Initiating A Media Session

Your MPX extension network is now ready for a media session.
The following steps allow you to verify proper operation of your transmitter, receivers, establish an
Active EDID string at the MPX transmitter and test compatibility of your source and display
devices through the extension network.
To establish your first media session across the extension network:
1. Turn off your MPX transmitter and receivers.
2. Turn off your display devices.
3. Properly shut down off your source device if it is not already turned off at this time.
4. Attach your display device to the primary MPX receiver using an appropriate cable.
NOTE: If your display device does not support DDC2B or if a cable or video switching device prevents the
normal flow of EDID information across the DDC bus, then refer to Common Tuning Needs on page 75 for
additional information. Please do so before moving on to the next step.
5. Power on the display device.
6. Power on the primary MPX receiver.
NOTE: This power up sequence ensures that the display device is online when the MPX1000 receiver reads
EDID information from the device.
7. Attach the source device to the MPX transmitter using an appropriate cable.
8. Turn on the MPX transmitter.
9. Wait for the MPX receiver to bind with the MPX transmitter, as previously described.
10. Power on your source device and activate as necessary to ensure flow of video data.
NOTE: This power up sequence ensures that proper EDID information is stored in the MPX transmitter before
the source device attempts to read it. The order of power up sequencing is important only once, during initial
configuration and setup. If it is necessary to replace a field-installed MPX transmitter with brand new unit, these
same steps should be used to properly establish valid EDID information in the replacement unit.
11. Active video should appear on the display device attached to the MPX receiver within 30
seconds after the source device has completed initializing.
12. Additional receivers and display devices may now be added to the extension network.

Troubleshooting

If video fails to appear on your display device or if plug-and-play functionality is not functioning
normally, see Video Troubleshooting on page 74 for detailed troubleshooting procedures.
