AIS Transponder TESTS

Set Number
As you may wish to test several transponders under the same MMSI, each transponder can be
given its own individual set number for recognition. Default number is 1. Press OK to confirm, or
press ↑ or ↓ to change to another number. Then, press OK and go to the test you wish to
perform.

Receive AIS sele

In the Receive AIS sele test mode, the test box will receive the selected transponder's MMSI
number and AIS data, and at the same time measure the frequency and the forwarded and
reflected power. The test can be performed on AIS1 and AIS2 respectively.
It is a requirement that the MMSI number registered in the test box is identical with the MMSI of
the AIS transponder to be tested. Please check and change number, if required, using the Edit
ship's MMSI menu. See Page 12.
Select Receive AIS sele on the test box and press OK. Select AIS channel and press OK again
to request for data. It may take up to 20 seconds until the AIS transponder transmits its data.
Test results are displayed line by line. You may toggle between the lines using ↑ and ↓ to view
all the results. Results are also stored in the test box memory.
Use this setup:

The test box must receive AIS data on RF IN in order to start the power measurement. If the
test box keeps waiting to receive for some time, it is likely because the AIS transponder is still
waiting to transmit its data. Please note the transponder's reporting interval depends on the
ship's speed. The lower speed, the longer interval. Reporting Intervals for ships at anchor or
moored may be up to 3 minutes for each AIS channel.
You can check that the test box is able to receive AIS data from the actual transponder by
requesting a Message 5 or 24. See page 28-29. Upon these requests the transponder should
respond within a few seconds.
