LED indicator functions

Green LED indicator

Indicates that the AIS transceiver is configured, powered up and has transmitted (B92x variants). Indicates that the AIS transceiver is configured and powered up (B95x variants).

Red LED indicator

Indicates that the AIS transceiver has detected a system error. The likely causes of this are detailed in the troubleshooting guide in Section 5. Alarms displayed in the Diagnostic tab of proAIS2 or in CONNECT-AIS will also assist with troubleshooting.

Blue LED indicator

Indicates that silent mode is enabled. Silent mode is a feature of the B900 Series that ceases the transmissions from your own vessel, whilst the reception of other vessel position reports continue.

You can activate this using the configuration tools or by activating the toggle switch as detailed in 1.

Amber LED indicator

• If the LED indicator is flashing it means it is attempting to get a GPS fix. The GPS antenna status can be confirmed using the configuration tools.
• If the LED indicator is solid it means that the AIS transceiver is not transmitting. This can be for a number of reasons including:
• The AIS radio channels are exceptionally busy so there are currently no available slots for transmission.
• The unit has been in silent mode and after deactivating silent mode this amber LED indicator will illuminate until the first AIS message has been sent
• The AIS transceiver has been commanded by the local authority (via an AIS base station) to cease transmissions.
