receiver channel has an abnormally high
background noise level. Determine the channel and
frequency by using the vmAIS status page. Look for an RSSI
level greater than -77dBm. Remove any sources of noise
onboard at this frequency. Your XB will continue to operate
normally but receive performance will degrade.
Red Solid/
Flashing
Built in integrity test error
An internal error has been detected. The XB may
automatically recover, but if the error state persists
