MPX Extender Installer/User Guide Select the radio button that enables wired operation. NOTE: The IP address of MPX receiver’s media LAN port is dynamically assigned by its transmitter at bind time. This process is similar to DHCP. Although it is not possible to explicitly configure the IP address of the media LAN port of MPX receivers or transmitters, it is possible for 4 MPX transmitters and bound receivers to share a single wired extension network.
Chapter 3: Installation need to adjust the transmitter power setting, refer to wireless transmission power settings on page 41. Setting explicit receiver bindings (Suggested) By default, a transmitter honors requests from any receiver that requests binding. You may, however, configure a transmitter to honor bind requests only from a list of specific receivers. Requests from non-selected receivers will be rejected by the transmitter.
All units should be at revision 1.2.1.x or greater. Visit the Avocent web site at www.avocent.com and review the available upgrades. Should you decide to upgrade your units, see Upgrading MPX Firmware on page 75 for detailed instructions.
Chapter 3: Installation Receiver Configuration Accessing your receiver’s web interface The on-board web interface of an MPX receiver may be accessed indirectly through the control LAN port (L1) of the transmitter or directly via the control LAN port of the receiver itself. By default, the transmitter forwards web traffic between its control LAN (L1) port and its media LAN (L2) port or wireless LAN interface (which ever is active).
RGB displays if the display and video cabling supports DDC functionality; and component video displays if the optional Avocent component adapter-cable is used. NOTE: When set for Plug-and-Play, MPX receivers are able to distinguish an RGB display device from the EDID information received from the display.
Manual (Component): This setting must be selected to cause the receiver to output component video if the optional Avocent DVI to component adapter-cable is not used. In addition, this setting requests the receiver to generate EDID information on behalf of the component display device.
The Remote Console feature allows for centralized control of the MPX extenders that are deployed at remote locations. Contact Avocent technical support before you enable this feature.
Chapter 3: Installation 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.
MPX Extender Installer/User Guide Transmitter and Receiver Placement To find acceptable locations for your extenders: Turn off all MPX extenders. Turn off your source and display devices. Place the transmitters and receivers in their desired locations without firmly mounting the units. If you have a PC-based application that is able to detect nearby access points or if you have a handheld spectrum analyzer, use it now to identify unused channels.
Orient your antennas as needed to account for: Antenna polarity: RF antennas are polarized. The default MPX antenna is a dipole antenna, which emits and responds to vertically-oriented RF signals. The Avocent UNI-8DB antenna, unless otherwise marked, emits and responds to horizontally- oriented RF signals.
MPX Extender Installer/User Guide Figure 3.9: Vertically aligned antennas Reflections: Depending upon your environment, it might be advantageous to orient the antennas on your transmitters and receivers such that one antenna on each unit is upward in a 12 O’clock position and the other antenna is perpendicular to it, in a 3 or 9 O’clock position.
Chapter 3: Installation Attach the video display and audio devices to the MPX receiver(s). Turn on your audio and video devices. 10. Turn on your MPX receivers. 11. Turn on your MPX transmitter and wait for the receivers to bind. 12.
