4.18.2 Using Port Viewers for IFBs
You can use an unpopulated (empty) Port Viewer to dynamically manage your IFB setups.
To use a Port Viewer to manage your IFBs:
1. Define all IFB destinations, program feeds and interrupt sources in EHX and then download to
the matrix.
Note:
In EHX > Advanced Settings > Global Settings, ensure that Global IFB is set to True for all
IFB destinations (normally four-wire ports). You should also ensure that the audio dimming
level for IFB destinations is configured.
Tip: For more information about EHX, see EHX Help or your EHX documentation.
2. Create an IFB system, comprising an IFB destination and program feeds, by dragging the IFB
destination (normally a four-wire port [ ]) into an unpopulated (empty) Port
Viewer [ ].
The IFB destination becomes the monitored port, and the program feeds are added to the
connections list of the Port Viewer.
In the procedure above, the program feeds placed in the Port Viewer are heard by the IFB
destination.
If a talk key on a panel [ ] that has been assigned to the IFB destination (the panel is
an IFB source) is selected, then:
• An audio path is established between that panel / IFB source and the IFB destination.
• The program feeds are dimmed.
• The panel / IFB source audio is heard by the IFB destination for as long as the audio path is
present.
If the IFB destination is also a member of a conference [ ], then:
• The conference is added to the Port Viewer.
• The conference audio is heard by the IFB destination.
