AIS 7- LONG RANGE (LR) DISPLAY

This display shows a list of queries by other AIS stations going through the INMARSAT-C

or other long-range communication systems. The MX512/AIS can be set to respond

to long-range interrogations either automatically, manually (default) or by external

application.

When the setting is in AUTO, the MX512 will provide the requested information

automatically. When in MANUAL, the operator needs to highlight the

softkey and

press the ENT key to reply. This softkeys can be brought up by pressing the EDIT key.

Every time a long range query is received, the MX512 will pop-up a message window

accompanied by an audio alarm. When in “Ext Appl” mode the external application will

need to respond to the MX512/AIS with permission to reply.

To look at the long-range list, press the AIS key several times until it shows the AIS 7

Long Range screen (as shown).
