Performing a SWiM Channel Assignments Test
You can use the AIM’s SWiM Channel Assignments test feature to view the Receiver IDs
(RIDs) and assigned SWiM or DSWiM channels for each IRD in the installation. If you suspect
that the network could be oversubscribed, the results show whether all available SWiM or
DSWiM channels are used, indicating the possibility that the number of IRDs in the network
exceeds the SWiM’s capacity.
To perform this test, connect the AIM at any point in
the distribution network between the SWiM and the
IRD. Power for the SWiM must be provided by an
external power inserter, since the AIM cannot be used
to provide power during the test.

Starting a Job section in Chapter 5 .
2. From the HOME screen, press TEST to go to
the TEST screen.

press SELECT to go to the SWiM CHANNEL

4. Connect the AIM ODU F connector at any
point in the distribution network between the
SWiM and the IRD. Make sure that power for
the SWiM is provided by an external power
inserter.

the test. screen.
The DSWiM requires an open channel to run the test. If all
channels are subscribed, a message appears stating that all
channels are occupied and to remove the IRD and try again.
