    5. Antenna extension cables result in signal loss. When possible, move the transmitter or receiver into the desired position in lieu of using an extension cable. When cables are necessary, use the shortest Avocent-certified cable that allows you to properly position your antenna. Daisy-chaining of antenna extension cables is not supported. Carefully follow the installation instructions provided with your cable kit and properly configure the extender when using extension cables.

    4. The Remote Console feature allows for centralized control of the MPX extender system. Contact Avocent technical support before you enable this feature. NOTE: The Remote Console feature should only be enabled on a secure network, as it potentially creates a security hole.
  • Page 26 Emerge® MPX Extender System Installer/User Guide Figure 2.2: Transmitter Basic LAN Settings An MPX 1550 transmitter is a specialized wireless access point. It broadcasts a name (ESSID), which enables MPX receivers to locate and bind to it. Although it is not possible to alter this name, you may disable the broadcasting of this name if all receivers have been explicitly configured with the MAC address of the transmitter.
  • Page 27 Chapter 2: Installation To attenuate transmission power: 1. In the Transmit Power Attenuation drop-down menu, select the appropriate attenuation value. 2. Apply the change. NOTE: Selection of this setting causes the transmitter to temporarily drop active bindings. NOTE: Each 3dB of attenuation reduces signal strength by one half. Thus, the setting for -3dB results in one-half power.

The MPX 1550 transmitter supports both the wireless (default configuration) and wired LAN interfaces.

  • Page 29: Access Point Installation

    Chapter 2: Installation NOTE: The IP address of the MPX receiver’s media LAN port is dynamically assigned by its transmitter at bind time. This process is similar to DHCP. 4. You may place more than one transmitter on a wired media LAN. Skip to the next step if you are only installing one transmitter.

  • Page 35: Setting Explicit Receiver Bindings (Suggested)

    Chapter 2: Installation • Designation of a specific transmitter ensures that rogue transmitters are ignored by your receivers. • If all receivers are tied to specific transmitter, it is possible to disable ESSID broadcast on your transmitter. Disabling of ESSID broadcast provides yet another layer of security for your system (MPX 1550 extender system only).
  • Page 36 Emerge® MPX Extender System Installer/User Guide • Explicit bindings allow for the selection of a primary receiver, which enables the following functionality: • It allows for bi-directional serial and IR communications. Without a primary, serial and IR data is broadcast by the transmitter to all receivers and return data are ignored.

    Chapter 2: Installation NOTE: (Optional) You may manually enter a receiver’s MAC address. MAC address labels are affixed to the bottom of an MPX receiver. Figure 2.7: Bindings Page Transmitter and Receiver Placement (MPX 1550 System Only) To find acceptable locations for your units: 1.
  • Page 38 Antenna polarity: RF antennas are polarized. The default MPX extender system antenna is a dipole antenna, which emits and responds to vertically-oriented RF signals. The Avocent UNI-8DB antenna emits and responds to horizontally- oriented RF signals. When signals pass between these two types of antennas, one must be rotated into a 3 or 9 o’clock position.
  • Page 39 Chapter 2: Installation will not intersect. In this case, signal strength may be optimized through appropriate up or down tilt of their respective antennas, as illustrated in Figure 2.9. Notice how the primary lobe of each beam of each antenna is tilted toward the other antenna. Tilt is accomplished by a slight rotation of the antenna at its base or tilting of the articulating arm of the antenna in the appropriate direction.
  • Page 40 Emerge® MPX Extender System Installer/User Guide Figure 2.9: Vertically Aligned Antennas • Reflections: Depending upon your environment, you may want to orient the antennas on your transmitters and receivers so 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.
  • Page 41 Chapter 2: Installation care to evaluate only those channels that are compatible with the antennas that you have selected. For example, do not test G band channels with UNII band antennas. 7. Once acceptable signal strength is attained, turn off the MPX transmitter, access points and receivers.

Bi-directional IR data is limited to the transmitter and the primary receiver. NOTE: For clarity, the flow of IR data from the IR(Rx) port to the IR(Tx) port on the same MPX extender system unit is referred to as IR local loopback and the flow of IR data across the extender network is called IR extension.
  • Page 62 A single IRB-100 dual emitter is supplied with the MPX transmitter. Should it be necessary to control more than two source devices, Avocent offers the IRB-Y splitter, which allows two IRB-100 dual emitters to be attached to a single MPX transmitter.
